I haven't seen anything like this posted anywhere, thought I'd put it here in case anyone else is interested.

These are the steps I took to move a Windows XP system from 2 IDE (PATA) HDs to 1 SATA drive (500GB). The Win XP system consisted of a 60 GB C:/ drive, and a 150GB drive partitioned as E:/ and F:/. All partitions formatted FAT32. This was a NON-RAID setup. Mobo is a Gigabyte GA-EPC5C-DS3R.

1. Install new SATA drive in machine to existing open SATA connection.
2. Boot into BIOS, make sure SATA mode was set to "IDE" (If you aren't setting up a RAID system, this should insure that WinXP can see it without any problems)
3. Save changes, restart.
4. Boot into WinXP, make sure new drive is recognized. (Mine was)
5. Restart
6. Boot using SystemRescueCD
7. Start up GParted
8. Copy C:/ partition to SATA drive, expand it to 100GB
9. Copy E:/ partition to SATA drive, expand it to 300GB
10. Copy F:/ partition to SATA drive, expand it to 100GB
11. Apply changes in GParted
12. Wait until everything's done.
13. Set new C:/ partition to "boot" in GParted.
14. Shut down system, then disconnect all old drives.
15. Restart, and cross fingers ;-)

Final result - WinXP rebooted with no problems whatsoever. I did have to go into Drive Manager and redefine the 2 new E:/ and F:/ partitions appropriately, but after that, I was done. Hope this helps someone who's a bit behind the curve in HD technology (like me) upgrade.

if XP has the sata drivers, if it's not it won't work
