SmartCtl Examples: A failed SATA2 Seagate 500GB Disk
A good example of a failing Seagate SATA2 OEM 500GB disk,
which was only up about 2 years. No big stress on it, just treat it as external ISO image backup disk.
SMARTctrl messages that proved the SATA disk is failed or likely failling:
(1) Bad blocks reallocat fulled!
e.g.
5 Reallocated_Sector_Ct 0x0033 012 012 036 Pre-fail Always FAILING_NOW 1815
(2) UNC Error found => UNC errors denotes "UNCorrectable Errors"
e.g. 40 51 00 ba 22 61 00 Error: UNC at LBA = 0x006122ba = 6365882
(3) Short and Long S.M.A.R.T Self-Test all completed w/ "Unknown failure"
e.g.
SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed: unknown failure 90% 14686 0
# 2 Short offline Completed: unknown failure 90% 14686 0

SMART Error Log Version: 1
ATA Error Count: 14971 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]
DC = Device Command Register [HEX]
ER = Error register [HEX]
ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 14971 occurred at disk power-on lifetime: 14686 hours ( 611 days + 22 hours )
When the command that caused the error occurred, the device was active or idle.
