SCSI hard drive failure ?

I recently bought and installed a secondhand scsi
drive but after only a couple of successful writes,
the disk went 'click'... and I lost I/O to it.

I have searched thoroughly for information...
but I can't find out how to really tell if the disk is
DEAD... or if it can be recovered...
Disk is 'seen'by firmware at console and kernel by
diskconfig but remains unreachable to configure.

Some background
scu> set nexus bus 1 target 0 lun 0
Device: BA03611C9B, Bus: 1, Target: 0, Lun: 0, Type:
Direct Access
scu> test
Performing Self-Test Diagnostics...
scu: 'send diagnostic' failed on device 'BA03611C9B'
at nexus [1/0/0]
scu: Sense Key = 0x3 = MEDIUM ERROR - Nonrecoverable
medium error,
     Sense Code/Qualifier = (0x31, 0) = Medium format
corrupted
The Self-Test Diagnostic FAILED!!!

# disklabel dsk5
disklabel: dsk5: I/O error

# hwmgr -get attrib -id 65
tells me some weird (?) things such as block_size = 0
and capacity = 0

Any advice appreciated,
Bill Hall
