How do you change the size of logical disks under OS X without losing data?

Question

macOS

Greetings, tell me what you use to work with disk partitions under OS X?

The task is simple - there is an external drive with one FAT32 - you need to either convert it to NTFS (or HFS - but then with the ability to do the opposite), or, which is preferable, create another partition instead of free space.

diskutil resizeVolume disk2s1 limits gives "Volume format does not support resizing"

iPartition which comes up first in Google is also nothing.

You can, of course, have a disk with Linux, it will boot - but firstly, it’s not entirely clear where the disk is now at home, and secondly, it’s somehow hard.

Is there an easy way?

It's still just an external drive, but I don't want to break the system one (by the way, I would also like to).

Answer 1

As far as I know, only Windows can do data lossless conversion from FAT to NTFS. There are pluses - any Windows can do this, starting with Windows 2000, that is, you can boot from a Windows XP LiveCD and perform the conversion. You can do the same without rebooting by starting the boot from the CD image in the virtual machine

Leave it as it is. Mac OS X without add. drivers are not able to write NTFS. Well, Windows can do nothing at all, except for FAT / NTFS and spoil other partitions with foreign file systems.
