Disk not ejected properly

Question

Disk not ejected properly

Macpro 2019 running Ventura 13.0.1. I have two SSD's installed on OWC Accelsior S: PCIe to 2.5" 6Gb/s SATA SSD Host Adapters, a 500GB just for data backup and a 1T for Time Machine. Both SSD's began giving "Disk not ejected properly" errors about a year ago but after update to Ventura much more frequently and happens several times a day. These errors appear to occur when the computer is sleeping or during screensaver. Does anyone have a solution to this problem? I have adjusted energy saver settings to some recommendations in other threads to no avail. I have also reset the SMC and PRAM/VRAM. Thanks.

Thanks for your reply and that certainly would seem to fit the problem. I installed both cards/SSD's shortly after I purchased the computer in January 2020 and they worked fine for at least two years, when some infrequent disconnects began. The Ventura update a couple of months ago began the daily disconnects. I would wonder if my internal power supply might be losing something. My Applecare expires in two days on 12/13/22! Any ideas what I should do? Thanks.

I am thinking of removing the 500GB Toshiba drive and leaving only the Time Machine drive and maybe it would get enough power.

I have called OWC and they referred me to Apple. And I have called AppleCare and they weren't very helpful. The disconnect sure seems related to sleep. Both just got kicked off when I ran out to pickup lunch. Thanks again.

Many Bus-powered drives do not respond happily when their USB power drops during sleep.

If you can, connect an external power source.

My answer was based on my assumption that these were in EXTERNAL enclosures.

If on a PCIe card, you should contact OWC and ask them.

They pride themselves on their excellent Mac support.
