HDD Failing? ("Reallocated sector count has increased...")

Your comment in an earlier post about the "data being mirrored and therefore you hadn't lost anything" suggests that you don't have a backup of the data on the nas. This is not a good idea, I'd suggest creating a backup strategy.

You are quite right I need a proper backup strategy. However, the redundancy of the RAID config, covers me for a single HDD failure, and my important stuff (mainly photos, plus the odd few docs and worksheets, are backed up to the cloud). If I lost both drives, the worst that would happen is I would lose all the DVDs/blu-rays I've ripped over the years, whilst it'd be an nightmare to re-do these, I do have the original discs stored elsewhere, so not gone forever!

To re-iterate though, I do need to set up a proper backup strategy for my photos at least, currently it's done "as and when" I remember!
