Rewriteable DVD not recognized - All other media recognized

Q: Rewriteable DVD not recognized - All other media recognized


My laptop does not recgonize DVD+/-RW. It recognizes all other media except rewriteable DVD.

Following are my specs
OS: Windows Vista Home Basic
Laptop Brand and Make: Sony Vaio N Series (VGN-N37GH/B)
DVD Drive: Sony DVD RW AW-G540A ATA Device
DVD Media Brand (which I tried): Sony DVD-RW

What I've tried:
1)Reached out to Sony support and they suggested removal of upper filter and lower filter as per Microsoft KB (http://support.microsoft.com/kb/314060)
2)Uninstalling Roxio and Nero
3)Reinstalling Nero

I am attaching output of Nero Info, Error during the burn process, screenshot of Nero Info Tool and screenshot of Nero Express Essentials.

Not sure what is wrong where and sony support as usual is not helpful...
Please heeeellllllppppp......

Preferred Solution: Rewriteable DVD not recognized - All other media recognized

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: Rewriteable DVD not recognized - All other media recognized

Your DVD player may not be re-writeable. Check your specs. Some players are read only and some are read/write. At least this will help you to the next step in determining a solution.

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?

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.

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

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!

I have a PC which is having a lot of trouble recognizing a USB data acquisition device. Starting from a situation where the PC *does* recognize the device, here is the basic pattern:

1. PC shows device in Device Manager under "Data Acquisition Devices".

2. If the PC is power-cycled via the power plug itself, the device is no longer recognized under Device Manager ("Unknown Device").

3. If the PC is power-cycled via Start Menu --> Turn Off, same results as above, no longer recognized.

4. If the PC is power-cycled via Start Menu --> Restart, no problems, device recognized.

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

A:USB Device Recognized / Not Recognized based on shut-down method

You could try reinstalling the usb drivers.
JohnWill has fix that is worth a try

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

I have an 8GB sd card i used while traveling and upon trying to get the pictures from it the computer does not recognize the card at all, no prompts, nothing. I have tried it in multiple pcs and macs and no response. My Cannon Rebel XS camera says no images found. However, when I plug it into my brother's Cannon PowerShot it actually recognizes and shows all pictures on the card. Does anyone have any reason why this is happening and how I can recover the pictures? I am not willing to just format to make the card work again, I must have these pictures.

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.

I recently purchased the Samsung YH-999 portable media player and for the past two weeks i simply cannot make it be recognized by windows.I followed the instructions as described in the manual for the player install and wmp10. The unit charges and powers on and i can see the various menus as well as see the drive capacity. It doesn't show up in My computer and Media player 10 doesn't see it also. I checked various forums to find a solution and tried the solutions mentionned and still no change. I always have to tell windows what kind of device i'm installing. In Device manager it shows up as MTP device and the properties tab tell me that the device is working properly. I tried the registry fix of the Enum hive and giving permissions to read acces to the Everyone group. I also tried the sc stop and start umwdf in the run window. In the control panel under the portable media tab my compact flash card is seen in there and Media player recognize it .Thinking that something might interfering with the install of the unit i re-formated the windows partition (not quick format) and re-installed windows. At that moment there was nothing else installed and all USB devices were unplugged. I tried then to install it and still no result. I then added SP 1 and tried it and again no success. After that i installed SP 2 and tried again . The result was the same again. I updated the bios and also tried anothe USB cable. I also tried on my laptop to see if it would work but that ...

A:Portable media player not recognized in XP

I finally brought the device to a repair centre in january and got it back this weekend. They changed the USB plug on the unit. They even left on the unit some songs,pictures and the video content on the install CD to show that it's working. I'm trying as best as i can to have it working with my desktop and laptop pc's but i still can't have it recognized by windows. Of course media player 10 doesn't see it .This thing is driving me nuts. I only get the mention that the MTP device is working properly in device manager. When i get to select which driver to install in the add hardware screen i have the choice of the one from the cd which is dated in 2002 and another one dated in 2004. I tried with both and still no results. As mentioned in my original post i have sp2 installed and tried various solutions for it like giving permissions to the everyone group in the registry. I disabled USB power management. If i can't make this thing work i think i'm gonna put it on sale on Ebay and let somebody else have the headache of making this work. The unit is working since they managed to install stuff on it . It seems to me that these kind of units either work with your computer or they don't. From all the posts i've seen on the net about these kinds of players i'm not the only one with this kind of problems. Frankly i will never recommend somebody buying one, they're not worth the hassle.

