Device /dev/sda SMART Failure

[linedan]

Hello!
I have the same log messages over and over again.
For example today, two times since now:
"
Nov 9 08:18:21 npis01 smartd[3097]: Device: /dev/sda [SAT], SMART Prefailure Attribute: 7 Seek_Error_Rate changed from 200 to 100
Nov 9 08:18:21 npis01 smartd[3097]: Device: /dev/sdb [SAT], SMART Prefailure Attribute: 7 Seek_Error_Rate changed from 200 to 100
"
Can anyone tell me what could cause this errors?
I already read that the failure-state should go back to 0 if everything is fine again, but i could not find any messange with this error going from 100 to 0 back again.

Thank you!

Hi,

this might indicate a problem with your drive. Have you checked the other stats [1]? It's a bit of an old post now, but the people at Backblaze have a post what they monitor to indicate a drive failure [2].

[1]

smartctl -a /dev/sda
