The system I do have to test with has a "pop", but that's from the speakers not the drive.
However, the S.M.A.R.T. data was also shown earlier to provide a record of the unnecessary wear and tear.
Here it is from two hibernates (Linux "suspend-to-disk") before patching:
- 4 Start_Stop_Count 0x0032 099 099 020 Old_age Always - 1711 + 4 Start_Stop_Count 0x0032 099 099 020 Old_age Always - 1712 .. - 12 Power_Cycle_Count 0x0032 099 099 020 Old_age Always - 1051 + 12 Power_Cycle_Count 0x0032 099 099 020 Old_age Always - 1053 .. -192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 126 -193 Load_Cycle_Count 0x0032 015 015 000 Old_age Always - 170404 +192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 128 +193 Load_Cycle_Count 0x0032 015 015 000 Old_age Always - 170405
With the patch applied, I don't see *any* new activity in those S.M.A.R.T. attributes over multiple hibernates (Linux "suspend-to-disk").
Next up, I'll try a few shutdowns and see.
But we should still get Stephen Clark or one of the other reporters to confirm it on their systems.
