Need to securely wipe data on a single RAIDed drive?
I have 2x 2TB drives running RAID-1 and plan on upgrading to 3TB drives... do I need to take any special steps to nuke the data if I am selling them separately or should a standard format be safe since im assuming striped drives are impossible to read on their own anyways?
Honestly, even a RAID 0 (or 5 or otherwise striped RAID) I would still write 0s to it before selling. The size of a stripe could very well be large enough that interesting chunks of data could be pulled. I think it's doubtful that anyone would bother, but it's easy enough to wipe the drive well that you might as well.
