Stopped working on MacOS Big Sur

[devcybiko]

It keeps ejecting itself and I keep getting messages that it hasn’t been ejected in a proper fashion. It’ll work for 5-10 minutes then disconnect.

I just moved from Intel MBPro to M1 MacMini w/ Big Sur. Not sure if it’s the Mini or Big Sur or if my drive is at fault.

Happily, all this data is in the cloud, so I can afford to lose the drive. But I need it as a case-sensitive volume.

Anyone else have this problem or can offer suggestions?

I have the same problem I think,
I recently purchased a SanDisk Extreme PRO SSD 1Tb (2000MB/s)
I’m in MacOS Big Sur , When my macbook pro becomes in sleep mode.
The SanDisk Extreme PRO stops working until I eject and then reconnect SSD to computer
This is very annoying and sometimes I lose what I’m working on

Same issue

[devcybiko]

The solution for me was to upgrade to the latest version of Big Sur
