The Synology has no facility to add a HDD manually, it just automatically detects disks which have no problems and offers them to add to an array. As this one has issues it won't see it. That being the case I decided to remove all the partitions in Linux and /then/ try it back in the NAS. To all intents and purposes it is now a flat HDD. The NAS still will not detect it.I have now formatted the drive in Gparted, ext4 for the whole partition, which suggests there is nothing fundamentally wrong with the drive. However, the NAS still will not see it.. I'm beginning to suspect the NAS itself of being the culprit.However, when I had the first faulty drive I remember swapping them and the NAS reported the other bay was faulty, so it does seem to be working.Check the manual for your NAS - what does it actually expect/require of new disks to be recognised according to Synology's documentation? It may be that it specifically requires a *blank* disk with no partition structure at all or a GPT rather than MBR disk for example. Perhaps if it detects a valid ext4 partition it refuses to touch it? Obviously I'm not sure. You probably already know this off the top of your head after shoving so many disks into it recently though. How did the other disks look when they were accepted? Without badmouthing your Synology too much, it does sound like an absolute piece of crap to be honest :[ Did you check the SMART status of the questionable disk under Linux while you had the chance? It could just be another bad disk in defence of the NAS. Cheers
Hi Mr Meowski,I have good, if odd, news. I turned on the NAS today and it recognised the second HDD, initialised it and is now busy rebuilding the array. That's without me even touching it since yesterday when it refused. All I can put it down to is that the connector in the NAS /may/ be going south. However, for now it seems to be working.
