Quite possible. I have two ST31000340AS drives with the bad SD15
firmware and it threw a bunch of DMA errors last night, and smart
shows:

Error 2 occurred at disk power-on lifetime: 366 hours (15 days + 6 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 42 53 d7 0d  Error: UNC at LBA = 0x0dd75342 = 232215362

  Commands leading to the command that caused the error were:
  CR FR SC SN CL CH DH DC   Powered_Up_Time  Command/Feature_Name
  -- -- -- -- -- -- -- --  ----------------  --------------------
  c8 00 00 ff 52 d7 4d 00   5d+06:34:09.759  READ DMA

Error 1 occurred at disk power-on lifetime: 231 hours (9 days + 15 hours)
  When the command that caused the error occurred, the device was
active or idle.

I've got 2 WD black drives on order to replace these two ST31000340AS,
and originally my intention was to use them for separate filesystems,
but I think I'll gmirror them now, to be safe(er).
