I have a 1tb Seagate external hard drive hooked up to a pc (usb) running win xp and when i try to "safely remove hardware" it always says "cannot stop 'generic volume' right now. please try again later". .... well I've tried again later, many times over the course of several weeks and it never works. it has worked just fine to "safely remove hardware" on my laptop running windows vista. Also, the drive is pretty new (about a month old) and I've been sharing it over the network so my housemates and i can all share movies, but Ive started to hear the clicking. I stopped sharing the drive and noticed the clicking decrease in frequency (maybe 1 or 2 times a day when I'm around whereas before it would be around 4 to 5 times a day) ran Seagate's software to check the health of the drive. Two of the tests checked out but it said the S.M.A.R.T. test was unavailable. Any ideas?
