Hard drive not recognized by BIOS but recognized by WINDOWS Inspiron 9300

Q: Hard drive not recognized by BIOS but recognized by WINDOWS Inspiron 9300

I tried replacing the hard drive on my Inspiron 9300 with a 200G drive. The administrative computer tools in Windows XP recognized it, but the BIOS showed it as 130G or so. I finally had to replace the drive with a smaller one. I had the latest BIOS version. Is there a BIOS fix that will allow the larger hard drive to be used?

Preferred Solution: Hard drive not recognized by BIOS but recognized by WINDOWS Inspiron 9300

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Hard drive not recognized by BIOS but recognized by WINDOWS Inspiron 9300

Not on the 9300s that use EIDE (parallel ATA) drives, no - the limit is 137G in BIOS setup.

The BIOS automatically updated and now it no longer recognizes my secondary hard drive in the laptop. Other than this, the laptop is functioning fine.

My Inspiron 7559 won't boot, giving the message that hard drive not present/not found. This happened just after I received the laptop back from Dell. I had sent it to Dell without the hard drive for an ethernet card replacement. When I re-installed the drive, it would not boot. It was fine before I sent it.
However, BIOS identifies it as a Seagate Sata drive while Dell Diagnostics declares that all laptop components, including the hard drive are fine.
I first got the PXE-E61:Media test failure, check cable error. I soon learnt that this merely meant Bios could not find an internal hard drive and was searching for a network boot. Once I turned off networking in BIOS I went to a simple, no hard drive found error, which is where I am now.
The hard drive may or may not have failed. I've run six hard drive testing programs on the drive in an external dock. The results are ambiguous. Three (Macrorit, EaseUS Partition Master and Western Digital Drive Tester) all give the drive a clean bill of health. Three others (HD Sentinel, HDD Scan and  Crystal Disk Info), however, all reports various degrees of ill-health. Copies of the results of these tests are attached in a PDF file.
Anyway, I can read and navigate the drive with Windows Explorer in an external dock.
I don't want to abandon the drive as I have a lot of software loaded that I can't easily or plain can't reload.

Hey all,
I had 3 hard drives connected to my pc with 1 IDE for booting windows and the other and the other 2(SATA and IDE) for storage. I did a reinstall of windows and now my IDE storage drive is not recognized by windows. I looked at the hard drives under computer management but it does not appear at all. It does show up in the bios though. I checked the jumper setting and even tried connecting via usb with an external enclosure. With the enclosure it just found the hardware but no drive on 2 different computers.

Recovering the information on the drive is ideal, but not necessary. That said, does anyone have any idea how to fix this? If I do not find a solution, is there any way to format the hard drive without windows? I thought about installing a different OS on another computer just to format the drive but was not sure if this would work or if there was an easier way.

Thanks in advance.

A:Hard Drive recognized by bios, but not windows

If you are using Vista/XP/Server 2003 or Seven, you can look in Disk Management.

Go to computer management (right-click computer then Manage)

On the left of the window, select Disk Management.

This will show not just the drives, but also the partitions on the drives.

It may be that the drive has become corrupt or is formatted in a way that Windows does not understand. Alternatively, it may just need to be assigned a drive letter.

Hello! Having some serious issues, as it seems we all have. So, here's the situation. As a nerd truck driver I bought a laptop for skyping with the family and playing games. Laptop was working fine one night and the next morning I start it up and windows won't boot. Just gives me a blank screen with the infamous blinking cursor in the top left.

After searching the forums, it appears I need the Win7 install discs, which this computer did NOT come with. I may be able to get my hands on a reinstall disc, but I doubt it'll be a samsung laptop disc. I was, however, able to make a recovery disc from my wife's Dell laptop. I thought she had a reinstall disc, but we can't find it.

My current problem, and the most troubling, is that now BIOS doesn't even show the HDD. I checked the connections and they are fine, and I was able to put the SATA drive in my desktop and copied all my important data to my desktop. So I know the drive is good. Nothing is corrupted and all partitions, including the recovery partition is intact. I can't figure out why the laptop isn't showing the drive in BIOS now, though.

