Windows cannot access \\mynasname\PC_Backups

[DeonH]

Hi all and thanks for your help.
Setup:
Windows 11 64-Bit with most recent updates installed.
NAS: Western Digital My Book Live Duo; RAID 1 (Support Discontinued.)
As users I have myself: deonh with no password required.

Drive A: Good & Drive B: Failed
I can access my NAS' UI by putting in the NAS' IP address in the browser.
It shows this message: RAID is still operational, but the faulty drive must be replaced to preserve your data. (What a relief.)
I bought a 4TB Seagate IRONWOLF NAS HDD.
I did the following yesterday morning: This drive I installed in B-slot after removing the failed drive after shutting down the NAS and removed LAN & Power cables.
I plugged in the LAN cable and right after the the power cable and the NAS started to boot up. (It doesn't have a power button.) It booted up and after a minute or so, the LED indicator turned groom green to amber to red. I understand the Red since the RAID failed. I left it until about 10:00 this morning with the light stil red. On the UI Drive be status: Failed.
I shut down the NAS through the UI and removed the new drive in bay B and powered it up again. I remember that I could access al my files on the NAS having mapped the NAS: \\mynasname\PC_Backups
When I only put \\mynasname in WIN file explorer, I see the four public folders which the NAS created when I initially setup the NAS. These I can access without a problem. But, I don't have any data there.
When I try to access my backed up files, I get this error: Windows cannot access \\mynasname\PC_Backups I need to access my files to save on my PC
I know it has to do with permissions. I need to access these files because I want to do a full Factory Restore since my NAS was not rebuilt in 24 hours.
I'm sure it has something to do with permissions and file sharing because I had to make some setting-changes when I got my new PC about 3 years ago.

I will really appreciate it if someone can help me solve this or help me get the B-Drive to take or whatever it is called the RAID from Drive A.

I read on a post that there is a chance that I can access the data with a cross-over LAN cable direct connection between my PC and LAN. But I don't have a cross-over LAN cable.

Please advise.
Thanks a million.

First and fore most use the IP instead of the domain name to try access it to make sure there’s no problem there.

If it was a simple mirror RAID pull the healthy drive out and stick it directly in your PC to get the data off, will be much faster too.

The NAS likely doesn’t want to serve the data until the RAID is healed with a new drive and full green status.

But also sounds like you’ve simply not had a workout configuration at all for a long time and might haven backing up into nowhere considering the factory folders show up.

Easiest is still to just pull the drive out and access it directly.

If it wasn’t a mirrored RAID then your data is gone.

Crossover cable has nothing to do with it and doesn’t even apply in the modern world. The UI works therefore connectivity works.

Thanks very much. I will quickly put the drive in my pc and check. Thanks.

Thanks very much for the reply.
I set is up as RAID1. I could access it through it's IP address.
I did as you suggested. What I noticed is that:
BIOS picked up the drive
Disk Management picked it up but no drive letter was assigned since there are a total of 5 partitions. Four of the four are healthy partitions and the fifth (smallest) is not available.
File Explorer did not pick up the drive
I r-clicked on the drive in Disk Management to see how it is formatted. Convert to MBR disk was greyed out which made me think that this is what it was formatted and "Convert to dynamic disk" was available.

I couldn't access the disk with data. I think I am going to put this disk back in Bay 1 and the new one in Bay 2 and power up the NAS and wait for 24 hours and see if it writes the NAS on the new drive.

I even used "Deep" AI to help me. I thoroughly explained everything and got this as a suggestion through command prompt:
net use Z: \\192.168.1.50\oldpc /user:test

Through the NAS' UI I set up a user as test and tried with and without a password and every time it said that it couldn't connect and that I must check spelling.

Thanks so much for your time. Much appreciated.

Update:
This is what I type in File explorer:


Both folders on the NAS show: I changed "oldpc" to also be as shared folder but it has a password.
When I clock on either of them, I get the message below:


It does't even ask for username or a popup to enter usename & password.

I think the problem is permission and I don't know where to look or how to fix it. I need to access "oldpc" to make a backup of the files before I fix the raid.

Any light on this will be very helpfull.
Thanks.
