Im running an awesome western digital essentials 320GB USB hard drive its great i leave it plugged in all the time on an always on PC
its really great and the drive stores every picture and mp3 i have.
when trying to do some maintenance on my music collection i noticed that some folders wont delete, it says something about it being in use at this time.
occasionally if i keep jamming away at the DEL button it will eventually be removed (trying every ten mins or so)
ive checked the security tabs and there is no restrictions in place for this drive and i have no special drivers
for it or any other unusual security features.
its an irritation now its been going on for about a yeah and now i have lots of empty folders.
