I have a related post about a BSOD after a Windows Home Server restore, but I seem to have a more basic problem. I added the new drive as a second drive but when I go into the bios to activate it, it does not recognize this new drive. The old drive is a 160GB Seagate SATA drive that came with the system about 6 years ago.
The odd thing is that WHS seemed to have no trouble working with this drive when it ran the restore. I have the original bios A01 - do I need to upgrade it? It still begs the question of how WHS was able to make it work. I also downloaded and created a bootable CD with data lifeguard software and it could not find a WD drive.
Tonight I removed the new 500GB drive and connected it as an external USB drive. The new drive contained what I expected - a restored image from my original drive thanks to Windows Home Server (WHS). So here are my conclusions:
There is no need to update the bios because WHS was able to write to the new drive with the current bios
Starting over by doing a fresh install of Windows XP is likely not an option because the bios doesn't recognize the drive (I tried both RAID/AHCI and RAID/ATA). In any event it's not a desirable option.
The new drive is functioning fine.
So the question is this: what did WHS server do to allow the drive to be recognized and written to that is not in place now on my PC?
