So a few years ago I set up a computer with a RAID 1 set-up. Everything has been going fine, until a month ago the computer wouldn't start saying that there was a disk failure. I didn't need to use the computer at the time so I ignored it.
Today I decided to look at it again. This time it still says that my RAID is in "critical" however it does start-up. I assumed that one of my drives just died on me. However, when I unplugged the power from the drives to check which once wasn't working, both drives continued working! Which I don't understand whatsoever. I went ahead and purchased a new drive a few weeks ago to replace the one I presumed was dead.
Can anyone think of any way to further find out what the problem drive is?
I've attached a picture of the error that momentary pops up on my screen at bootup.
