ReadyNAS 204 won't load admin page
I have a ReadyNAS 204 with firmware 6.10.7 and four 8TB drives. Have had it 4 years (bought it gently used) and it ran without any issues. I don't run any apps on it, I only use it to store media f...
If you power up with three drives you'll know immediately if you've solved the problem. Your volume will mount, though it will be listed as "degraded" due to lack of redundancy, and you should have access to the GUI. Then when you insert the new drive into the empty bay, you should see the NAS recognize it and begin to sync.
If you power up with the replacement already in place, it will start to re-sync immediately and if you can't get into the GUI, you won't know if it's because the sync is hogging too much CPU or something else is (still) wrong.
I honestly can't remember if SSH is enabled. I think so, but I set this up 4 years ago and haven't had to make any major changes and so I haven't been to that screen lately. I can't verify since I can't get into the admin page.
I've never used SSH, but I'm sure I can find instructions on using it somewhere and figure it out.
Based on what you say (which I suspected), I think my priority now should be replacing the drive. I've never done that either, but I believe the manual has instructions, and as it's a hot swap drive it should be a piece of cake.
Thank you for replying.

My guess is that it is not.
But you can test it easily. If you are using windows, enter ssh root@nas-ip-addess in the windows search bar (using the real NAS IP address of course). From a Mac you can open terminal and enter the same command.
If ssh is enabled, youi'll probably get a message asking to confirm a fingerprint (say yes), and then you'll get a password prompt.
If it's not enabled, you should get a connection refused message, or possibly the text box will just close.

A hot-swap is what I always recommend. The main thing is to make sure you pull the right drive. If you get that wrong, then you can lose data.
FWIW, I always test my replacement drives in a Windows PC first, using vendor tools. Seatools for Seagate, and Dashboard (or Lifeguard) for Western Digital. I run the full non-destructive test, and also a full erase/write zeros test. Some out-of-the-box drives have passed one of these tests, but failed the other.
I have ordered a new disc, it will be here on the 14th.
SSH is not enabled.
Meanwhile, the error messages I get say "Detected increasing pending sector: count [4224] on disk 2 (Internal) ". Now all I have to do is figure out is which one is disc 2.
The Hardware manual does not give me this information. Is disc 1 the one on the farthest left, or the one on the farthest right??? Normally I would assume Disc 1 is the one on the far left, but it is never wise to make assumptions with hard drives.
You'd think they'd provide this information in the Hardware manual, but they don't, and neither does RAIDar.
Do you know if I count from the left, or from the right?
I think I figured out which drive bay is Disc 2. The error message I get says this disc is failing:
disk 2 (Internal) [WDC WD80EFAX-68LHPN0, 7SGTHUPC]
And when I look in RAIDar, I find that not all the drives are identical (it came with 4 drives installed). The 1st and 2nd drives are identified as
Channel 1 WDC_WD80EFAX-68LHPN0 8TB, 46C/114F
Channel 2 WDC_WD80EFAX-68LHPN0 8TB, 51C 123F
Channel 3 WDC_WD80EMAX-00WJTA0 8TB, 50C/122F
Channel 4 ST8000DM004-2CX188, 8TB 45C/113F
So it has to be the second drive from the left, which I can double-check when I remove it from the bay.

If there is any doubt, than instead of the hot-swap you should power down the NAS before removing the drive, so you can check the serial number. Then boot up with the three remaining disks.
Do the clean shutdown procedure from the front panel:
If the status display screen is not lit, press the power button to wake it up.
Then
- Press the power button. Instructions for graceful shutdown should be on the status display screen.
- Press the Power button again. The system should now shut down gracefully.
I was actually intending to power it down, remove the first 2 disks and examine the serial number, then replace the bad one with the new one, put both disks back in the NAS, then power back up again.
But you suggested powering it up again with only 3 disks and then doing a hot swap. Is there a reason why that is a better idea than doing what I had planned? I'm just curious ... I don't know a lot about NAS technology and I want to learn more.
The new disk will arrive on Thursday.
I have a Western Digital 10TB external hard drive connected to the NAS through one of its USB ports, and I've been backing up the NAS to the external drive for about 2 years. I double-checked this connection yesterday and I could not connect to the external drive in Windows Explorer, and the synchronizing software I've been using for years also can't see the external drive.
So I moved the external drive to a USB port on my computer, where I can access it without problems, and I synchronized all the folders to make sure I have a current backup of the NAS.
I don't know why the NAS was refusing to connect to the external drive, but it definitely wasn't, and this is a new thing, because when I checked it a week ago, the connection was stable.
