It maybe too late, but I once had a disc in my MD600 fail, and the unit showed both failure lights. I probably did something to get it in that state, but I managed to rebuild the data from one of the discs, despite both lights having showed.

You might try each drive separately. YMMV.

Speaking from experience, two discs can fail very close in time to each other, if they've come from the same batch. This is especially true if they don't get much cooling.

It's one reason it's a good idea to buy drives from completely different batches, if possible.

Thanks for all the suggestions.

I hope to have an update on the status this weekend.

I had a similar experience to Ludwig, both lights showing and the unit sat doing nothing but flashing lights, the pattern didn't fit the user manual description. Ultimately it was a single drive that completely failed. Helpfully the unit will run with just a single drive. I replaced both drives at the same time. I rebuilt one drive from my (thankfully recent) back-up as it wouldn't rebuild from the original, non failed disk. The second new drive did rebuild from the good new drive when installed so maybe the old "good" drive also had some problems. Thanks to Ratbert for the help and advice at the time.

As has been pointed out the lack of any useful drive health type utilities on the MD600 is a problem. I do appreciate it's simplicity most of the time. I seem to spend more time tinkering and checking the status of my microserver and NAS back-up drives than I do actually using them......

Had a similar problem on more than one occasion, however Ratbert talked me through successful resolutions when problems arose.

My MD600 showed failed drives but not simultaneously, after hard reboot the opposite (L or R) reported failed condition.

Seagate tools easily identified the failed disc and a new disc inserted rectified the problem.

Most disconcerting at the time, which just confirms the poor diagnostics of the MD600. I have no faith in what the LED display shows.

I thought that the health of those things were actively monitored by mothership to pre-empt any failure whistle

It seems everyone has a favourite Hard Drive, in speaking with an IT manager for a very large company who uses many multiples of these units, he suggests only using the ones certified for 'Enterprise' as the manufacturers are much more fearful of the backlash from companies using their products then from consumers if there is failure, apparently the drives are more rigorously tested and have longer life spans.

It appears there is a significant range in the capacity size of Hard Drives that everyone is using, is there any consensus on the capacity capability of MD600 or TwinStores?

MD600 and TwinStore can take pretty much any commercial hard drive (obviously SATA, not M.2).

It was the older Ensemble that was limited to 2TB.

Update:

Thanks to all for the helpful replies and PMs on this (especially Russ). I removed the hard drives individually and determined that only one had failed. Thanks for the heads up that the indicator lights are not reliable, and that the store will operate on only one disc- this was indeed a good suggestion.

The disk in bay two failed. When this bad disc was removed, I could once again access my library and Sooloos behaved normally (using only the disc in bay one). When I did the reverse experiment, my library was empty, as was the problem I observed when I returned from my trip. Not entirely sure why only one failed drive would result in an empty library and both lights on?

I replaced the bad drive with a new WD Red as suggested here, and after the installation and mirroring, both lights are off and system is operating normally. I just completed a fresh back-up using the Control:PC Wizard.

I tested the bad drive using Seatools and failed the first test! Clearly a bad drive. I bought two of the WD drives when I placed my order, and am thinking about proactively replacing the other drive soon.

Thanks again to everyone!
John

Indeed - great news.
A tip I once read re NAS drives: never buy more than one at a time. If there is a faulty batch, you could be buying into it. if you buy different brands or the same one but from different suppliers and/or at different times then you are lowering your risk of *both* being faulty. Of course, there may be a slightly higher risk that you'll get *one* faulty one, as you're hitting multiple batches, but that's easier to cope with.
