Can I recover in this scenario?

I have an older Western Digital Sentinel unit. It is a glorified headless NAS with Windows Storage Server OS that you can only access via RDP.

One of the 4 drives in the unit essentially died last week, and the Sentinel is now completely inaccessible.

It is made up of: (4) 2GB SATA HDDs in a RAID 5 array.

I have purchased (2) HDD caddies and have all 4 HDDs hooked up to my Win10 desktop now.

The 3rd drive is making strange sounds, and is not recognized in multiple programs such as R-Tools.

Had most of the data backed up, but there is about 500 MB to 1 GB I would like to recover if possible.

As previously mentioned, recovery software is not "seeing" drive 3, but the others appear to be OK.

Question is: would r-Tools be able to recover anything in this scenario?

1. Disconnect the failed drive. No sense to torture it, it will do nothing. If that is the only failed drive in the RAID5, the rest of the drives are enough to recover data.
2. You may try the scenario for free. What to do if I don't know if R-Studio can recover my files?.
3. Useful info:
