You can download the log zip file.  Disk-info.log might give you some info, though generally "dead" disks aren't listed there.  You can also look for i/o errors in system.log and kernel.log.

 

Disk-info.log: only active disk

The safest way to test if this is the chassis is by inserting a scratch disk into that bay (by itself) and try a factory install.  That eliminates the chance of data loss.
