How to replace HDD in RAID 1?

After a year, one of my Two 80 Gig Hard Drives failed in RAID 1 (mirror)
configuration. I get a warning on Boot-up that says "Incomplete RAID
configuration", I just assume it's a bad HDD.

Anyway, 3 questions:

1. How do I know WHICH of the 2 HDD's are bad?
2. Can I Hot Swap it? Or how to change it?
3. How does it "re-generate" data from the good HDD?

Thanks

Well, It won't "regenerate" data. In a mirrored Raid array the data is
being "mirrored" as it is being moved. As far as telling which HDD is bad,
I am not sure if you can do this in a riad array or not, but in an IDE
hookup you would just download the manufacturers utilities and run
diagnostics on both drives.

Read the manual for you specific raid controller. If your
controller is integral to a motherboard then read the manual for
an add-on PCI card using same raid controller chip.

In general you can install the (windows?) raid manager utility
which will show you what's going on, and after replacing bad
drive, rebuild the mirror.

Why care about hot swapping at this point? Turning system off is
always a safe bet, and should take less time than reading about
doing it any other way. Some IDE raid can be hot swapped but
generally it's if a single master drive per channel. Again, read
raid controller manual... you didn't even mention if these were
PATA, SATA, or SCSI.
