Setting up ATA RAID 0 on existing installation

[Andrew Konosky <TerranAce007@xxxxxxxxxxx>]

I recently upgraded to a Western Digital 80gb 7200rpm 8mb buffer hard 
drive, but it ended up being defective and crapped out on me after only 
a day. I sent it back, but the RMA process was going to take two weeks, 
so I went to Circuit City and bought myself another one. Well, the 
online store would'nt refund my first drive and I just got my 
replacement via FedEx a few days ago. I have already setup and installed 
by dual-boot system with Windows 98SE and FC2 on the second drive, and I 
don't want to have to reformat and reinstall everything again. Would it 
be possible to setup a striped RAID 0 array on my current setup, or 
would I have to reformat? Would I have to configure Windows and Linux 
each seperatley to use the RAID array, or is that independent of the OS? 
I don't have a RAID card yet, but getting one is no problem.

Thanks,
Andrew
