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 e...

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.
I'm fortunate enough to occassionally and sporatically log back in. The status on the LCD Display is normal and no errors. When I log into the UI, it shows the status of the NAS as green and disks are all green. I can't use windows explorer to browse the share anymore. I checked the logs and over the past couple days its just Disk 3 having errors currently.
I'm sure I can enable SSH and putty in. I've never SSH'd into it before, what should I be looking for?
Current Summary: I have a 4 x 3TB Raid 5, with disk 3 throwing lots of errors, UI sporatically allowing me in (very slow response when I get in), I have a replacement drive ready in hand, I'm unable to browse the network shares.