I've tried the recovery disc a second time, but it doesn't seem to want to boot correctly now. It worked fine when the HDD was recognized, but now it's getting to the blinking screen, then the cursor jumps to the bottom right and pixelates across the bottom of the screen like it's trying to load.

I can probably get my hands on a reinstall disc if I can download one or ask around tomorro... Read more

A:Hard Drive first not booting Windows, now not recognized in BIOS

Ok, I got the recovery disc to boot again, but still don't have the HDD in BIOS yet. Only option that works in the recovery disc is the command prompt. searching for the HDD that way, but so far, I have only found D: which has the Dirs: Boot, and Sources, and a file called bootmgr. This is along with X: which is obviously the recovery disc. So far, I can't find anything else.

I just rebuilt an old system using Windows 7 Home Premium after using WinXP pro for many years. The primary hard drive is WDC 150 Mg and Win7 is installed and updated to current with SP1. I dropped a second WDC hard drive in, formatted and was going to use it for a 2nd backup unit. Both of these are sata. Both hard drives are recognized by Disk Management but when I select Computer on the start menu ONLY the primary 150 Mg drive is recognized. If I plug in an external drive, both Computer and Disk Management recognizes the external drive. How do I have Win7 recognize my backup WDC drive so I can use it.

Thank you

Had similarities on my pc.

Goto BIOS, there you have 4 options.

Primary Master
Secondary Master

Primary Slave
Secondary Slave

Set it as follows:

Primary Master -----> Main Boot HDD
Secondary Master -----> EMPTY

Primary Slave -----> CD/DVD RAM
Secondary Slave -----> Secondary backup HDD
Hpe it helps!

AMD Athlon 2200+ with 256MB of DDR Ram.
Biostar M7VIQ motherboard
60GB hard drive

Computer has been starting erratically for awhile. Sometimes it will start., other times it fails and says "HARD DISK NOT FOUND..."

I think the hard drive it finished. With power on I do not feel that 'gyro' effect you normally feel from spinning platters in a good drive.

So I tried a brand new 80GB hard drive. After numerous reboots the BIOS finally recognized it. I was then able to install WinXP. When installation was complete, I did a few Windows updates. Now I'm getting "HARD DISK NOT FOUND..." message again.

Thinking the motherboard battery could be failing, I tried a new one. Made no difference.

I tried new IDE cables. Made no difference.

I set BIOS settings all to default settings. Made no difference. Tried optimized settings. Same thing.

I'm running out of ideas. Anyone have any idea what could be wrong?

PS: Bootup each time is EXTREMELY slow.

Hi every body, I am new to this forum. I have fair amount of experience with PCs, including building them. Now I have a new problem. I installed a new HDD, configured it as the Primary 'o' drive (Cable Select). No other drive. The single drive is detected by the BIOS. When I try to install Win XP, the setup loads the necessary files, but when I hit Enter to install OS, I get a message saying "No hard drive is found".

I have tried different hard drives changed the cables, tried it as Master, nothing works, same message. Would appreciate your help.

A:Hard drive is recognized by BIOS, but not byWin XP installatio

Normally this has to do with Windows not having the drivers for the controller. Usually the driver is on a floppy disk or on the CD that came with the motherboard and will need to be put on a floppy disk.
During the install you will be prompted to press F6 to install additional SCSI or RAID drivers. This is where the controller drivers will need to be installed.

Can you list your motherboard specs and we may be able to find you them.

