Readynas 104 - Cannot access data - remove inactive volumes to use the disk
Hi, I'm in trouble. My ReadyNAS had a problem with the power plug not connecting fully after moving house. Have fixed it and it is working, but Windows 10 won't read the data. Logged into the NA...

Each drive shows between 40 and 180 ATA errors - but Ive had this for 10 years.
smart_history.log shows these counts beginning on 21 Dec 2024, though nothing new since 8 Feb 2025.. Worth keeping a close eye on.

Device date says 7 April even though it is 23 April.
If you click on the settings wheel next to the time in the NAS admin page, is "synchronize time with an internet server" checked?

I am seeing this from last December

I'm not seeing errors on those disks now, but the NAS is choosing not to add them to your RAID array.

The "non-fresh" status means that some writes were missed on these two disks. That could be a result of the issue on 21 December, or it could have happened if the NAS wasn't properly shut down when you were troubleshooing the power problem.
Either way, it is possible to force the array to mount from tech support mode. If you want to pursue that path, let me know and I can give you advice over private message (using the envelope icon in the upper right of the forum page). There could be some damage to some files, since some writes were lost. But it is likely slight.
The other path would is RAID recovery. You'd have to buy some equipment and software to do that yourself, or you'd need to find a recovery service. You could mail them the disks to avoid the travel complexity. This is lower risk, but would cost. (And I do think the risk is slight if you are careful to follow my instructions).

My entire 60 years of life is on this - my kids pics, tax returns....As Sandshark says, you need a backup plan. Any device can fail at any time. After your data access is restored, we can provide some advice there. Options include a USB disk (either attached to the NAS or a PC), Cloud Storage, or some combination of both.
US pricing for 2 TB of cloud storage is about $10 USD per month, and that is likely enough to hold your most important files.
I recommend that you remove the log zip from your cloud storage, as there is some privacy leakage when you post the logs publicly.
I have downloaded the log zip, and will post back in a bit.
Since you came here before you tried anything on your own, potentially making things worse, there is a good chance you can recover most or all of your data with StephenB's help or the use of recovery software. But you are probably going to need some place to which to copy the data. You also need to have a backup plan for your irreplaceable data so you don't have to go through this again, so that device can also serve for the basis for doing that.
As you have found out the hard way, RAID and hardware can fail in ways that make all the data inaccessible, though it's better than just individual drives. True backup (on another device) is the only way to make sure your data is protected. There is an old IT saying that still applies: "If you have only one copy of something, you must not think it's very important." For the best protection, that backup is off-site so fire, theft, etc. can't cause the loss of both.
So while StephenB looks for a way to recover your data, you need to start thinking about what that backup method is going to be. Cloud storage, USB drive(s), and another NAS are all options and what you choose can depend on how much data is involved, amount of risk you are comfortable retaining, and budget. StephenB and I both use other NAS as our primary backup. I believe he also uses cloud backup for the most important stuff, as that is both off-site and further backed up by the cloud operator. I have a NAS located at my brother's house in another state, but have also recently started putting some things in the cloud.
If you decide on another NAS, then you also need to decide if you want to buy a used ReadyNAS since you are already familiar with it, or one from another company who's still supporting theirs. If you choose another brand, you'd most likely want to make it your main NAS and relegate the ReadyNAS to backup duty.
