You can also zero them in a Windows PC (using lifeguard's erase function), or delete the partitions (with Windows Disk Manager). Both methods unformat the disks, so the NAS will see them as blank. That shouldn't be necessary, but does no harm.

Hi StephenB
Would a quick erase (erasing only the first and last million blocks) be sufficient or does it need to be a full erase? Wondering as it would safe me 24 hours. You might know. ;-)

The quick erase is enough to remove the partitioning, and it does save a lot of time.
The full erase can sometimes uncover issues that the long generic test misses. So that can be useful if you aren't sure about the disk condition.

Hi,
After many days it is finaly done. :-)
However, with the last disc I am getting a failed expansion message. I have restarted the NAS, but not change. Not sure what to do. See attached log.
My total available space is 9TB for the 4 x 4 discs.
Have a nice weekend
