I have a headless machine that stopped booting, so I pulled it out for diagnostics and got a message that one of the harddrives was about to fail, so I pulled them all out and I need to get everything off, before figuring out which I need to get rid of. I wasn't sure which drive was failing, because it only said "Harddrive 1" and I don't know which it referred to.
I'm wondering the best way to get everything off. I'm worried if I copy everything, I could get corrupt data and not realize some files are wrong until the drive is completely out of commission. What are my best options to get everything off in a way I can safely move to new storage?
