RE: Cannot detect external USB hard drive
Hello Carlos,
THe infcache file is not regenerated on Windows Vista. So if you delete
it, for all device installatons you will be prompted for the locations of
the device drivers.
You will need this QFE to be able to resolve the issue.
940199 Error message when you try to install a new hardware device on a
Windows Vista-based computer: "Windows encountered a problem installing the
driver software for your device"

Thanks,
Darrell Gorter[MSFT]
