Raw_Read_Error_Rate decreasing?

[loz678]

I've been keeping an eye on this drive and noticed today that the Raw_Read_Error_Rate has decreased since the 18th. Can anyone shed some light on this, surely it can only stay the same or increase?

 

Also , I'd appreciate any ideas on why this drive is returning so many hits for Raw_Read_Error_Rate, Seek_Error_Rate, G-Sense_Error_Rate and Hardware ECC recovered. I recently changed the sas->sata breakout cable but to no avail.

Raw_Read_Error_Rate, Seek_Error_Rate

On Seagate these attributes have multi bit values, to check the number of actual errors you need to use:

smartctl -a -v 1,raw48:54 /dev/sdX

Which BTW is still zero for the drive above, for seek error rate, you'd use:

smartctl -a -v 7,raw48:54 /dev/sdX

Also zero errors for now.

 

Hardware ECC recovered nothing to worry about, g-sense error rate the same, just look at the normalized value for that one.

 

For that disk the attributes to keep an eye are command timeout, currently shows 10 errors, not much but the go to monitor, and the CRC errors, though those could be old and are not a disk problem.
