I upgraded my computer from an ECS k7s5a MB with 2000+ cpu to a Asus KT600 with 2600+ cpu and went to a antec sonata case. Now my hard drives are being problematic. At first, I couldn't even boot past the bios, so I formatted drive c: (40 gig seagate) and put xp pro back on. Then drive d: would not work either(200 gig WD), and was identified as a RAW file system drive and even partition magic 8.0 would not help. After a while, drive f: came out of no where and it is actually what used to be d: and it is totally accessable and works fine, but d: is still a strange RAW disk that is inexplicable. I turned off my computer and disconnected my 200 gig drive and rebooted and drives d and f dissapear. When plugged back in, I have drives c, d, and f that are hard disks, but can't get rid of drive d and don't know what it is even. I had used partition magic on the 200 gig drive previously but had undone that and it was only one partition before I installed the new hardware. So, I thought it may be some remnant from part. mag. that was being identified as drive d, so I formatted the 200 gig from the disk manager(which sees only drives c and f by the way) but drive d is still listed when i go to my computer! When I click properties for drive d, it says, file system is raw, used space, free space and capacity are all 0 bytes. Please help!
