Hi. Athlon 64 3400+, 1gB RAM, 500gB HDD, Abit M/B. I've cloned my 160gB SATA HDD to a new 500gB SATA HDD using TI 9.0 Workstation by connecting the two via SATA. Both drives recognized inside Windows XP Pro. I used the Seagate Disk Wizard Utility to introduce and prep the new drive. TI went through without complaint. Swapped them at the connectors on the mobo. Thought I had it knocked. However when I go to backup the new drive, I'm getting Bad_Pool_Header stop code 19. Never had this with the old drive. So I'm attempted a Repair Install using my WinXP CD media. The mini-Windows environment starts up fine, but then it tells me it can't find any HDD attached to my system!!! What? It boots up fine, reads and writes to the new drive, shows all files/folders in Explorer, etc. etc. Luckily I haven't put much on the new drive since I had this problem right away. Is there something in the mysterious SATA setup business I should have done beforehand? That's the only thing I can think of at this point. Is there any way to recover from this mini-disaster?
