External USB Hard Drive Not Recognized in XP?

By longhorndkr ·
Help anybody,

My laptop HD burned up and I got a new one but the old one was under warranty so I bought a drive enclosure for $20 and use it as a backup drive of 80Gig. The enclosure came with a USB connection, etc. It used to work (come up automagically when I would plug it in), but I had some work done on the laptop at CompUSA and now when i plug in the USB cable it says Unknown Device.

I've scanned for hardware changes, tried to use other Toshiba drivers but no joy. How do I get XP to recognize the drive???

Thanks,
Dave

what did comp usa do???

Actually, when I first read the title of the post I thought that SP2 wasn't installed on XP. Did compusa have to reload the operating system? What did they fix???

Truthfully, take it back to Comp USA and tell them to fix what they broke.

RE: External USB Hard Drive Not Recognized in XP?

Well, without getting into a long story, my motherboard had to be replaced. They didn't have the type I needed so I had to ship it to California to get replaced.

The hard drive was always fine, I've got the latest Service Packs and a new motherboard, I guess. It seems to read that something is plugged into the USB but doesn't have the driver. I do not believe my external hard drive came with a CD or driver but I see others for sale online have them so may try to download drivers from one of those and give them a shot.

If they replaced the board

by DanLM In reply to RE: External USB Hard Dri ...

Then they most likely had to reload windows. Orrrrrrrrrrrrrrrr, windows does need to be reloaded. This from past experience way back when. God, I use to fry a board once a year. But, every time I did I had to do a reload of windows.

I don't think its the external drive, I think windows is fuggered. Have you tried other usb attachments... ???? Do you have issue with any other hardware?

I wish someone else would chime in here... I hate telling anyone they have to reload windows(oi, reformat and all that crap).


Hmmmm, thinking about this. Ok, replaced the board. Did they load all the drivers for that board(usb being one). Did they give you the driver cd for the board. hmmmmm.... If they did, one thing you might try is go to (my computer, right click-----hardware, device managers) and delete out the usb from the device manager and load the driver from the motherboard cd. Actualy, if you rebooted it should reconize it as new hardware and ask for drivers.

hmmmm, im shooting in the dark here. Again, I wish someone else would chime in here.

Uninstall USB drivers and do a Power Reset

by Macgyver.Hicks In reply to If they replaced the boar ...

I suggest going into the device manager and uninstall all of the USB Host controllers. Once done, turn off the system, disconnect the power (A/C & Battery) then press and hold the power button for 30 seconds. Reconnect the power and boot the system.

Sometimes, there can be transistors switched the wrong way in the hardware and that can corrupt the drivers. By doing these steps above you clear corrupted drivers and circuits. When you boot back up, Windows will reinstall clean drivers.

As well, you may want to see about updating the chipset driver and BIOS for the new mobo.

This has worked for me in the past.

must initialize drive first

by obfyouth In reply to External USB Hard Drive N ...

With external drives, you often have to initialize the drive first in WinXP. Here are the directions for how to do that:

Reinstall USB

by bhatnagar_nitin In reply to External USB Hard Drive N ...

you need to reinstall the USB flash driver.
For this, go to "Device Manger" tab from "My Computer properties"
Check for the USB host controllers. Remove all of them and then press F5 or refresh button. The host controllers and USB will be detected again. Now try removing USB safely from the wizard.

Also, You might try going into add/remove programs, uninstalling all USB storage-related drivers, then going into the registry and deleting all of the subkeys under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR
Then reboot the system, install only one removable device driver and try connecting/disconnecting only that one
device.

Hopefully it will work.
