MacBook Pro M3 Max Randomly Ejecting All External SSDs

This is the very worst. How could this be happening!? I just upgraded from an intel chipset and it handled the same hardware without issue. This is screwing up my sessions.

I’m having the same issue, and it’s caused data corruption for me and loss of data. This is unexpected and unacceptable, I started having issues originally with a Crucial x10 4TB. I moved to a more expensive Glyph 4TB NVMe (TB3/USB3), and the issues persist right out of the gate.

Did a clean install of Sequoia seemed to work nice under the chipset. This is a very problem for my work. A very serious problem no one at Apple is addressing.

I Know this is a Macbook thread but FYI my Mac mini m4 Pro is doing the same.....fuming!!!

Hi,

If your external drives are bus powered, it may be your MacBook Pro USB-C ports couldn't charges good enough power for external drives.

Try to connect external drives via self Powered USB-C to USB-A hub.

I am a composer who relies heavily on my Apple computer for my professional work. Having been a loyal Apple user since 1984, I am truly shocked by the issues I am currently facing with my new M3 Pro 18Gb. Specifically, Safari appears to cause frequent disconnections of my hard drives, an issue I’ve never encountered before. My workflow is severely disrupted as a result, with five separate hard disks now disconnecting multiple times a day. This is an unacceptable inconvenience. Starting my computer with these drives connected has become impossible. The frustration and disappointment this has caused cannot be overstated. I can’t believe immediate attention to resolve these problems hasn’t been taken.

Has anyone found a solution to this problem? I've tried a Crucial x10 Pro 4TB and a Samsung T7 4TB and they both have the same problem. Has anyone tried an externally powered USB-C drive to see if that works?

Thanks.
