External HDD not recognized on USB 3.0 but recognized on USB...

Q: External HDD not recognized on USB 3.0 but recognized on USB...

An external hard drive works perfectly fine via USB 2, but USB 3.0 won't recognize the drive. It ignores it entireley. It won't even appear in the list of hard disks in Disk Manager, @Active or EaseUS Partition Manager.A driver issue? A h/w issue? Creating a partition on the external drive, creating and formatting a logical drive did NOT solve this problem with a brand-new drive designed to work via USB 3.0.Any ideas?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

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?

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

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!

Hello,

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 --------------------------------
REGEDIT4

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

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
-------------------------- 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.

Greetings,

I recently formatted my WD My Passport Elite from FAT32, to NTSF, in order to move files larger than 4 gigs onto it. I found that this new format is not recognized by PS3, and thus attempted to change the format back to FAT32. Instead, I decided to change the format to exFAT, which I found is also not recognized by PS3.

In attempts to format it back to FAT32, (square one *sigh*) I now have an external drive that causes windows explorer to lock up. When I plug it in, and select 'My Computer', it goes into 'Not Responding', until I restart explorer and unplug the drive.

In device manager, it does recognize the drive, but I'm unable to change anything from there.

Any suggestions on how to get my drive back, into a working FAT32?

I have an external Maxtor external firewire HDD that is exhibiting some interesting behavior.

When I connect the HDD to the computer, Windows recognizes the hdd, autoplay opens and the drive shows up in my computer and device manager however, the drive does not show up in disk management.

I therefore am unable to reformat or change the drive letter on the drive.

Occasionally, the Drive shows up in Disk Management as Unreadable. When it does this, saving anything to the disk fails due to an I/O failure

Any advise as to why it does not show up in Disk Management?

Hello, I have this problem: I recently bought an external enclosure that is USB powered I put in my HDD and when I plug it in on my computer it does nothing, the led just blinks once and that's it. I have checked on device manager disk management and nothing there.

I know both the enclosure and the HDD are good because I test them on my friends computer and the HDD is recognized right away within seconds, my friend suggest me to use the rear ports instead of the front ones but still same result, what could be causing my system don't see this device, everything else I plug in it works fine, I tried to disable usb legacy I disable another setting called EHCI but still same result.

any suggestions? Thanks in advance for the help.
 

A:External HDD not recognized

Hmmm....

1) Are you hearing the Windows device connect/disconnect ding-dong sound when you plug/unplug the USB cable? (can take up to 30 seconds sometimes i found)

2) When you say you checked Device Management, did you look under USB Devices and check if a USB Mass Storage Device appears/disappears as you plug/unplug the cable?

A few other things you might try
> Make sure you have the latest chipset drivers installed
> See How to Reinstall Your USB Controllers and Motherboard Chipset Drivers

You might also try connecting a self-powered USB hub to your computer (one with its own AC adapter) and connecting the drive to the self-powered hub. Or tryr a USB Y power cable to draw power from 2 USB ports for the device (like this one from Apricorn)

Just bought myself a WD Elements 640GB external drive.

Just took it out of the box it came in, plugged it in, and Win 7 doesn't recognize it. It doesn't show up in Disk Management, or as an available device to boot from. I've updated my chipset drivers as I've seen that fix the problem for others, but that didn't work. I've tried it in every USB port I have, to no avail. I've left it plugged in while rebooting, I've left my computer turned off for a couple hours and then tried, but nothing seems to work.

The drive is not dead, as when I plug it in, I can feel the disk spinning up when I hold it. The light that I assume should come on to signify it is working, does not.

So, any help/suggestions/sacrificial goats to make it work would be most helpful, as I'd rather not RMA it only to find the next one has the same problem.

Any ideas? there are no yellow flags in device manager its only 6 mths old. it worked at start and gradually just started not finishing the backup. now it doesn't work at all

A:external HD not recognized

It sounds like it might be broken. Have you tried plugging it into another USB port? Or into another computer? Some of these little USB hard drives can overheat and fail pretty easily. I haven't heard of Buffalo drives before so I don't know anything about their failure rate, but to me, it sounds like the drive itself is beginning to fail, if it hasn't failed completely already.

