SMART overall-health self-assessment test result: PASSED

But the report does contain records of errors, eg.:

Error 5 occurred at disk power-on lifetime: 18734 hours (780 days + 14 
   When the command that caused the error occurred, the device was 
active or idle.

   After command completion occurred, registers were:
   -- -- -- -- -- -- --
   40 51 03 0d 13 ac e0  Error: UNC 3 sectors at LBA = 0x00ac130d = 11277069

It's a 36G disk.

Thanks. I'll probably replace the disk.
