If what you want to do is mirror an existing hard drive or
partition, then yes, it's possible. J
You'd think that since it's a mirror, it would work fine right?
Apparently not. Last time I tried this stunt, I nearly toasted 45 GB of

Can I run mkraid when hda3 is in use? I would use the following

The general consensus seems to be that the cheap ATA RAID cards (around $100
USD) are not worthwhile. They don't implement RAID in hardware, they rely on
drivers to do the actual work. The more expensive ATA RAID cards (around $300
USD) do implement RAID in hardware and work well.

I get the feeling that the only IDE RAID controller you have heard of is

I want to setup a RAID-1 system using IDE RAID. I've searched around google,
and looked at what the kernel offers. I have a a few cards in mind that I

about which ATA raid card was the better than the rest.
