ReadyNas 104 Disk Errors
I have had a ReadyNas 104 for several years and it has worked really well. Last week I logged into it, and saw disk errors in the logs and have monitored it closesly over the past few days. My disk errors have started on Disk1 and now am seeing errors on Disk3. Disk errors on disk 3 have been ongoing for the past few days, while Disk 1 seems to have quieted down. I have 4 x 3TB drives in a RAID5, and am concerned with 2 drives throwing errors, that I may lose the Raid.
All 4 disks are still green and online. I'm on version 6.9.3
Drives have ATA errors and rewritten sectors
Here are my disk errors:
Disk: Detected high uncorrectable error count: [12264] on disk 3 (Internal) [ST3000DM001-1CH166, W1F5QEWW]. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
Disk: Detected increasing pending sector: count [12264] on disk 3 (Internal) [ST3000DM001-1CH166, W1F5QEWW] 679 times in the past 30 days. This condition often indicates an impending failure. Be prepared to replace this disk to maintain data redundancy.
Any advice? Do I let the drives fail on their own or do something manually?

I'd back up the data first, and then replace disk 3. If that works without data loss, then replace disk 1.
I recommend NAS-purposed drives for the RN104 (not desktop drives). So if you prefer Seagate, replace them with 3 TB IronWolf drives (ST3000VN007). The Western Digital equivalent is the WD30EFRX.
Since you have a pair of disks to replace, you could also take the opportunity to increase your storage by getting larger drives. For instance if you purchased a pair of 8 TB NAS-purposed drives, your storage would increase from 9 TB (~8.2 TiB) to 14 (~12.7 TiB).
Thanks for the quick reply!
I have most of the important data backed up, but not all of it. I'm attempting to browse my share to back up everything and it times out. I try to log into the UI and it will sit on the Netgear ReadyNAS page for over 10 minutes, and now is sitting at the Connecting to the ReadNas Admin Page... page with the blue bar that is sliding accross looking like it is trying to load. Then once the bar is complete it says the ReadyNas Admin Page is offline
Last night I hit the power button twice and let it gracefully power down and powered it up this morning.
How do you recommend replacing drives in this condition? I'm unable to log into the UI at the moment. If I physically pull out the online drive, I don't think I'll have the ability to log in to manage the replacement drive and bring it into the RAID and start the raid rebuild process.
What is the status on the display and in RAIDar? Do you have SSH enabled so you can check status with that?
It sounds likely that drive 3 is making it hard to impossible for the NAS to properly boot. You could remove drive 3 and try booting in read-only mode to find out, but doing a bit more sleuthing before hand is a better approach. Definitely do not remove drive 3 and just boot normally. If you guess wrong, your volume likely gets destroyed.
