Let me rephrase: how do I setup SATA RAID 0 in Debian?

Were these set up using a hardware RAID controller? You may need to plug
them into a controller of the exact same model to get to the data. The
on-disk format is frequently not interchangeable from one RAID
controller to the next.

Hm. This sounds bad as it was a builtin motherboard controller - Via maybe? Don't have it in front of me. I'm not even sure if it was a hardware or software RAID because Windows required drivers to see it, and (obviously) I never mounted it in Debian. This is a very humbling experience indeed...

I suppose you could attempt to set up a Linux software RAID and present
these drives to it. I wouldn't count on it working, though. The Software
RAID Howto is a good place to start:
http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html

Thanks for the link! It seems a bit outdated (like so many HOWTOs), and I can't tell if any of the instructions would work for "importing" an existing array because of statements like the following: "This should initialize the superblocks and start the raid device." (section 5.5)

Basically, I want to be able to mount 2 NTFS formatted disks readonly as a RAID 0 array with 64kb chunks.

Thanks, for the help!

It seems strange to me that Windows would require drivers to see it. I mean, on this machine, the CMOS has to be configured to "Boot to SCSI" to use the RAID as it's primary drives. Whether or not it boots to them, Windows can see them - driver or no driver. Perhaps the RAIDs are different, somehow?

What this RAID came with was software to allow you to reconfigure the RAID after startup. Useless piece of fluff, if you ask me.
