I have been called in to "fix" a 2000 server.  It had been set up with a software raid (no, I don't know why) but I have had to replace the system HDD and reinstall the OS.
Is there any way of recovering the raid?

Not by the sounds of it.  If it was a mirrored RAID you could have boot to the mirrored copy, broke the mirror, and then rebuilt the mirror.  Sounds like it might be too late for that.  Also with mirrored RAID if the OS gets corrupted then your mirror will also become corrupted.  You may still be able to pull the data from the second drive.

Thanks for your reply.
The system disc was not part of the raid, it was only data stored on the raid.

OK then you need only replace the drive then rebuild the array in the console.

PS you do not need a fresh Windows OS install for this.

I think I am now back to the original question.  How do I rebuild the raid without loosing data?  The 2 raid discs are not damaged but the new installation of the os does not recognize them as even a broken raid, it says they are unformatted.

OK I get you know, sorry I thought the RAID had a bad disk NOT the system.  Please tell me they had good backups.......if not you could attempt a recovery with ON-Track software or a data recovery service.

You never mentioned what kind of RAID... RAID 1?  RAID 0?  For a software RAID, you'd have needed to import the disks (they would/should have been considered "foreign").  If RAID 1, Partition Table Doctor might have been able to recover the partition table and allow you to pull in the data... but that's not free... so either you would use backups or TRY to save time PURCHASING a product that could POSSIBLY recover the data.