Recently I decided to upgrade my hard disk storage space so I bought a Maxtor DiamondMax Plus 9 160GB SATA hard disk drive. Upon installing the drive I entered the Bios and went into "Intergrated Peripherals" section and set the BIOS to recognize P-ATA + S-ATA drives. When I reboot the new Maxtor drive shows up in Windows Explorer and functions normally. Also in Windows Explorer, my CD/DVD drive appears. However when I put a cd in the drive and click on the drive in Explorer I get the message to "Insert a disc into drive F:". The drive will not read the disc. When I went into Device Manager the CD/DVD drive shows up and says that it is functioning properly. Strange.....
So, I rebooted and reset the BIOS to the setup defaults (ie. P-ATA Drive Only) and when the computer boots up now the CD/DVD drive functions normally but the Maxtor drive is now not recognized. I understandObviously the Maxtor drive is not recognized because the BIOS is set for P-ATA drive only, but why when the BIOS is set for P-ATA + S-ATA is the CD/DVD drive not recognized?

I have a Dell Optiplex GX280 SD. When I first purchased the PC it came with a CD-ROM drive and Windows XP Professional pre-installed. A few months after purchasing the computer I decided to upgrade my CD-ROM to a DVD-RW/CD-RW. I purchased a brand new DVD-RW/CD-RW drive and replaced my CD-ROM with it. Everything worked well, I was able to play CD's, burn movies, etc. A month later I decided to upgrade my Windows XP with Windows Vista Home Premium. I purchased the DVD and installed it with no problems. My DVD-RW drive worked fine, even after installing Windows Vista.

Then, a week or two later I tried playing a CD; I opened my DVD-RW/CD-RW tray, placed the CD inside, then closed it. Usually when I place a CD into my DVD-RW/CD-RW drive and close it a window pops up asking me what I want to do, however, this time it didn't. I went to My Computer and noticed that there was no DVD drive icon under Devices and Removable Storage. I tried restarting my computer in hope that it would reappear but it didn't. I went to Microsoft's website to try and figure out what was the problem. One option was to go to Registry Editor/HKEY_LOCAL_MACHINES/SYSTEM/CurrentControlSet/Class/{4D36E965-E325-11CE-BFC1-08002BE10318} and delete both upper filter and lower filter; however, I was only able to delete upper filter because there was no lower filter.

A:DVD drive not being recognized by neither BIOS nor OS (Windows Vista)

Hi lechevarria89,

Is the drive SATA or IDE? You've established that it is getting power to the driver, but not the information. And since it is not showing in BIOS, but was previously. We start looking at the physical information connector. SATA cables quite often fail, plus make sure the cable isn't bent at a 90 degree angle, with SATA the rule of thumb is "Mess is good!"

I noticed that sometime after I installed windows 7 that my dvd optical drive was not showing up. I have done a lot of research on the matter and have yet to find a working solution. I checked my BIOS and the drive is not listed there, but I'm pretty sure it is properly connected. I have an HP Pavillion dv6000, so the drive just plugs into the slot directed connected to the motherboard, and can be removed by unscrewing a single screw. When the laptop is on I am able to open the drive, and it lights up, so I know it is getting power... I have tried everything under the sun to fix the problem - checking/cleaning the connection port, deleting the upperfilters value from the registry (which many people have said worked for them, however for me it only gave me an warning message in itunes telling me the registry files for burning/importing cd's was missing), reinstalling gear drivers, and running the microsoft fixit programs (they just tell me they can't find the drive or that it isn't there - thanks microsoft...). Nothing has worked, and it's driving me crazy not being able to use my dvd drive. Has anyone had this problem to the same degree as me?/found a solution to it?

A:DVD Optical Drive Not Recognized in Windows or BIOS

Of the BIOS cannot see it, no software fix will help including other drivers. It is probably a connection problem. If the disk works, then the mobo controller is OK because the optical drive uses the same controller in the chipset.

I bought a WD Scorpio Blue 160 gb hard drive . Salesperson said I could go up to a 250 gb, but I didn't think I needed too. I just now read here about the BIOS not liking anything more than a 120 gb , that's fine, I'll partion and take chances.

A:Inspiron 9300 Hard Drive Upgrade help

Chances are you missed the blade adapter -- transfer it from the back of the original drive to the new one, or the drive isn't connected to the system board.
For the sake of your data, yes - make sure you make a 120G partition and install Windows to it.  DO NOT use a single partition the full size of the drive or you WILL lose data.

