yes bro iam having the same prob as you do.........
now having spet so much buck i dunno who is to blame wd cavilier green or windows 7.... or my self...........
now iam going back to my vista ultimate and cross my finger it works.
differently i have to go for xp service pack 3 ....for the time being iam just tearing my hear and kicking my ass
oopse one more thing anyone who wishes to install windows7 must know ...it is not compatible with various soft like nero / firefox ....and the list goes on......belive me you wouldnt know whether to scratch your watch aur wind your ass imean u would be confused