Hello there,

This problem of mine is somehow unique, as I didn't find anything on the web that solves this.

Recently I've upgraded from WinXP to Win7 ultimate. I have in my possession an external Verbatim HDD (500GB) that I use to backup my stuff.

When connecting the HDD the device is installed and you can see it in "My Computer" with the other drives.
After about 20 seconds, or when I try to copy data into the HDD, windows says "USB Device Not Recognized" and stopps displaying it as a drive.
In the Device Manager, I get the "Unknown Device" in the relevant USB port. Surely, I used all my ports to verify this issue.

As it appears, this only happens in Win7, not in previous versions of windows.

Can someone PLEASE help me get through this crisis ?

Hi all,

I've got a slight problem with an external hard drive - - WinXP won't recognize it. It's been recognized in the past, and one day... wham, it's not appearing in the list of recognized drives in My Computer, nor is it anywhere to be found in device manager. It's originally started happening when using the 1394 connection, so I switched it to USB 2.0 - - started working again, but a few days later, dropped off the map. Again.

Really frustrating, and I've got no idea what's causing it...DM doesn't list any malfunctioning host controllers or drivers, so I'm open to suggestions.

I keep two external drives as backups (ok, maybe overkill, but 40 years in IT makes me uber-cautious), both 500GB USB 2.0. I use a USB hub for them, printer, flatbed scanner, etc. Clicking on Win8's 'computer' to see connected devices will initially ONLY show ONE of the drives - I have to disconnect/reconnect one of them to suddenly get both recognized. Why? They have different names; never saw this problem in XPPro.

A:External usb hd not recognized

If I understand you correctly, the drive is shown in device manager. Try going to Disk Management and see if it shows there. If it does, right click the drive, select 'change drive letter or path', next screen select add, give it a drive letter from the dropdown menu. If it wants to initialize and format the drive, do not do it, you will lose all data on the drive. To get to disk management, right click computer, select manage, then in the left column select disk management.

Also, on external devices, I give them drive letters high in the alphabet such as X or Y. That way Windows is not likely to assign another device that letter.

I've had a WD My Book 2.0 500gb for about 6 months now and it has worked perfectly fine... no funny sounds or anything. Well, today I reset my computer and unplugged my external while doing this. I did not think it was a big deal, but when I went to plug it back in a few hours later it was not recognized.

At first, the blue indicator light was on so I looked under Disk Management and Devices but it was not there. Tried 2 other USB ports and then I unplugged the HD from the power strip, let it sit, and replugged it. Blue power light flashed and did not come back on... still no recognition. I then tried it on another computer and it was not showing up either.

Next, I googled around some more and I went through various booting and rebooting sequences and made sure Plug and Play is activated. I am pretty clueless here... the only thing I can think of is that I fried the power switch in the case. I can't imagine I corrupted the data or anything else by unplugging it without ejecting first, or through the reset. But, before I open it up and void my warranty I wanted to check if there were any other ideas or things i could try.

I am running a brand new computer with XP SP3, and a EP35-DS3L if that information is relevant.

Have you tried inserting both USB cables? Most, if not all, external harddrives have data cables that have two USB ports. The fatter cable is supposed to be for power and data transfer. The thinner cable is for backup power.

edit: If that does not work, you could also try inserting both cables and restarting your computer. That process has not failed me once.

Hello All! I've been searching for an answer to my problem for almost 2 days to no avail, I really hope you can help me...

A few days ago, my WD 1TB stopped working. Ironically, I was trying to back up my back up onto another external when it stopped and gave me an error message, which I can't remember. Now, when I plug it in to my laptop, it doesn't work.

