Monday morning i verified that SDC hard disk didn't have bad blocks
and i tried to re-add to the Raid md1. The raid array was rebuilded
with no problems.
I didn't modified the TLER settings on this four hard disk (Default
Value 7 seconds).
I have installed this type of drives beacuse with the WD Velociraptor
i had the same issue :(
Can be an issue of the Server Hardware?
