I bought this WD NAS over ten years ago and it has ran fine up until about six weeks ago
when it died. Windows 7 just no longer sees the mapped out drives in My Computer. There
were no sounds coming from the spinning drives just nothing. So I decided it was a WD
enclosure problem and not a hard drive problem. So I pulled the hard drives from their
enclosure and connected one of them to a “USB to SATA Adapter”, then plugged it into my
computer. The computer made a sound of a USB device being plugged in, but nothing
showed up in My Computer window. My conclusion is that I would have to look elsewhere
for my answer if I wanted my data back.

So I started my research on the internet, and found there are a lot of people with the
same problem and no support or fix from WD to correct it. I found that some people had
success with Linux. I have an older DELL laptop laying around so I loaded Linux Mint 20
“Ulyana” – Cinnamon (64-bit) on to this older DELL. I can at least see the drive now in
the My Computer window but can’t get into it. When I try, I get the error message “Unable
to mount location”.

In the past six weeks I have read and tried countless internet posts, most of them have
been Terminal Window stuff without any success. I know there is a solution out there, I
just need someone’s help to find it.

If you are willing to take on this challenge, you will find that I’m highly motivated to
retrieve my data. I promise to check this forum every day and try your suggested key
strokes and post results.

Shown below are two looks at both drives “Disks” & "sudo fdisk -l". I’m hoping that if
someone is willing to help me this will be useful to you.

Thank You in Advance

If you would like to read more background of my problem I'm facing please look in section 3 for "TSQMAN-1" on this forum.

I have tested your posting and the results are shown below do you anymore suggestions?

QUESTION for you: It looks like it had a problem with STEP #5 & STEP #7, where does the "/dev/md4" come from?

Thank You in Advance
