Ok so i had a raid 0 setup with 4 HDs. I was running XP and went to format my Hds and put win 7 on my PC. i took out all but 2 changed the raid setup in the bios to 2 drives and now it says all HDs are bad or damaged. So what is going on? I turned off raid and have gone through 5 HDs and it says all are bad HELP PLEASE. It wont let me even put XP back on just one Hd. SYS is SIG.
