I have a pair of external hard drives that are used as storage for my home
network, both of which worked just fine in XP, but have only worked once
since installing Vista on my computer. I don't know how they actually ended
up working, but I since restarted and went into XP to finish up some things.
Since then, I've gone back to Vista, with no luck of either drive showing up
and being usable. I'm thinking of just going back into XP for a while until
theres some sort of fix for this, because I need those drives working. Anyone
have any ideas?

PS: I can't find any trace of the external cases even being found, no
"unknown device" messages or nothing. Just quiet, no idea if they are being
found or not.
