The detail partition command should show the incorrect partition type value of 48465300-0000-11AA-AA11-00306543ECAC. If not, then make the appropriate substitution. This will correct the error in the partition table.īelow I assume the USB stick (flash drive) is disk number 1. You could goto back to your machine running Windows, open a Administrator Command Prompt Window and enter the following commands. Microsoft Windows will not care, but Apple macOS does.Īlthough, you do not show this in your question, the GUID for this type of partition is 48465300-0000-11AA-AA11-00306543ECAC. Therefore, the partition table has partition type error. What should have appeared is Microsoft Basic Data. In your question, the output from the diskutil command shows the ExFAT formatted partition to be Apple_HFS. Therefore, Windows generally does not look at the partition type, but rather looks at the content of the partition to determine the file system. For example, both the ExFAT and NTFS files systems map to the same partition type. The mapping from a partition type to a file system is not always one-to-one.
Usually, but not always, this is a file system. The type indicates what the partition will contain.
Any idea what to do without reformatting and loosing the data on the stick? Is there any option to manually mount the filesystem as exFAT using command line?Įach partition on a drive is assigned a type. I have no idea why the volume is not mounting correctly. Running fdisk tells: bb-8:~ arne$ sudo fdisk /dev/disk2ĭisk: /dev/disk2 geometry: 7651/255/63 Or from command line: bb-8:~ arne$ diskutil list
Instead the disk utility tells me it contains kind of Mac OS extended file system (German, sorry) but unable to mount (also information looks strange): My MacBook Pro running MacOS 10.13.2 cannot mount it. The stick mounts without any problems on a Windows 10 system. I got a 64GB USB Stick formatted as exFAT from Windows containing a lot of files.