Here is what I mean:
-No sounds are made on my laptop, indicating that something has been connected to the laptop.
-It doesn't show up in Disk Management
-It doesn't show up in Device Manager either

This is what I have tried, but has not worked:
-Using a different USB power cable
-Connecting it to another laptop/PC (it won't read on them either)
-Cleaning out my "hidden devices" in Device Manager
*I cleaned out everything I could under volumes and USB controllers. Rebooted twice and reinstalled everything. It still didn't work.
-Connected it to different USB ports on my laptop

Other information:
-When I connect the HD, the light will come on and will sound like it is working, but there are some definite "clicks" that I don't remember happening before this problem.
-I'm pretty sure that it used to show up in Device Manager under WD Drive Mgmt. devices, but it definitely does not anymore. There isn't even a "shadow" or hidden version of it.
-Win 7 - clean
-Hd is about 2 months old

I removed a laptop HDD and put it in an enclosure, connected it via USB to a PC, and accessed files on it without problem for a couple of days. Now it does not work.

When it is connected to the laptop:
The BIOS doesn?t list the HDD as a possible place from which to boot. Further, I cannot load the computer anymore?the screen goes black and white text comes up. It says:
PXE-E61 Media test failure, check cable
PXE-MOF Exiting Broadcome PXE Rom
Operating System not found

When it is connected via USB to the PC:
It does not show up in My Computer
Device Manger lists the laptop HDD under Disk drives as as ?generic void disk USB device?
Device Manager also lists it under Unviersity Serial Bus controllers as ?USB Mass Storage Device?
Testdisk does not recognize the laptop HDD.

On my PC, I have tried a number of troubleshoots:
-Uninstall device and then replug it in (in Device Manager)
-Ran drivecleanup and cleaned out about 19 USB drivers
-I cannot fix it in Disk Management; the drive does not appear.

The only thing I can think of is that I unsafely removed it from the PC. It had this recognition problem a couple days ago, but restarting the computer solved it. Now nothing will.

Thanks in advance!

Sounds like the drive might be on its way out. Test it out with one of these utilities: http://www.carrona.org/hddiag.html

Hello,

I have a 1tb WD external hard drive. It worked fine up untill yesterday. When I pluged it to to some new computers at work, the computers will recognize the drive and begin to auto install it. Then I get the message saying "Your new hardware is ready for use". But then, its not visible in my computer nor can i see it in disk managment. I am using windows XP. Any help would be great.

Thanks
Jeff

BTW I have only used this drive on one other computer and it worked fine. Now, it wont work on any computers. I cant try it on the laptop it worked on before though. Also i have tried diffrent USB cables and still no luck.

"I cant try it on the laptop it worked on before though."

What does this mean? You no longer have the laptop or what?

Does it have a power supply or USB ps dongle?

What do you mean by "the computers will recognize the drive and begin to auto install it" - p&p just makes the alert noise and there it is! What's to install?

I have a Smartdisk Crossfire 160 external hard drive. Today my computer decided not to recognize it. I believe I am using a firewire cable (I'm still not sure how to tell). I have turned my computer on and off, switched ports, the power is on with no strange sounds, but it is nowhere to be found on the computer.

What is my next step?

Any help would be greatly appreciated!

I would first try System Restore to a date when it was recognized...first thing to try.

My Seagate GoFlex 500 isn't showing up in Windows. Disk Management sees it, but there's no feasible option there. It's not a blank drive, so I can't make a new simple volume, only delete it.

I have important data on there. What gives?

A:External HD not recognized

Hi there
If it's properly formatted and you can SEE it in disk management simply Right Mouse click on the disk and then choose assign (or change) drive Letter. Choose one from the drop down and after a few seconds the computer will recognize the device.

Sometimes especially if you switch drives between machines this happens -- it can be caused by the "Disk signature". There is a way of changing this -- I can't remember the link and I don't bother -- just assigning a volume letter is simple enough so that's what I do.

Cheers

I have a new XPS 8920. I bought a WD 4TB drive that I put in an external enclosure and plugged into the USB port. The drive can't be seen in File Explorer. I opened Disk Management, and see it there, but it's only showing 1.69TB. See Below.
In researching, I was told to update my Intel Storage Driver to the latest, and reboot, and the full 4TB should be recognized. Well, going to the Dell support site, I downloaded the Intel Storage Driver for my system, but everytime I try to run it, it fails. (See Below) 
What do I need to do to get this full drive to be recognized? Thanks.