My HP Media Center quit working after updating with windows SP3. THen before that was resolved, I had a crash and replaced the motherboard and battery pack. Now my HP system recovery won't work so I had to buy another copy of windows XP media center 2005 to get the operating system up. It just loads as windows xp and I can't get it to load it as Media Center...not sure what I'm doing wrong. I read on the internet that certain service packs had to be loaded, but I get a message saying those can only be upgrades for Media Center computer. Does anyone have any suggestions as to what I've done wrong? My next step is to reformat the hard drive and start over from scratch, but not sure that will resolve my issue. THANKS!!

All of a sudden I can't reliably play any video media on my Win 8 64bit computer -- was working fine yesterday and AFAIK nothing (other than perhaps Windows automatic updates) changed. My first thought was to try and restore but even though I'm sure I created a restore point it tells me there isn't one. Sigh.

Okay, so then I try to perform a reset (but keeping all my files) and it tells me some files are missing and to insert my recovery media. All well and good, I actually have that (and know where it is) but when I insert the disk it tells me it is NOT a recovery disk.

It is, of course, precisely that -- a Windows 8 Recovery Media for Windows 8 Products 64 bit. I am running an official copy of Win 8 (well, 8.1, but I have no media for that since it was a free update). Yes, it's OEM (Dell) but that shouldn't make a difference. What the !#!%$! is going on here? And, more importantly, what I am to do now?

A:Windows Recovery Media not recognized

Be very careful, a reset will put your system back to a factory condition and remove all your files.

You might try running the Performance troubleshooter to see if it finds anything related to the video problem. Could it be related to sound for the video?

Is this video media a file on your system, a special type of file, on something from online and streaming?

Lately, when I plug in my CF or SD card to the computers media slots, I do not receive the familiar tone and they are not recognized. When looking under "Computer" they are not assigned any drive letter. I have tried numerous cards with the same results. And for the last year everything has worked fine.

However, if I leave the cards in the slots and 'Restart' Windows 7, then both cards are shown available and assigned a drive letter giving me access to all the photos.

So it kinda seems like some missing piece of the puzzle I just can't understand that is causing it to act that way. Anyone have any thoughts as to what I could look for?

Thanks. Jim

PS/ USB flash drives work fine when plugged in, sound tone, get assigned letter.

A:Media cards not recognized (kinda)

I think I solved my own problem. I uninstalled the drivers for the media slot then, upon reboot, it was recreated. Now working fine.

Thanks. Jim

Hello everyone..
Yesterday my laptop pushed a new Win 10 update, and all went fine, or at least I think so.
But today I see that my Sony WALKMAN - which I used with no problem until now, can't be recognized anymore.

Basically it just shows as (E or Usb Drive E: but when I click it it says "Please insert a disk into E:/" like there is nothing there.

Now the interesting part is.. if I go to Device Manager I see it and clicking on properties etc t says it's working fine.

But if I go to Disk Management, the Drive shows as 14 gb of unallocated space and it's greyed out.

However, if I put it on my brother's laptop, it works perfectly and it can be opened, music moved into it etc - it shows as Healthy - Primary Partition in Disk Management. So it doesn't seem broken...

It's the same on each of the 4 usb ports btw. But, other usb devices (2 phones, 1 tablet) don't have any issue and are detected.

What could have caused this? I tried the basic Disable/Enable in Device Manager and also Uninstall Driver.. It doesn't do anything, it appears back when I replug it in.

No change in Safe Mode and no change after sfc /scannow

If anyone has any idea I'd be happy to try anything to fix this..


A:USB device not recognized on my laptop but recognized in other pcs/lap

This problem is being reported by many forum members with many different USB devices. It seems that Windows 10 Anniversary is having problems properly recognizing certain USB drives and devices. So far, no one has come up with a clear fix for this issue but it sounds like it is clearly related to the Anniversary update. For the record, I did a clean install and have not had any issues but most of the people reporting this problem make reference to updating to Anniversary.

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.

Unfortunately I have tried to plug my usb HP pocket media drive model PD0000 but I get a message saying that it isn't recognized.

Thank you if anyone can help

A:USB HP Pocket media drive PDOOOO not recognized

With the drive plugged in, go to Start/Search and type devmgmt.msc Right click the devmgmt icon in the search results and Run As Administrator. In the Device Manager. If you see any devices with a Yellow mark or under Universal Serial Bus Controllers you see an Unknown Device, right click it and Uninstall it. Now unplug the USB HDD and restart the computer. A USB drive that is not recognized is usually due to inadequate power. If it comes with a Dual USB cable be sure to plug in both ends to the computer. Once the computer boots up, plug it into a different USB port, and not through a Docking Station or Hub as these ports are weaker. You should get a new hardware wizard. You may need an optional power adapter or plug it into a Powered USB Hub.