I have a Dell T3500 with one (1) hard drive. I want to add a 2nd SATA hard drive. I'm running Win 7
64-bit in a non RAID configuration.

My C:\ drive is connected to the SATA-2 port on the mobo.

I installed the 2nd drive and connected it to the SATA-0 on the mobo.

First question: does this matter? Do I have to order them nicely (SATA-0, SATA-1, etc.) or not?

At first my 2nd hard disk was not visible in Windows Explorer. It wasn't even visible in Disk Management. But I managed to solve that myself. I Googled it and turns out you have to F2 your way into the BIOS and there are checkboxes which SATA is activated, or not. Turns out SATA-0 was deactivated. So I activated it and could not boot. Hit Ctrl-Alt-Delete and changed the boot sequence in the BIOS. Back in business. So now my hard disk is recognized and visible in Disk Management.

Second question: do I have to format it?

The 2nd hard disk is shown in Disk Management as Disk 1. It has 4 volumes:
2.38 GB Healthy
2.00 GB Healthy
128 MB Unallocated
1858.51 GB Healthy

Right clicking the Healthy volumes only shows one option: Delete Volume. The rest is greyed out.

Right clicking the Unallocated volume shows one option: New Simple Volume.

Third question: now what? Can I reduce the number of volumes?

Okay so here is the situation, I'm trying to install windows XP on my new SATA hard drive.

The problem is, when I put the windows CD and boot from it, I press ENTER to install windows and it said it couldn't recognize a proper hard drive to install on. It tells me to press F3 to quit.

This is what I've noticed/tried,
1) I checked to make sure there are no cap switches on any of the hard drive pins
2) I checked the BIOs and the hard drive IS properly detected
3) I put in the CD that came with the hard drive and format than created an NTFS partition
4) I tried other SATA slots on the motherboard
5) I have an extra hard drive with windows already installed. I put the old hard drive in and left the new one out. When I tried to enter recovery console with the windows XP CD i got the same message about how it couldn't recognize the hard drive.

Any ideas? I am completely lost.

Hi there,

I just reinstalled Windows 7 after upgrading my mobo, ram and cpu. As it stands my Maxtor 300gb hard drive, is showing up in the Bios. In fact it shows up in the Device Manager in windows. But when I go to the Computer Management to try and assign a drive letter to it, it's not there. My main drive was assigned D, probably due to my external hard drive being plugged in during the install. Whoops.

But does anyone know why I can't get windows to see it? Even though Bios and the Device Manager see it.

So..I'm pretty much a noob when it comes to this stuff. I couldn't see any other question posted that was similar to mine.

I have a compaq presario. I recently obtained a virus on my computer so I proceeded to do what I always do, reload my OS, which is windows 7 ultimate by the way.

However, when I popped in the CD to boot from, it doesn't recognize both my hard drives. It recognizes the hard drive I use for storage (the drive that the virus did not spread to) but it doesn't recognize the hard drive with my OS, the one I boot from. (the one that is crippled with the virus)

So I know that this question is probably ultimately a virus issue but I basically just wanted to know if there was a hardware setting that can be changed to get the drive to be recognized so I can install windows on it.

The hard drive in question is a ST3160812AS SeaGate 160 GB, I already tried disconnecting the other hard drive but when I get to the intall step in the installation process it doesn't display a hard drive to intall the files too.
I am not sure if my hard drive is fried now due to the virus or if I need to install drivers..I tried finding a place when I can download the drivers but I couldn't find any.

Checked the BIOS (without the boot cd in the cd drive, and with my other hard drive disconnected) and the drive is recognized there, do not know if this helps but in the BIOS main page it reads:

A:Reloading Windows and my Hard Drive is not recognized

Download Seagate's drive testing utility and burn it to CD. Get the one that runs from a boot CD. Use that utility to both test the drive and/or write zeros to the drive to clear it of any possible problem in the file, or partition table.

