I've plugged my 40Gigs to the serillel adaptor (I've a cute NF7-S 1,2 , bios 20 recently updated, SATA driver 1.0.28) and after installing Win XP Pro on it, SP1 and nvidia 2.03 drivers i hear some "clocks" (yes, say "clock" and that's the sound!) They hang the PC at all....I've already low formatted the drive, thinking of a BAD SECTOR problem.... Nah! The same...after reinstallin everything. Can anyone help me? Thanks....
