I moved my 40G Maxtor running XP Pro from an old P2 system to a new P4 system. BIOS detected it, but wouldn't boot -- gave me the "disk read error".
I put a Seagate into the same system, booted up fine. Windows saw the Maxtor, no problems. Using Casper, I cloned the Maxtor onto a partition on the Seagate --all the files are there and fine. I did an "upgrade" install of XP onto that partition, and am able to boot using that partition. So I attempted to do a clean install of XP onto the Maxtor, but I never made it past the setup process, because I'm still getting a "disk read error". Casper said the MBR on the Maxtor was good, but I rewrote it anyway, but that didn't help.
I'm about to pop in the Maxtor CD and repartition the HD and just start from scratch. But if anyone has a better solution, I'd love to hear it!