My HP DV6 is having...issues.  windows 7.  A bit of history: Recently (2 months ago) it quit installing Windows updates, and would download 3 everytime I shut down.  HP support could not help, nor did the Fix-It programs work.  Had to restore to factory defaults and that solved THAT problem. Recently tried reading camera card (which I have done before), but it did not read/was not recognized.  Today, tried to run a DVD, and when it didn't automatically start, I found out it isn't recognized. Tried HP Support Assistant, which told me the model # of the DVD drive I was using, then proceeded to say there was something wrong with the driver...and it couldn't fix it. More?  Explorer (windows, not Internet) will frequently time out or crash... I have Norton Internet Security with live update, and have yet to have any virus issues.  Any assistance or questions greatly appreciated!

I have an older Dell machine that I plan to use as a backup server for my family. It has 2 SATA HDDs, 1 IDE DVD drive, 1 IDE HDD

The SATA drives are recognized in BIOS. The IDE-DVD and IDE-HDD are not. Interestingly, when looking at the folder structure in Windows Explorer, all the devices appear. When looking at "Device Manager", all the devices appear. Everything actually functions when windows boots up. Trouble is, when powering on, the boot -screen tells me the Disk-3 and Disk-4 are missing. Then waits for me to press F1 to continue, or F2 to enter BIOS. If if press F1, windows fires up, and all works.
Trouble is, I want to schedule this to wake up on its own, run back ups, then shut off. I am learning how to do that, that is not the problem. Problem would be for the auto-turn-on, to be stuck in the BIOS screen waiting for someone to do something. That's a no-go for my intended purpose.

I have dillignetly gone through the "Master/Slave" configuration of the IDE drives. The IDE-DVD drive is Master, with a jumper, and on the end/black connector of the ribbon cable. The IDE-HDD is Slave (no jumper) and is attached to the middle/grey connector.

I have gone into Control Panel and eventually get into "Disk Manager". Here I see something that is perhaps the clue but I do not know how to rectify. The following is listed (and/or shown in the graphic panel of Disk Mgr):

A:2 IDE drives not recognized, 2 SATA drives recognized

You need to go into the Bios. The DVD cannot be Master. It has to be set as a Slave, if connected to the same PATA cable as the IDE, which would be set as Master. You could try the two on Cable Select. But you may run into problems, because of having also the two SATA units.

I have just purchased a Lite-On LH-20A1L dvd burner. However when I try to use any of the rewritable media I previously used with my old drive my burning software claims it's not rewritable so I am unable to erase it. I have tried Alcohol 120% and Nero 7.8.5 and neither recognizes it properly.

My curent configuration is:

CPU - Intel 6600
MB - Asus P5N32-E SLI

The new drive is SATA and the old was IDE. I have not yet tried pulling the previous burner from my old computer and installing it in the new one to see if that read rewitables properly but will do that next.

In the meantime does anyone have any recommendation on what else I could check?
(Edit - The same thing happens with my old IDE Plextor burner. 'This disc is not rewritable and therefore cannot be erased")


It tuns out Alcohol was actually causing the problem. If anyone enounters similar issues go into the Emulation options of Alcohol and uncheck the 'Ignore Media Type' box.

Ok, I will start from the beginning in order to try to give all necessary information.

I was given a used Acer Extensa 4620 laptop about a year ago when my PC went kaput on me. It had a 160GB HDD and the OS was XP. Well a few days ago I was cleaning out some old programs I never use because space was getting slim on there. No vital programs or anything (as far as I know). But I was also trying to install Nero because I was having burning issues with my usual DVD burning program. There were rumors that the version of Nero I was downloading had a virus on it, but most people said that was a false positive that virus scanners were pulling up because of the KeyGen.

Anyways.... the laptop slowly died on me. At first, it stopped loading completely. Anytime I tried to do anything with a Windows folder, the computer would freeze up and I would have to reboot by pressing and holding the power button. Then I started to notice that less icons in the bottom right were loading when I would reboot. I tried to run Spybot S&D and it ended up freezing. AdAware pulled up no problems. I ran Norton 360 and it did not find any viruses either. I then ran multiple disk checks and such because the laptop prompted me to because of the way I had to reboot. I knew there was something wrong.

Well, after a few of the bad reboots, I started to just get the "black screen with the blinking white underscore" issue that I have read about here. I decided that even though it would suck to... Read more

Hey I don't know if someone posted about this before but I couldn't find anything.