Or, you can send me a mail at {address removed as lo longer needed} and I'll send you a little utility called ZAPART that will clear the drive's partition table in just a few seconds. It runs from any bootable disk -- Windows 95/98, DOS6 floppy or CD.

You'll have to remove the dashes, backslash, spaces and equal signs from the address above.

Alright well I've been working on trying to get this work for what seems to be forever now. At least a good week or so. Here's the deal:

I built this computer myself 3 years ago, and my current hard drive just fried and i had to replace it. So, i bought a new Hard Drive (250gig hitatchi deskstar: model number: HDT725025VLA380) and plugged it into the computer, bought a new Windows XP CD (old one was scrached for some reason) and started to run Windows XP so i could get everything back up and running. I go through, Press F6 on the screen that comes up to install SCSI/RAID drivers and such. Hit S to download from a floppy, then select the driver that has (Windows XP) next to it. hit enter, sends me back to the same screen i hit S on, then i hit enter again to continue.

Here's where the problem kicks in, window then sends me to the screen where you hit hinter to install a new windows, and then R to repair. I hit enter, and then it says "setup did not find any hard disk drives installed on your computer."

The drivers i tried to install are the Windows 2000/XP drivers (not the windows XP 64bit) that are on MSI's website for the motherboard I have:

Hi there,

I have an Acer Aspire 5610 laptop. Windows died recently and if I use the Acer recovery program I will lose the contents of my hard drives - something I am very keen to avoid. So I got my hands on a Windows XP Pro CD and have installed Windows. The problem is now I cannot for the life of me get it to recognize my Maxtor USB external hard drive. I've installed every little thing I can find on the Acer/Intel/Microsoft/Maxtor websites etc but still nothing. I've tried uninstalling the USB ports and reinstalling them - still nothing. I've checked device manager to see if it's recognized but not mapping correctly - it's not in device manager. I went into my BIOS to ensure that USB was enabled and it's not an option in the menu (I have PhoenixBIOS). I have tested the External Hard Drive on other PC's and it works fine. When I plug it into my notebook it plays the sound to say it's recognized a USB input and then the USB symbol displays in the Task Bar with the Message "Device Not Recognized" - what can I do to get this to work - I've spent 26 hours so far and nothing has worked and it would take me forever to back 120GB onto DVDs! Any suggestions would be greatly appreciated!

Suddenly, my computer freezed (just like it has been doing for some time now).
When I restarted it, the computer asked for the Vista DVD, so that it could repair some files (I couldn't even boot into Safe Mode). I put the DVD inside the drive, and choose the "Repair your computer" option, but it reports that no Vista installation is found...

I then boot into the Rescue and Recovery environment (that is a Thinkpad suite, located in another partition of the disk) to see what's going on.
The System Information detects everything except the Hard Drive (it reports "Not Available" for the fields "Hard disk free space" and "Hard disk capacity"). I also can't see the harddisk in the option to backup the files to a pen (the pen is recognized, though).
Just to be sure, I run PC Doctor and my hard disk passes all tests.

My son tried a new 80 gig ACOMDATA external drive on his MAC before he gave it to me as a gift. The drive as a new device will not initialize on my WINDOWS ME based Gateway Athlon PC. No drive letter is assigned yet the green arrow in the trough in the lower right of the desktop shows a drive with no letter assigned. MYCOMPUTER shows no new device. I read the Quickstart literature for the drive and it states that use on multiple platforms MAC & PC is available. Unfortunately it also states that to do this the drive should be started up first on the PC and second on the MAC. Since this order was not followed I suspect the drive has a MAC file system on it and the PC refuses my access to intialize it. Does anyone know how to fix this problem like' How do I reformat a disk if I have no drive letter' or does the MAC side offer some solution. So far my multiple Email's over the past 7 days to ACOMDATA have not been answered. So much for there 72 hour(3day) response time. Do I have to give this drive back to my son for his permanent use and buy a new drive? Do all USB/FIREWARE external drives have this quirky capability and init sequence requirement?

