This same thing is happening to me. I was previously using a late 2013 MacPro (trashcan) with a Pegasus2 R4 8TB unit. Worked flawlessly for almost 8 years. My Trashcan is running Catalina (10.15.7). I just received my new M1 Max macbook (Monterey 12.0.1) and experienced these same ejections. At first I thought it was because of the sleep / power saving settings but after adjusting those to never go to sleep, never go to screen saver, and never put HD to sleep, the issue persisted. Even worse, the drive ejects *when I'm copying files from it to the macbook's internal drive*. This happens 100% of the time, making the drive unusable on the macbook. I hooked it back up to the MacPro Trashcan and it works fine. I also have been using a client's Pegasus32 R4 unit and it has the same issues. Firmware on my drive is up to date, the firmware on my client's drive is not. After some googling, these issues seem to be very common in Big Sur and Monterey. Promise has been responding to my ticket but so far we've just reached the standard troubleshooting questions of "have you tried different cables and ports, etc.". I'm on day 3 of back and forth with support and still no resolution. Luckily I can still use the drive on my Trashcan but unless this gets resolved I'll have to look elsewhere for a new unit because this is not cutting it.
