Guys, I have finally managed to find the bad disk it is making a weezing noise and it shows as 4GB in total instead of 1TB.

 

Your NV+ v1 NAS uses a dedicated parity disk, and I believe that is the disk that failed. Those parity blocks are written to an unpartitioned area of the disk.

Was this disk in slot 4? Usually the parity disk is in that slot.

Now if I put the labelled disks back into netgear will no data loss occur if I replace the failed drive with a new one, will the volume rebuild with minimal data loss?

 

Assuming you've correctly identified the failing disk, It should boot up without that disk in place. 

In general RAID tends to be all-or-nothing.  When you add a disk, the system should resync with no data loss.  If that process fails (due to a second failed disk) then you will lose everything.

Shutting the system down before it goes to check the volume would be ok?

 

There is a boot option to skip the volume check, and you should use it in this case. Then make a backup before doing anything else.