I'm having a similar problem to the one posted here.
I've added a second HD as the master drive on my secondary IDE cable. It is recognized under BIOS and Device Manager, but not under Windows Explorer.
I went to Disk Management and the drive is listed as "Healthy (Active) status. It does not have a drive letter and the file system is blank.

I'm hesitant to partition the disk though, as it is my backup disk, with all of my documents and other files on it. (This makes me extra concerned as I just noticed it also lists the drive as 100% free.) The drive was working fine on the same hardware setup a week ago. I formatted to unclutter my XP, and I'm putting all the goodies back in the case now.

What can I do here? Is my data in fact gone? Or do I have options still? I'm getting more confused the more I figure out on this one...never a good sign, *sigh*...

Motherboard: ECS KM400-M2 (3.0) 462(A) VIA KM400 Micro ATX AMD Motherboard
ECS Web Site > KM400-M2 (V3.0)

I just purchased a new hard drive to use for hosting, as I am creating a server computer. I took that old motherboard, put it in a new CoolerMaster Case, along with a new hard drive WD 500GB (7200rpm 32mb/mo). The motherboard is IDE and SATA, and the new hard drives only have SATA connections of course. So, I purchased a power supply SATA adapter and I have a SATA cable running to the motherboard in the first SATA spot (SATA 1 [total of 2 slots]). The BIOS does not tell you which hard drives are recognized, but it allows you to have an initial bootup of first/second/third. Options include HDD-0 HDD-1 and so on. SATA is enabled in the BIOS and when I boot up, it starts the DVD-ROM drive, and not my Hard Drive. I have the windows 7 installation disk in there anyways, and it boots that up. I go through the setup and once I get to the point where you pick a drive, my WD 500GB Hard Drive isn't displayed. I do a refresh, and I tried scanning for Hard Drives, and scanning for Hard Drives that wasn't compatible with the Hardware. Nothing showed up. So, now I am stumped.

A:New Hard Drive Not Recognized During Boot-Up or Windows 7 Installation

Welcome Oh Great One

Try enabling the AHCI mode in the bios setup and see if it recognizes the WD HD that way. Also double check the Power connector & data cables and even try them on a different connection location.

I just built my first computer (specs in signature) with a SATA hard drive. I put the windows XP Pro CD and it formatted my Hard drive the it installed windows, but it says that windows could not start due to a hardware configuration problem. Is there some special thing I need to set to get it to boot from the drive or what? Any help would be greatly apreciated, thanks in advance.

A:Solved: Windows XP is not recognized on SATA Hard drive

There are many articles here within the forum and elsewhere on how to use Disk Management to get your External USB Hard Drive to be recognized in Windows so I won't repeat that process here.

The lack of external hard drive recognition issue may continue and if it does what a pain it is to have to go through Disk Management every single time to get Windows to see your drive.

If this is your issue follow these steps as there?s actually a very simple fix to all of this.

You have to get the drive to show up as mentioned above in Disk management. Once this is done, go to a command prompt (DOS prompt). There are usually shortcuts off the start menu for this DOS prompt or hold down the Windows Key on your keyboard and tap the ?R? key. The Run windows will appear. In the Run box type: cmd
at the flashing cursor type this string:
chkdsk /f g:
so it will look something like this:
c:\users\anthony\chkdsk /f g:
[NOTE: g: is an example. you replace the g: with whatever your external drive letter is along with the colon]
you?ll be asked to dismount the drive. type Y when prompted ? let the chdksk utility run its course until you see the drive letter with the flashing cursor such as
c:\users\anthony _
type: exit
you're are done.
To test, safely remove the drive using the Windows safe remove option near the clock. Once your cable is removed, wait a few seconds plug back in an walla! your drive will appear normally without going through all the above steps aga... Read more

I have a 120 GB Hard drive as my main drive that has my WINXP OS on it, and I have a 180 GB hard drive that I use to store movies, games, music, etc.
I ran a program called "Shred" which shreds free disk space on hard drives to free up unused disk space, essentially making sure that you don't waste space to deleted files.
I ran Shred many times before and everytime it worked fine, but I noticed after I ran it on my 180 GB drive I could no longer open folders on the drive. I restarted my computer and now found that the drive was no longer being recognized in Windows.
What's going on? Can i recover my data? I dunno what to do.. Thanks for your help guys..

