[parted-devel] how to create compatible msdos partition tables?

[Harald Dunkel]

Hi folks,

I tried to set up a new msdos partition table on a USB SSD using
parted on Linux, but it was no recognized on both MacOS and
Windows 11.

Maybe a stupid question, but how comes?

After initializing the SSD on MacOS it was accepted on Linux as
well, so I wonder if it would be possible to increase parted's
compatibility to others?

Below you can find the parted session on Debian to "break" the
partition table set up on MacOS again. After that the disk was
rejected on MacOS and had to be reinitialized.


Regards

Harri
