RN104 New Volume
Could not see this particular problem, forgive me if I have missed it and started another thread for nothing. I have a new RN104, I started it for the first time with a new 4TB disk and followed the ...
- Jul 03, 2014With RAID-1 the two disks are mirrored, so adding the second drive does not add capacity - it adds redundancy. If you hot-insert a third 4 TB drive the space will increase to 7.2 TiB, and the NAS will switch to RAID-5. You still have redundancy which protects against a single drive failure.
If you wanted jbod (no RAID) then you should start over with another factory reset (with only one drive installed), switch to FLEXRAID/JBOD, and hot-insert the second drive.
Adding a new disk to the RN104 is easy, I am puzzled by your comment on "not simple to add more disks".

I took the disks out of NAS and fitted to this PC, then run WD and Seatool Diags, SMART test, Self test, Short test, Long test. Disk 3 failed the long test on both diags. Incidentally, he clearest read for SMART came actually from Acronis Disk Monitor.
Unless you are asking if I run the long tests more than once, in which case no, I didn't
Sorry, I am not sure what you mean.
Have you run a few passes of the memory test boot menu option?
