I'm not sure exactly of the issue. Is this a harware RAID controller?
If so, the operating system should have nothing to do with the rebuild.
It's up to the card.
Also, are you running two physical volumes? You mentioned
re-installing SBS2003 from scratch If you wiped out the previous
installation of SBS and were using the RAID-1 volume for data, the data
may not be recoverable due to NTFS and/or encryption credentials that
were lost with the old server installation.
Data corruption would be promptly mirrored in RAID 1. Furthermore, a
corrupt file would be nicely saved (and parity distributed) on a RAID 5
volume. I don't know of any RAID controller that would check all of my
EOF markers and Microsoft Word formatting data. Corrupted _files_
should not cause an entire volume to be unavailable.
As for the new 250GB not wanting to replace the old...can the drive
manufacturer verify the actual size? If the replacement drive is
smaller, the RAID volume won't rebuild. For instance if you have a
251&249, it won't work. If you have a 249&251, the 251 will be treated
like a 249, and you lose the leftover space. If the drives are
suitable in size, your "good" drive may have damage beyond file-level
corruption.
If your RAID volume is data-only, the OEM's suggestion is valid. Get
the data off of the questionable drive.
"Talk to legal" is telling you that they have no obligation to protect
your data. They are obliged to provide you with working hardware if
your current hardware fails. It is up to you to test the configuration
for your purposes and maintain proper backups.
If you are still having trouble with data recovery, labs like OnTrack
are worth every penny. I've spent thousands of dollars on a few jobs
to get important data that would have cost untold hundreds of hours to
replace. Evaluation should run you around $100-250 depending on the
media and drive configuration. We had one disassembled in a clean room
and raw data streamed off it it. They re-assembled the drive so we
could return it for a warranty replacement.
Hope this helps.
