usb hard drive disconnects WinXP
 
I've got a 500 gb drive that live in an enclosure. This worked fine on my laptop but when I plug it into my desktop, the OS recognizes it and I can access it for a short while but always disconnects within a few minutes. Any ideas on what the problem is?
TIA

What USB speed standard is the drive manufactured to? 2.0? 1.1? What are the USB ports in your desktop PC rated at? Most high speed peripherals will NOT work properly - or at all - backwards, i.e. faster technology towards slower throughput. It may be that your PC will require a high speed USB card to be added so that the drive can be used.

You might check your power management settings in the control panel.

Thanks, both the drive and computer are USB 2.0 and the power management settings say never to turn off hard drives.
I don't know what other setting to look for. WinXP is up to date as well.

Clutch, try this. Leave the drive on and plugged in. After Windows disconnects it, open up the Control Panel and select Install New Hardware. Tell Windows to search for any new devices. See what devices, if any, Windows finds. Allow Windows to "install" and configure the new device(s). Let us know what happens.

Does this happen on ALL USB ports on the PC or just one?

I had a Dell laptop that did this exact same thing and it was a bad USB port on the PC (Laptop)

You should also check power management in Device Manager for the USB hubs themselves.

I tried the "Install New Hardware" and was eventually led to the troubleshooting screens. I thought that would work, but nope.
It happens on all the USB ports.
Where do I check the power management for USB?

Control panel, System, Hardware, USB controllers, select one of them, doubleclick and then go to the last tab, i.e. Power Management.

Thanks, almost worked it made it further than before. I'm trying to copy several gigs of video files from this drive and with the power management turned off it made it further but it still failed.
It works on my laptop with no issues, I don't know what the problem is.

Clutch, it may be your USB cable. If you have another cable at your disposal, try swapping it for the one that's presently connected to the drive.

Thanks, but that's the first thing I tried and they both work fine with my laptop. I'm going to poke around the bios to see of there is a setting that needs setting.

Clutch, try updating the drivers for your USB controller and external hard drive. Also what service pack are you using in Win XP? Run a Windows update to make sure it is current.

You could also try this update from Microsoft that is suppose to improve performance on USB devices under XP.

Try to find a powered USB hub (one which plugs into electricity) and connect the drive thru it

Possibly the drive overloads the computer USB port untill it decides to shut down
