[Pc_Support] Smart Self-test errors, fatal?

[Jason Boxman]

If an ATA drive is coughing up SMART errors, is it completely fatal?

I ran a couple of short self tests and a long.  The last short and long came 
back clean.  I `dd`d from the drive for a bit and it didn't blow up further.  
The drive experienced some shock a few weeks ago when I sort of, dropped, the 
case.  The other five drives seem fine, so far.  It's still under warranty, 
technically, although I wonder whether the g-force encountered doesn't void 
it.

SMART:

Error 2 occurred at disk power-on lifetime: 83 hours (3 days + 11 hours)
  When the command that caused the error occurred, the device was active or 
idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  40 51 00 b2 10 a4 e0  Error: UNC at LBA = 0x00a410b2 = 10752178

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
