Resetting RAID 1, do I risk it??

This:

http://www.intel.com/support/chipsets/imsm/sb/CS-022836.htm

says that resetting a raid 1 array should result in both drives working as single disks, with no loss of data.

So, do I take a gamble on resetting my 2 disk raid 1 array? Such a disaster if the data gets lost..

(Moral support needed)

If in doubt, make a backup of all the data fist, Norton Ghost or Acronis will do the job in no time

I knew that would be the first answer, but alas I don't have anything big enough to back up to.

Take out one of the disks, do it to one of the disks, if it fails you can just format it, plug in your old disk (to the old array, in effect) and copy the data across, then do the same with that drive

Sounds good, will do next week when I have a chance.

So how do these controllers know which drive is the one to rebuild from? Say I do take one drive and format it, then stick it back in, how would it know to copy from the full onto the blank one..?

This isn't a sophisticated controller - when it needs to verify the array it just pops up in windows in the matrix software.

When you plug the blank one in, it doesn't start to auto copy stuff. You have to go in to the RAID software (for example the Intel Matrix Storage console on an Intel controller) and tell it to rebuild the array with that "new" blank drive.

So it would search both drives, find boot stuff on the intact drive and go from there. Hmm.

Either way, will have a go next week
