shares missing after drive failure

... Another thing I asked several times was, what do you do if you want to use something like Seagate's seatools? Do you remove the drive while the NAS is on? Do you format the drive before you put it back into the NAS? Whilst the NAS is on? My take is: Remove suspect drive whilst NAS is on Check drive Format drive (netgear supported didn't explicitly say, but kind of hinted that it would be a good idea) Put drive back into NAS whilst NAS is on ...

If the disk is ok, your process is needlessly stressing the array - if there is different drive that is failing you will lose your data.
That is because your method will wipe the suspect drive when you reinsert it, forcing a loss of redundancy until the array resyncs. (even if you skip the format step).

Seatools won't change the contents of the disk. So start with:

• Remove suspect drive whilst NAS is OFF


• Check drive (leaving the NAS OFF)


• Put drive back into NAS


• Power the NAS back on
