Very impressive enclosure (mostly)

Bought this about 2.5 years ago, it was initially problematic but I was able to demonstrate to the startech technical support that it was defective and they shipped me a new one which works flawlessly. I did have to stop the disks spinning down though as it caused USB bus disconnects and as I'm using it as a raid 5 array I need it to be 100%. I am definitely very please with it as it's way cheaper than a NAS, I have it mounted on a Raspberry PI4B with UAS enabled and it's really fast, I have measured 30mb /sec write speeds on my 4 Toshiba P300 3TB array.

Constant disconnects

This constantly disconnects whether connected via eSata, USB 2.0 or USB 3.0. Is there a firmware update available? It is populated with two identical WD Enterprise class 4.0 TB drives model # WD4000F9YZ. I've tried all of the above connectivity options and the problem remains. I've tried locating the drives on different 'shelves' inside the drive and using only a single drive in the enclosure and the disconnect problem remains. Any help would be sincerely appreciates as this has been a long-term issue making the enclosure unacceptably unreliable. The O/S is Windows 10 Pro 64-bit version 21H1 O/S build 19043.1165 with all the latest patches as of this date 09/13/21. Please help!

Turn it on, nothing happens.

Turn it off and back on, maybe it will detect, turn it off try again. 1 - 3 tries, every time. It also disconnects, and won't reconnect, so I am constantly turning it off and on. It has 4 identical WD RED NAS drives in perfect shape. Works great when it decides to connect.