I'd suggest you install first the Chipset drivers in your Dell Product Support page and then try to install Intel Rapid Storage driver again.

I bought an external disk drive about a month ago for my laptop, and it has worked great up until now. When I plug it in it turns on and functions normally, but my computer doesn't register that it's plugged in. I'm not sure what the problem is with my computer and why it doesn't show that the drive is plugged in. I would like to know if there's any way to fix this with my computer or if it could be the external drive that's causing the problem.

Test the drive on another computer. That will confirm if you have a drive or computer issue.

A:External HDD is recognized but there's no folder

Hi Pam and welcome to TechSpot.

What kind of external HD are we talking about? Brand and model would help along with the type of interface, assume it's probably Usb2 but still need to know for sure. When you say it is recognized does this mean you can see it in Windows Explorer and if so, does it have a drive letter assigned to it? That should be enough to get things started.

I have the same problem. I am running windows xp pro w/ sp2. I got a new hard drive and an external case. I hooked the new hard drive up directly to my pc to initilize it and format it. I then removed the new hard drive and installed it into its case. I do not see it under device manager or disk management. When I turn the new external on, I do not get the little sound or message that it recognizes a new mass usb storage or anything. If I hook up an older external, it boots up fine. I initialized the new one as basic and partition. It is formatted as NTFS instead of Fat 32 like my older one but that is the only difference I see in the 2 drives. I do have USB 2.0 ports. It is securely connected in the case. I got a Ultra case from Tiger Direct. I wanted a case with the fan. I had problems with a Seagate external overheating before. I am sure there is something simple to this. I just don't know what I am missing.

I have a Seagate external 250 drive . Lately, for a reason I cannot determine, my computer stops recognizing it and I cant access any of the 100 plus gigs of information i have in there. I disconnected everything and reconnected it, and it recognized it again. Now, 5 days later, it happened again. Does anyone know these symptoms and what i can do about it? Thank you.

This afternoon I plugged in my external hardrive, and the familiar autoplay options popped up. I accidentally clicked on use media player to play files. Realplayer was taking a while to load, and I didn't want it open in the first place, so I attemptd to close it, and meanwhile clicked on the My Computer link, to view the files that way. I got the non-responding message for real player, so I did Ctrl Alt Del, and hit end program. It still wouldn't end, so I finally just closed my laptop, in an attempt to put it on standby. It didn't go on standby, until after I reopened it. Somewhere in there I had pulled out by external, because it is the kind you don't need to click on safely remove harware. Eventually my laptop was running fine again, and I plugged in the external, and it told me I had put in new hardware and asked me if I wanted to search online to install it. It wasn't new hardware, so I unplugged it again and restarted my laptop. Now it won't even recognize that it's there. It does see that my flash drive is there, so it's not the USB ports. I tried to use my external on my home computer, and it didn't recognize it either. I have a lot of files on there, and I don't want to lose them, I was wondering if there is a way to have my computer recognize my external harddrive again...

I was playing a game online with my friend and decided to use my gamepad to see if I'd play any better.
I had no room to plug it in. The front USB ports had my Nintendo Wi-Fi USB connector and my external drive, and the one in the back had my old external drive which I had kept plugged in to move files from it.
So I unplugged the USB connector and plugged in the gamepad and anything I had open that was on the external drive froze. I panicked a bit and hit reset and unplugged the gamepad. Then after rebooting 3 times I plugged my wifi usb connector back in, reinstalled it, unplugged my external drives and plugged the one with the problem in the back, and plugged my gamepad into the other port on the front.

Now everytime I turn on my external drive it just says it can't recognize the device.
I've tried plugging the external drive into all 3 ports, I've tried undoing the installation in Hardware, I've done everything I could think of. It works fine on my other computer.

Don't know what model my external drive is, the only things on the label are serial numbers or something. It's a white-ish rectangle with black cousion things on the end and a big black PHILIPS on the top.

I think the problem started when I plugged the gamepad in, not when I unplugged the Wifi USB Connector.