I currently have 2 SATA hard disks connected, then 1IDE hard disk on blue IDE slot and 2 IDE cdroms on the other IDE slot. I also have two other external drives each connected to a USB port.

The problem is that the IDE hard disk is not being recognised in BIOS, when I try to switch some settings in the BIOS IDE configuration I have managed to get it recognised but then the cdroms are not recognised, how can I get them all recognised?

Another problem I have is with the external drives. If I switch them on before the computer boots up the POST will hang, so I have to leave them off until the POST ends and switch them on while windows loads so they get recognised by windows with all their sharing settings intact. Is there a way to eliminate this annoying problem?

I have an old PC (Compaq Presario Desktop 7470 ) that i purchased from a yard sale. I removed the old HD and replaced it with a quantum 30gb at Lct 20 HD that had Windows ME OS on it. I booted the pc and it booted fine except windows booted up in 16 bit color. I shut down and booted again. same thing. i shut down a third time and checked BIOS settings, then set them to default. Now BIOS doesn't recognize the HD or the CD-ROM drive. I have checked all connection, reset BIOS, removed the CMOS battery, I literally have tried everything I can think of to get things going on this old PC, but I am at the end of my rope. I will say that scandisk will recognize the HD and says it is OK. I have also taken the HD out and hooked it up to another PC and it boots up Windows ME just fine. I have also tried every jumper setting on the HD and Cd-rom to no avail and the only drive that shows up in BIOS is the 3.5 floppy drive which will boot up a Windows ME Boot Disk. I don't have a problem installing a fresh OS but want and need the PC to recognize the drives before i can do that correct?
I am ready to pull my hair out!! Can anyone please help me?!!!?

A:HD recognized by scandisk but HD not recognized by BIOS

probably the booting sequence is wrong due to the fact that you told the BIOS to load the preferred defaults. If you have a standard BIOS:

*go to advanced BIOS settings.... your going to see a big list of options .

<< check this picture for visual example>>
*take a look at the first , second and third boot device and change them to:

1- HDD - 0
2- HDD - 1
3- HDD - 2

Alternate them accordingly.

**probably the reason why your pc booted up at 16 bit the first time , may be
because you haven't installed the drivers for your video card yet.

I have a brand new Foxconn A7GM-S 2.0 motherboad which seems to be unable to recognize my two SATA hard disks. I have ensured that the power connectors and SATA cables are snug, and have tried each pair of the six SATA slots on the motherboard. I also don't hear either hard disk powering up upon boot.

This board is a replacement for my older motherboard, which died rather suddenly. Both hard disks were connected to the old motherboard at the time of its failure, which leads me to wonder if the disks are damaged beyond repair. Do motherboard failures generally affect connected hard disks? Or is my new motherboard defective?

CPU = AMD Athlon 64 X2 5050e
Motherboard = Foxconn A7GM-S 2.0 (BIOS version 8.00.14)

A:SATA hard disk not recognized in BIOS

Yesterday while watching movie on my PC it appeared as black on the screen and stopped working. After restarting the PC it was not responding as the BIOS was unable to recognize the hard disk. It creates an unusual sound while BIOS searches drives.

1. I tried by bootting the PC using another hard disk but this HD does not appear in the windows.
2. I also tried to boot using Ubuntu live CD but failed to find my HD on it.

As it is not recognized by BIOS, I cann't use data recovery software to recover the data. I'm badly in need of all data in it.

Please someone help me in this regard to recover the data.

