how to wipe clean a previously used SSD? The drive in question was used in a synology 218+ NAS and I have managed to erase and un-initialise one drive, so apparently there is nothing on it now! The second drive has had 'the packages' erased but I cannot un-initialise this SSD! I have tried to view them with a USB dock plugged into a laptop (with windows pro 10/64) but the drives remain UNRECOGNISED! Despite the fact that synology DSM says they are 'clean'? I beg to differ because a brand new SSD would be recognised by windows 10 before it is partition/formatted! So there must be something still on there like formatting that is preventing it from being viewed? Any links/apps./useful suggestions please?
