How to determine how dead a HDD is from SMARTCTL report

Solution 1:

I did some tests and I'm not sure how bad this is

Short Answer:

Backup this drive and replace immediately.

Long Answer:

A company called Backblaze has collected data on hard drive failures. It has released that data in company blogs, highlighting which manufacturer's drives failed more often than others.

In a recent blog it published data indicating exactly which 5 SMART attributes indicate imminent drive failure:

From experience, we have found the following 5 SMART metrics indicate impending disk drive failure:

• SMART 5 – Reallocated_Sector_Count.
• SMART 187 – Reported_Uncorrectable_Errors.
• SMART 188 – Command_Timeout.
• SMART 197 – Current_Pending_Sector_Count.
• SMART 198 – Offline_Uncorrectable.

We chose these 5 stats based on our experience and input from others in the industry because they are consistent across manufacturers and they are good predictors of failure.

The article goes on to suggest:

SMART 5: Reallocated_Sector_Count
1-4 keep an eye on it, more than 4 replace

SMART 187: Reported_Uncorrect
1 or more replace

SMART 188: Command_Timeout
1-13 keep an eye on it, more than 13 replace

SMART 197: Current_Pending_Sector_Count
1 or more replace

SMART 198: Offline_Uncorrectable
1 or more replace

In your case 5 (raw value 2), 197 (raw value 484) and 198 (raw value 371) are showing signs of failure.
