I just bought a Western Digital 200GB 8mb cache drive (WD2000JB). When I first installed the drive, the BIOS only saw it as 128GB, as did WinXP so I updated the BIOS and it then found it as 200GB. I restarted and used the utilities that you can download from there site to partition and format the drive into 2 drives, 110GB and 75GB. It partitioned and formatted them fine, even WinXP saw them as the correct size, etc. but when I copied information onto the drive, it gave me an error and said the directory that I was using is no longer available. I rebooted and got all kinds of checkdisk errors (it said it fixed them) and the directory I had just copied was still there, but alot of the information isn't there, and one of the directories says its invalid or not available, and one of the partitions says it isnt formatted now. I read a few posts saying that the retail version came with a ATA card, but since I just bought the drive only from newegg.com I didn't get one. Is it possible that my slightly older Abit KG7 motherboard cant handle this, or might I just need a new ATA card? Im running Windows XP Pro and all the drives are NTFS file system. Does anyone have any ideas or suggestions?
