My optibay's HDD has suddenly become unreadable/mountable. Nothing physical happened, I was using it one moment, switched to bootcamp for a few minutes to use internet banking then back to OSX only to see message about the HDD being unreadable. In Disk Utility, I'm unable to mount it. Verify Disk says there's an error and asks me to click Repair, which also says there's an error and asks me to reformat. It's a new drive, 1tb WD Blue. Any way to recover my data? No backups, been waiting on some extra cash to get a back up drive.
