Windows vista SP2 not reading USB hard drives

[Jaysee]

Having problems getting vista to read my USB storage drive. Some work, some do not. Unfortunately my primary does not. This began with the update for SP2. Ive been reading and have deleted the Infcache.1 file to force windows to rebuild the file in hopes that it finds the drive this time however no joy. Obviously this is a bug with the newest Vista. Anyone have a no fail fix for this?

Thanks

What hard disk is this? Have you also made sure the drivers for your motherboard are updated?
