resinch a dieing disk or add new disk & resinch?
Apologies again. I posted the same message in the "Test" board, and got complete unnoticed / unseen. As it is rather urgent, I am re-posting it here, where I hope it will be seen. I could not find a b...
Sorry, this morning I restarted some HD4 scanning before reading your mail, and it hasn't finished yet (69.6% done).
Sure, I can start NAS without HD1, but I don't know "how" I would know if my files are accessible: I have (say) 4Tb of data, which is everything from Movies, TV cooking programs, all my digital photos (and video clips) since ~2000, work stuff, backup data for various PCs, laptops, netbooks, phones etcetera.
I don't know if seeing a folder structure means that the data is accessible, or I may see a folder, but when I click on it, the folder will open, but I can't open the file. My experience of file damage, is that a file which has got corrupted "is there" (sometimes taking the exact amount of space) but does not open, although some types of files do open partially (like some pictures, or movies which don't run the full length).
How would I know if I had data loss? Apart from opening one zillion files, I would never know.
Also you said that NAS would do a "volume scan", and that "some data loss may occurr" - which is what I would wish to avoid.
So we got into HD testing, and, apart from Victoria which we speculate that could be generating "false positives", HD1 has been perfect, all test passed, SMART showing no evidence of ever a problem, etc.
Basically I thought that we would be satisfied with that, so I cold-refit HD1 and let it finish the synching which it started doing. I stress that the resinch did not stop or fail - I interrupted it as soon as I realised that the NAS, which was rebooted from the netbook in another room, was back online but on a "waiting (or so it appeared) state". I rushed to the NAS, I saw that it was re-synching, and I immediately switched it off (soft option).
On the other hand,
so obviously the initial "fail" flagged by NAS is very much on your mind
And you obviously mean that you would run Seatools destructive test on HD1 before refitting in bay4, I presume.

On the other hand,
If HD1 was partially synced, then I would certainly put HD4 into slot 1 and re-establish redundancy. HD1 is still perhaps questionable, and you don't want that resync to fail.
Then I'd put HD1 into slot 4.
