A few questions ?

Have you tried using it in other USB ports ?

Is it plugged into a hub, into a socket on the board, or into a powered USB hub ?

Does it work OK on another PC ?

Does your external H/D have its own power supply ? i.e. it is a 3.5" one, or is it one of the USB connection only 2.5" drives ?

Have you, at any time, unplugged the drive without going through the "Safely remove hardware" procedure? This can easily cause the death of a hard* drive if disconnection is done whilst the drive is reading or writing.

*Or any other drive.

If your drive is a Seagate, I believe that XP may have automatically downloaded and installed this Cypress at2lp driver. It is apparently what causes the problem, so if you do as set out below - it should fix things.

Control Panel --> System --> Hardware -->

Device Manager --> Universal Serial Bus controllers

"cypress at2lp" should be at the top of that list

Right click it --> Properties --> Driver --> Roll Back Driver

And if the external hard drive in question is plugged in and turned on, it should be immediately recognized and reappear right after the rollback is completed.

Then make sure you adjust your Windows Updates to ignore and not install this driver again.
