Elephant, elephant, elephant.
My NAS (Seagate four x 4TB) has lost the data volume.
All four 4TB drives SMART test OK, but the volume is reported as failed, so all shares are gone, and the available space shows 100%.
Turning it off and back on again hasn't helped.

That's is my entire archive backup system, plus my personal media. I've got the current stuff, and the backups of that, but not the archives ... and not the personal stuff which I'd like back because that's the only place it's stored (Video gets BIG).
And while I really like backups, I don't have a backup of my backup ...

Given recent events (to you and to den2k88), it looks like my extreme paranoia is paying off. I keep a full backup of my NAS off-site, updated monthly.

The Tao Of Backup: 2. Frequency[^]
(There is something to be said for incremental backup as well. It allows more frequent backups without the backup volume going completely out of hand.)

If I were running a business, I would definitely follow the Tao.
My situation is similar to OG's. I have lots of archival stuff, some active files, and a few personal programming projects. The archival stuff (which would be difficult or impossible to reconstruct) is backed up monthly off-site, as part of the NAS backup. The active stuff is backed up daily to the NAS and monthly offsite. Current personal programming stuff is in off-site repositories.
I obviously use an incremental backup scheme for the daily backups.
If my house catches fire or I suffer a burglary which cleans out everything, I figure that I've got bigger problems than reconstructing the last few weeks of my daughter's homework and such.
The novice became suspicious and said: "Master, is all this 'Tao of Backup' stuff just so you can sell more copies of Veracity?"
The master said: "Now you are truly enlightened."

Oh man, that sucks. Hopefully there will be a post that you've recovered the volume!

So you didn't have a backup of it. What a pity. A single copy is not a backup, even when stored on a backup device.
Such is life. And it is getting sucher and sucher every day.

download Testdisk
It's a windows console app written by a smarty pants that can get data off "raw" drives or drives that were ntfs and now are raw. It's tricky to use but has save customer's data on more than one occasion.
Also, partition manager has a community edition and can undelete volumes / partitions.
Alternatively run chkdsk against it and see if window reports it as raw instead of ntfs.
If it's an SSD then sorry, that's how they'll do ya.

It's a RAID 5 NAS running some variety of Linux, I think.
Which means I know enough to leave well alone until I've heard from the manufacturers tech support - I'd probably do more damage trying to fix it than I'd cure ...

Sounds like the controller died.

RAID is awesome in theory, but when it's the controller itself that dies, you're truly FUBARed. Unless the controller itself has some redundancy, but you won't get that with consumer hardware...
So I always get the largest drives I can get and get them in multiples. Spanning multiple smaller disks, IMO, is just asking for trouble in the long run.

Agreed.

There is a very nice table summing up the various RAID types - Standard RAID levels.

I'm ~99% sure any consumer NAS is going to be running some flavor of linux softraid not a hardware implementation.

When my relative got scammed and lost his data (see here[^]) I managed to get over 95% back (even many things deleted previous to the scam).
I used "FileScavenger" in bootable mode.
In the thread there are some other tools mentioned. Just in case you want a couple alternatives more

Maybe their container is bad. Can you pull drives and mount them in another container?

Replying also to @Daniel-Pfeffer
I use RAID 1 (mirroring) for a reason. The chance that both drives die at the same moment is low enough that it offsets the cost of backupping 4 TB (theoretical) of data. The only consumer option that can do such a thing is a blueray burners, which with its cost, cost of volumes and time required is really not an option.
Data Tapes are truly not affordable for home, slow as all hell and they tend to fail a lot during restores. I could have gone with a 4 bays NAS but the cost was really astronomical wrt a 2 bays one.
Cloud is not an option because 1) I have 5 Mbps in upload, and I'm very lucky since in my country anything above 512k in upload is a privilege and 2) True cloud plans are not cheap, not safe and you never know when they will pull the plug. Plus I don't want my documents and contracts to be shared onto some ****ese or ******an server, knowing their past espionage exploits.
So balancing cost and effectiveness, I chose a mirroring solution.

Mine is a four bay, with RAID5 so I can survive a dead disk (and have done, on a previous, smaller NAS) without any data loss, and backup becomes an even bigger problem since that's 16TB of disks holding up to 12TB of data - even an incremental backup would take forever and require expensive equipment. Tapes and cloud I don't trust either!
It's been a damn good solution up to now, but ...

I understand the cost issue for RAID 5 vs RAID 1 - more drives, more expensive NAS, etc.
If your storage needs are larger (e.g. more than 12 TB), RAID 5 can actually be more cost-effective than RAID 1. To get 12 TB of RAID 1 storage, you need 24 TB of physical storage in 2x12 TB disks. To get 12 TB of RAID 5 storage, you only need 16 TB of physical storage in 4x4 TB disks. There is still a cost premium on large disks, so the cost savings on the smaller disks and on 8TB of storage should more than pay for the increased cost of a 4-bay NAS.
I also distrust data tapes, the "cloud", etc. What I have done is to buy 2 sets of 4 TB portable drives to which I copy the backup. These are stored off-site, and rotated monthly. This means that at most I will lose a month of my personal stuff, which I figure is recoverable.
(If I ran a business from home, I'd have a more robust backup scheme.)

Yeah! When I used my regular starter word and started getting GREENs... initial reaction was  ... which soon turned into  !

That's why the "easy" way to play is to use 2 or 3 starter words with no letters in common and check for over half the alphabet before you try to guess the word!