I've been trying to burn a few movies with Nero but everytime I put a DVD into my DVD burner, the Take Action screen that comes up (In windows XP), shows the DVD as being a CD, and Nero ends up failing the burning process because it thinks my DVD's are CD's

I've tried multiple DVD's and the problem still persists. How can I make my drive tell the difference that it's a damn DVD and not a stupid CD

A:DVD's being recognized only as CD's

Which version of NERO? Which burner? Which OS? What type of media?

Try this:
Cancel that dialog that comes up when you insert the disc.
Then, open NERO and click the media information or disc information button.
What does it say?

I've seen a couple of threads dealing with this problem, but so far none of them have had answers that fixed mine. So here's the situation, and maybe y'all know something I haven't tried yet:

Windows 2000 OS, 1gig RAM, one CD-RW drive, one DVD/CD-ROM.

One active HDD previously, 120gig Western Digital, fully set up and working fine. Jumper set on the middle pins to mark it as a master, on the end plug in the ribbon cable.

The new HDD is also Western Digital, 160gig, just bought, on the same cable with its jumper set to slave.

On startup, the initial information sees it and recognizes it as a 160gig drive, as Primary Slave. Both CD drives recognize as Secondary, and Primary Master shows up as the 120 -- no problem there.

Went into BIOS to check the settings there, and it correctly identifies type as Auto, not CD-ROM, sees the full size, etc.

But when I start up Win2k and go to My Computer to have a look, it shows both CD drives, the 120gig drive, but lists the /new/ drive as a CD-ROM -- clicking on it just makes it insist it needs to have a disk inserted. Right-clicking shows it as 0 bytes used and 0 bytes free, type Compact Disc. However, checking the Hardware tab in its Properties correctly lists WDC WD1600JB-00EVA0 under the other hard drive (WDC WD1200JB-00CRA1).

Add New Hardware detects nothing new to auto-add, and manually looking for it in the list turns it up properly as a disk drive with its full designation -- but telling it to check on it ... Read more

A:DVD not recognized

Sounds like a faulty drive.

Uninstall the drive in Device Manager and reboot. Aside from that, if one (ie: CD or DVD) is working, the drivers are installed and working properly. The drive is simply faulty.

Hi everyone
I'm having a serious problem with a ''USB NOT RECOGNIZED ERROR'' whenever i plug a
usb device into any of the four usb ports on my laptop. This started happening about a week ago
and i've since being trying all sorts to fix this issue. I'm using a laptop
Fujitsu siemens amilo li 1718
Vista home premium 32 bit
Processor - genuine intel(R) CPU T2130 @1.86 GHz 1.87 GHz
Ram - 1918 Mb
I have tried uninstalling all the USB ports and hub in device manger a million times and again and again in safe mode.
All the drivers on my mother board are up to date. I have created that registry hack in the regedit
HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb ----- 'DisableSelectiveSuspend and gave it a value of 1'
Uninstalled all the usb devices in programs and features which was a total of one. Again reinstalled all usb controllers and Hubs
in device manager. REBooted. Tried plugging in USB devices i have never used and still no luck.
It was suggested to delete the infcache.1 in windows or rename it to infcache.bak, rebooted and still the same problem.
I have also tried shutting down my laptop, unplugging the power and battery and letting it sit over night for two nights in a row but no luck there.
Uninstalled windows, deleted everything off the old copy and still the same.
I downloaded a driver wizard called DRiverWhiz to make sure all drivers were up to date and scanned the laptop. It came back with a few driver not
up... Read more

I have reinstalled windows twice since this problem started. One thing i just remembered now was that afew days before the problem happened i got an error starting windows showing a screen with all my devices and an error:

0271 - Check date and time settings
0251 - system checksum bad - default configuration used.

I assume you get this after you unplug the battery, i have never unplugged the battery since i got the laptop two yrs ago until after the problem as i was told to unplug it and leave it out for 30 mins.

Could this have had something to do with it?

Hi everyone, I have a problem with an A: drive. I have a gateway computer that is about 4 yrs old and it didn't come with an A: drive. There is an IDE connector on the Mobo and I took a floppy drive off of an older gateway and put it in this gateway computer I have...the computer is running WinME and when I boot up it doesn't recognize the drive. I went into setup and changed the setting to the appropriate type of drive and tried again. As the computer starts up I get an error that it is the wrong drive type?? In setup I switched the Floppy Drive A setting to 1.44/1.25 MB 3.5" and still there is no recognition. Am I doing something wrong? I used the FDD cable from the older gateway...the same one I got the floppy drive from. Any suggestions here guys or girls? Oh yeah, it shows up in device manager and when I click on properties it says it is functioning properly. ???? What am I doing wrong? Thanks again for your help.

