That suggests there's no partition, post output of:

 

fdisk -l /dev/sdl

The result of the first command you entered is what we need.

 

When I did it the the space and hit enter, All it did was give me a new unraid prompt.  I thought the space maybe was not needed so tried it that way as well.

Yep, there's no partition, I didn't go back in the thread, but are you sure this is the correct disk?

 

If yes, type 

sfdisk /dev/sdl

then type 64 and hit Enter

then hit CTRL+C to abort, don't type anything else, and post what you see.

It is the original removed disk, Only one I have.  Here is the output:

 

root@unRAID:~# sfdisk /dev/sdl
The backup GPT table is not on the end of the device. This problem will be corrected by write.

Welcome to sfdisk (util-linux 2.40.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Checking that no-one is using this disk right now ... OK

I used Diskinternals Linux Reader for Windows when I hooked the drive up via USB to my computer earlier this week.  All the files showed up on there.  However, That program is only meant to see the drive/data and nothing more.  Not sure if there is some way to get Windows to read the drive so I can copy and move the data over to a Windows PC.  Tried doing some research on google but some of the stuff doesn't make sense to me.

You can try recreating the standard Unraid partition, looks like it was what was being used, sector 64.

 

It won't make things any worse, type:

 

sgdisk -o -a 8 -n 1:32K:0 /dev/sdl

 

Then see if UD can mount the disk, if still not, best bet is a file recovery app, like UFS explorer.
