High 'Raw Read Error Rate', but SMART says 'OK'
Hi, a customer's ReadyNAS 3100 shows the SMART values as you can see below. What bothers me are the high (?) "Raw Read Error Rate" values. The SMART Status is OK. Are those normal values or sh...
Update:
Since the time I wrote my post the values for Raw Read Error Rate only increased while the NAS did a "RAID scrubbing" on saturday night.
Before that and since then there is no change to the value on all four discs.

Hi,
I suggest to test disk with WD tool,
Shutdown the nas.
Extract only one disk at time and connect via a docking station to a windows pc and lauch WD tool (search it on WD support site for the latest version)
The values are not good, specially 'Current Pending Sector 1'
I suggest a full backup as soon as possible
