Moving an IDE RAID0 from machine to machine

I have an Epox 8K3A+ with a HPT372 RAID controller and two WD40bb IDE drives in RAID0.

What would be invovled with moving these two drives to another machine with a HPT raid controller (on the motherboard) and having them recognized without blowing away the data? Would it be possible to move them to a motherboad with a different hpt controller like an hpt374 and have them recognized (while avoiding the chance of acidentally destroying them in the processes?)

Has anyone done this???

I'm thinking of building myself a new system and giving my current one to my mom (minus the raid and a few other components.)

 
I think there's a "rebuild array" option in the controller's BIOS, usually accessed by something like ctrl-H when it's detecting the drives. I've only had one RAID capable board, and I didn't use it long since it kept losing the array setup (RAID onboard wasn't perfect by then). But the rebuild array option is something I just saw in some post somewhere. 🙂

This may require that the controller be exactly the same (SCSI drives require that you format the drive on the new controller anytime you change it). You really should make a backup of your system before you do something like this (a good idea even if you're just switching boards without RAID).
 
Unfortunatly I don't have a practical way of backing up the 80 gigs of data on my RAID.

As far as SCSI RAID, you can move them from controller to controller without any problems ... at least as far as Dell PERC controllers go. They store the RAID config on the drives and another Dell PERC (Power Edge Raid Controller) can just load the config from the drive and use the RAID. I've done this a number of times but haven't ever had to do a similar operation with IDE ....



 
Well, moving from one SCSI controller to another of the exact same type may not matter. Moving to a different type, you probably need to format the drive for that controller. I haven't used SCSI for hard drives, this is just what's suggested in every SCSI information page I've seen. I was also only referring to the file system formatting, not the RAID configuration. Again, going from one type of controller to another, you may need to rebuild the RAID array, but since it's IDE, there wouldn't be a need to reformat as long as the array can be kept.
