RN104 format/adding volumes/initialize
I have had report of issue with volume/disk #2, found no way to format in NAS so removed drive and remove partions/run diag with no fault found (suspect bad file or like to be cause). Have re-added d...
Many thanks for reply. Xraid is not enabled and I have now added disk back as a volume and it has auto formated. Diag still report issue with this disk although I formated NTFS and run WD diag witout issue showing! Suspect the diag with this NAS OS is at fault, I have add a sample of report below for you to see. After adding I did several restarts of NAS once the installation had completed. Of the 4 drives 2GB are 2 WD Red and the other 2 are Seagate ST, the issue is with one of the Seagates which at present has only an empty share/folder. Thanks....

This is a disk write error, which also is not good. I can't tell from this snipped if it was on disk 2 or some other disk.
Can you post the SMART stats for disk 2?
You can also remove it, and retest it with Lifeguard. Go with the destructive "write zeros" test. I am thinking that turn up problems that the non-destructive test missed.
Many thanks for reply. I have decided to replace the 2 Seagates with WD Red 2GB drives at month end so am searching for best price at present. This will have all drives matching and will be SAN specific drives. Again many thanks for reply and have found this forum very helpful. Jimmy F....
