MacOS Bug Sur can format drive but can't mount it I have an USB-stick and I can format the Stick but when I try to mount it following error occurs:
The error is on german, it means &quot;Mounting of &quot;Ohne Titel&quot; has failed. (com.apple.DiskManagement.disenter -Error -119930873)&quot;

I can't find any solutions online and don't know what to do.
There are no data on this stick so I can easily format it.
After a bit of &quot;googling&quot; I can see the problem occurs to other people too.
Try to follow the guide proposed below before you go a step further.

Just to reason a bit more on the problem: have you modified the settings of the stick via software or hardware ( e.g. moving an unlock button)?
This guys solved with a software different from Disk Utility, but I don't think it is necessary.
