Hey

 

 

 

 

Should I be worried about drive 3?

(both regular and extended SMART tests as well as IW health test all come up OK)

 

I don't know what kind of information may be relevant here so I'll just list the following, but do not hesitate to tell me if more detailed information could be useful.

 

CPU:  i7-4790k (4cores/8threads)

RAM: 4GB (2x2GB) DDR3 1333

MB: Asus Z97-A

sATA ports: 6/6 sATA3 ports from MB (drives 1-6); 3/5 sATA3 ports from PCIe3.0 x4 AIC (ref) (drives 7-9). All 11 ports detected properly when loader was built (satamap).

Power failure of drive 1 during data scrubbing

 

 

File system check -> OK

 

 

data scrubbing restarted with write cache disabled for disks 1-4

drive 3 still stuck @ 100% utilization...

It looks better this time around. Except for disk 3 which is still stuck at 100%
