So this is an interesting one. Hitachi HDS721010DLE630 drive has SMART errors which caused the system to shut down. Drive seems to be reading sectors fine, but in universal utility it shows this:

That's quite a negative number of re-allocated sectors, it's almost the entire capacity of the drive. I'm guessing it passed the threshold a while back and then corrupted the SMART data. Just funny to see.
