[TynesideLUG] Failing Hard Drive

Hi Alan,
Apparently the main things to look at are:
SMART 5 - Reallocated_Sector_Count.
SMART 187 - Reported_Uncorrectable_Errors.
SMART 188 - Command_Timeout.
SMART 197 - Current_Pending_Sector_Count.
SMART 198 - Offline_Uncorrectable
I've noticed some drives don't have 187/188. Power on time (9) is also
important. This is saying 908h+05m which is very low for an HDD. There
are 8760 or so hour in a year so this is only 5 weeks or so of power up
time. I've also found that drives that spin down to save power still
count this in the power on hours.
Here is an article I found:
https://www.computerworld.com/article/2846009/the-5-smart-stats-that-actually-predict-hard-drive-failure.html
Hard drive failure usually means clicking noises (Micro stepping to try
and recover data from corrupted sectors) or just an error saying the
disk isn't accessible. Have you checked the power/data connectors are
seated fully? Leaving a machine power on for a few hours can also help
drive moisture out of dusty machines too.
Regards, Derek
