I'm seeing rumblings that I'm not the only one here...mid-2015 MBP and upgraded to Monterey and immediately after upgrade my external USB drive (Time Machine) and SD card (in the lost) periodically unmount themselves, give a warning and then randomly remount. This makes these external storages unusable- Time Machine won't even engage in the updated, current state.
MacBook Pro 15″, macOS 12.0
I have no explanation for the differences in cables, I followed a suggested remedy that worked for me. Another user suggested trying certified USB cables. I looked at what was shipped with the drives (LaCie and WD), they had the correct stamping and labeling that indicates that they were certified. However, I bought two new cables, nothing fancy (Amazon basics and some other vendor called Plugable) with the USB-IF certification (like the old ones). I haven’t had a mounting problem since. My M1 mini seems to have delayed mounting, but they do mount reliably. Intel Mini 2018 i7 seems to be more consistent.
I have the same exact problem as Perryb. I have BaseIQ flush microsd card that has worked since 2015 when I bought my MacBook. Now with Monterey it is Ejecting...
I should say that I’m using the BenQI flush mounted adapter and have done since 2015 with different versions of MacOS, with no issues up until Monterey
Same thing here, It's freaking me out. I don't know why I upgraded, the Mac is full os bugs and it's being hard to work when everything behaves strangely.
I'm using the SD card slot =/

🤦🏻♂️
Guess that's gonna have to wait for an update from apple...
Monterey It's freaking me out!! my SD works fine until this D4MN upgrade. programatic obsolescence???
The internal HD is so tiny 250 GB, I need the 500 GB in the slot for media storage and photos. Apple, please fix this...
I would also like to add that Monterey is working great otherwise! Thanks
I also get the beach balls, freezes, and reboots. I don't have these problems on my BootCamp Windows 10 install on the i7.
I am using the cables that came with the Lacie and WD drives. I guess I can try picking up new cables and see what happens, thanks for the suggestion!
This does not solve the issue with SD cards
Thanks. I will try that. I'll go to Best Buy and grab a couple of USB-fi cables and see if that resolves it.
that may be the case for external hard drivers, but this also happens to older MacBooks with sd cards mounted to the sd slot. Think there are 2 issues on this thread
Thanks Oliver!