A:A:\ not recognized??

Unlike IDE cables, floppy cables can be put on backwards. Make sure it is correct.

I just bought a 1.5 tb samsung story HDD and figured i would dumb everything from my 320 gb segate ex pro on to it. The seagate has sat in the same place for years with out being moved or anything, it has its own power supply and was plugged into the same port the entire time.

the seagate is not recognized and ive tryed updating drivers through device manager as well as the website (no help from website at all) drivers were up to date
would not allow me to use a perviouse driver

when i click on the drive letter i know it is i get the error : the file or directory is corrupted and unreadable...... now i know this is bad but the drive has never shown any sign of defect and has never been moved at all. I know there are ways to get data off of drives that are bad so i started doing some searching.

Some programs ive tryed are: partition wizard, EASEUS data recovery, pandora recovery, total recall data recovery

now a couple of the programs found the drives and didnt really show that there was anything wrong with the drive. and Total recall found the drive and was able to see everything but you have to pay to retreive your data. free version only alows one gig

Oh and ive also tryed computer managment>storage>disc managment

so i was wondering if anyone could help me with another way that i might not have tryed yet to get the drive to be recognized by my comp or if they know a free program i can use to retive and xfer the data to my story hdd.

I have a VIA VB7001 mobo with 1Gig stick of the ram recommended by Crucial. Issue is that the computer only reconizes a bit less than 500MB. Ran MEM test and the same thing (though on that same box). The Stick is 667 DDR2 (128 x 64). The MOBO User's Guide says the following:

"Due to the hardware limitation, DDR2 SDRAM chips organized as128Mb x 8 bank cannot be supported by EPIA with CN700 and CX700M2 chipsets"

Have I violated something to do with this user guide warning? I am running XP Home SP3.

VIA says the Dimm socket is for 533 (4200) but the 667 I have in there should dummy down shouldn't it? (and it does for half the capacity), Is there a setting I need to check to get full mem capacity?


A:Not all RAM Recognized!?!

What you have is an issue with high density and low density ram. Basicaly you can have RAM with differnt numbers of actaully chips on it. Lots of chips = low density and a small number of chips = high density. This was a big big issue back in the days of DDR RAM and I've never personally ran into it with DDR2 RAM. Connect Crucial and request that they exchance the RAM you bought for low desnsity RAM.

Hi, I have a "Powerdata" high-speed USB two hub plugged into a cord which is plugged into a USB port at the back of the computer.

Usually it happens after the computer has been running for a while, I get "USB not recognized" error message popping up.

I also get "device can function faster if you plug it into another port and hear our list of ports are available"

And when I have my speakers on I constantly get that sound that indicates you just plug something in or unplug something!

What would be causing it to do that?

I also have a "Centrios S. D. card reader/writer model number 441-5002 plugged into the USB hub.

It seems to give me all these error messages back and forth for awhile then it seems to stabilize again!? -- now it's doing it again!

I checked all the connections they all seem to be tight and he even plug them into different ports but it doesn't seem to make a difference.

What could that be?

Any advice please.... ?

I just installed my new DFI LanParty Pro875B board, P4 2.80C 800MHz CPU with Thermalright
P94 Heatsink and Panaflo 92mm fan, 2 sticks of 512MB OCZ PC3200/DDR400 Ram, Antec 550w
True Power PSU
HDD 80GB WD Caviar (Contained my previous OS WinXPPro and all data)
2nd HDD (not installed yet) 120GB Seagate Barraccuda

I previously had a problem with my MSI board and PSU upon boot just "dying" on me, so
ordered the above components to replace and upgrade as well.

After installation of all components out of and now inside case.
Boots up fine, I get the POST screen, hit DEL and get the BIOS
adjust BIOS settings, disable RAID (don't plan to use that) and Save, and no Windows!

Instead I get an error msg saying:
Windows did not start successfully and offers Safe/Last known good/ or Normal start up options.

I tried each of these options and each time, I get cycled back to Post screen.

I tried booting from Windows CD and it went into a Setup type sequence as if HDD was blank (?)

Why is my HDD with OS not being recognized?

Could I have lost my OS and data on HDD when I lost power with the previous PSU problems?

Any suggestions?

Hello. The power went out the other night while my computer was running. When trying to reboot now, the system can't recognize that it's there, not even a Windows boot disk. I put a Maxblast Powermax troubleshooting floppy disk in and booted to it and it recognizes the HDD just fine, even returns normal test results. It also say it can see that the partitioning table is fine.

Any way to fix this? Thanks in advance.
