Hi,
I'm hoping the Mac Pro forum is good place to ask these questions. I've set up a 2-drive mirrored RAID in my external FirmTek 4-drive esata enclosure. The RAID was set up with Disk Utility and consists of 2 x 1TB drives.
What I would like to know is how to swap out one of the drives and put in a replacement drive, a step-by-step process (i.e. "eject the raid from the desktop, turn off the power to the external enclosure, swap out drives, turn on power, use disk utility, etc., etc.). I'm not sure if the drives are hotswappable, if I do it all while disk utility is running, or what. My goal is to do this once a month so I always have one spare data copy in case something terrible happened to both drives in the external RAID.
Another question: Will the single drive removed from the pair function just like a stand alone drive if I attach it to another computer? I assume so.
Also, while I've heard that I should be running a separate back-up system as well (I use Time Machine to a 2tb drive), I'm curious whether rebuilding a mirrored raid is more or less time intensive than just doing a drag copy of all the content to another drive. I really don't care which method I use, swapping out a mirror raid spare or just copying to another drive, just would like to know which requires less time and babysitting.
And finally, forgive my ignorance, but if I end up getting a spare swapping system going with the mirrored raid, I assume that the spare with previous data on it gets totally wiped when I put it back in again, that the rebuilding process is "not smart," meaning that even if very little of the data has changed since the last swap out, the whole drive has to be wiped and rewritten from scratch?
Thanks for your help.
Paul
