Hi,

I purchased 80 gb external hard disk, it is working perfectly for four months, but after that it when i connected it to my PC then it says "The drivers are not installed for this DEVICE code (28) ", I reinstalled the drivers through Hardware wizard but it says " There was a fuction driver missing for device instance ".

the path came as "c:\winnt\inf\usb.inf"

Please help me to save this little deviceUnplug the external drive after powering down.
Re-boot.
Go to CONTROL Panel/System/Hardware/Device Manager.
Right click ALL INSTANCES of USB Roots and Hubs and select remove.
You will get a warning message...ignore it.
When finished re-boot the computer a few times.
Then power down plug in the USB external drive and re-boot.
Is it seen now ? ?I do not see remove anywhere , is it disable or uninstall ??
Uninstall.....sorry.tried many times but no use, same problem re appreas again and againWhat version of Windows ...and do you have a CD ? ?If this is windows 2000 TRY installing service pack 4.