Try the freezer trick. Place your hard drive in zip lock freezer bag to protect it from moisture and freeze it overnight (or a few hours at least). Quickly hook up the frozen hard drive and try to boot from it. If it works, be prepared to copy your important data as soon as possible before the hard drive warms up too much. This is not a permanent fix but it may work long enough to save your data.

Hi all,

I know this is similar to at least one recent thread, but different enough to post.
I am upgrading my sister's machine from a 3.2Gb WD Caviar to a 40Gb Seagate U Series 5 drive, ST348023 from memory, ATA100.
The machine is running a K62 266, not sure of the Mobo, but obviously supports the AMD chip.
From what I have been able to glean from the Seagate site, this drive should be backwards compatible with any IDE connector, but when I stick it in, with the BIOS set to auto-detect all drives, the machine halts trying to detect the Seagate drive, although it will let me Ctrl-Alt-Del and also press Del to get into CMOS setup.
I have tried it as Primary Master, and as Primary Slave, both with the other HD on the same cable, and without it in at all.
Seagate's disk tools are able to detect that it is there, even when not setup in the BIOS. Seagate's disk wizard, which is an excellent tool for installing a new drive, told me that all I had to do was set BIOS settings to auto for that drive, and all would be rosy. It looks at what drive you have, what BIOS you have, and gives you instructions to suit. The documentation tells me that if the BIOS supports LBA and Large disk types, then all should be fine - it does.

Can anyone give me any ideas on what's going on? I have installed quite a number of hard drives in the past, but never come across anything like this.

Hello all. It has been a while since I've needed help but my run of luck has hit an ugly downturn. Moved my computer three weeks ago and had not plugged it all back together till last night. All these years I had used it without a password to log in but a few months back a tech friend expressed horror at this so I started using one. Last night no matter what I did it wouldn't let me log in, saying incorrect password. Today as I messed around again I went through the steps of asking it to reset password (even though I didn't have disc for reset) and realized it does not seem to be recognizing my internal drive. If one of my externals are on they come up but if I turn off externals I get a bubble that says 'No Drive. This feature requires removable media etc.' My drive seems to be running and the Windows logos do appear during boot. My keyboard seems to be functioning to type password, but when I hit F8 while rebooting I get no reaction, so cannot boot to safe mode, just goes right back to log in page. I have had mold/moisture issues in this new house but have had a dehumidifier running since just a few days after computer arrived here. However I do see some evidence of mold or dust in the case, not a lot but some. Not sure what the root of this problem is but I am trying hard not to panic. Any ideas?

A:Internal drive not recognized/password not recognized

Your tech. friend may have mis-understood when you need a password.
If you are at home and only you and you trusted family have access to you computer, there is no need whatsoever for a logon password.
The only time I have ever needed one is when I was using my own laptop on clients site when I was contracting and I would leave it on the desk over lunch.

Hi everyone,

I have a Seagate ST320430A 20.4 GB ultra ata drive that will spin up but is not being recognized in either of two systems. The drive came out of a pc that was dying and I just rebuilt. I thought I had copied all the files I needed off of this drive. But now have figured out that of all the things for me to forget.... I didn't get the outlook.pst file. UGGG!!!

I've called a couple of local computer shops. The conscensus is that if it spins up but isn't recognized then the controller card on the drive is probably bad. If that is the case I'm being told that there's no hope.

1. Is it true that there's no hope if the controller card is bad?

2. What are the chances of me taking this apart and replacing the controller card from an identical drive?

3. I think I've set all the jumpers correctly for the drive. I can't remember if jumpers will prevent it from being recognized in the bios. I think I've tried all of the options though...


A:Solved: Seagate drive not recognized in bios

yes when the controller card on a hard drive goes dead then its usually comes to a dead end, personally i have never tried to rip it open and try to replace the controller card, something you could try and do if you wanted to try it, but wouldnt get your hopes up. as far as the jumpers go it doesnt matter where you put it on the hard drive it would show up in the system somewhere you would just have some conflicts going on that would let you know that you need to redo your settings on your drives.
