Comment 9 for bug 2053041

I tried on a random lab machine with 2x HP MM0500GBKAK disks.

With 6.5.0-18-generic:

Before:

SMART Attributes Data Structure revision number: 10
Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
...
  4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 293
...
 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 293
...
192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 292
...

and after:

SMART Attributes Data Structure revision number: 10
Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
...
  4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 294
...
 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 294
...
192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 293
...

Seems Power-Off_Retract_Count increments regardless.

I rolled back to 6.5.0-15-generic, and saw the same behaviour.

I think I need to try a different lab machine with different disks.

Thanks,
