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 drive and is seen as added to NAS. I cannot find option to format and add again as JBOD.In system always an active disk/volume is selected (Blue with options) even if I try to select added drive (showing as black) and clicking on format it warns of disk protectors! I have all software kept up-to-date - RAIDar 6.2, Firmware 6.7.4 Can anyone please advise simple way to add a disk as JBOD. This NAS had 4 disks all of which are compatable and were working well, I have just tried to resolve a reported issue and am now down a drive and cannot start full rebuild. :-( Thanks........

I'm having trouble following your description. But the first question is whether XRAID is enabled. In the Volumes page, is the bar in the XRAID button on the right green?
If it is, you can't create a second volume.
What, exactly is the warning saying? If the drive has data on it, the OS will warn you just in case you have unintentionally inserted it (many NAS neophtes were mortified when the NAS reformatted their drive with all theiir data on it before Netgear added this feature). But if you really do want to format it, it normally lets you do so.
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....

It's not the diag, as that completed.

The disk itself is reporting this statistic, and it is not good.

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.
