[Smartmontools-support]Raw_Read_Error_Rate goes up and down?

[Sebastian W. <se...@gm...>]

Hello,

first I must say that I tought the Prefailure Attributes can only become
worse and not better?

Here my are the smartd messages:

Jul 14 15:26:31 [smartd] Device: /dev/hdb, SMART Prefailure Attribute: 1
Raw_Read_Error_Rate changed from 73 to 72_
Jul 14 15:56:52 [smartd] Device: /dev/hdb, SMART Prefailure Attribute: 1
Raw_Read_Error_Rate changed from 72 to 73_
Jul 14 16:27:13 [smartd] Device: /dev/hdb, SMART Prefailure Attribute: 1
Raw_Read_Error_Rate changed from 73 to 74_

The values are changing mostly between 72-74, somethimes up to 76.

Is this behavior normal on this kind of disk? It's a Seagate
ST340810A (I append the smartctl output). Or it is a sign
that the disk is about to die (not tomorrow, but slowly)?

Thanks,
Sebastian
