| Dec 19, 2017 at 23:20 | comment | added | Arne Burmeister | @jksoegaard hmm, maybe the stick was formatted from a Mac sometime before and then erased/reformatted on Windows later. You think this may not have overwritten all of the partition info? | |
| Dec 19, 2017 at 23:19 | comment | added | jksoegaard | Use a partition editor - I cannot remember if diskmgtmt.sys or fdisk on Windows will do it for this type of partition table. If not, you can most probably download a more advanced partition editor for free. | |
| Dec 19, 2017 at 23:18 | comment | added | jksoegaard | The formatting and mounting only takes place at the partition level. The partitioning table is stored at the disk level instead. Might it be that you've created the partiton table on a Mac, and then later chose to reformat a single partition on a Windows PC to use there? | |
| Dec 19, 2017 at 23:18 | comment | added | Arne Burmeister | @jksoegaard how to safely change the partition type without risking the data? | |
| Dec 19, 2017 at 23:16 | comment | added | Arne Burmeister | @jksoegaard it seems but: was formatted on a windows machine and also mounts there without hassle - looks like that information is wrong and I would wonder if the windows was able to create such. But I can check the windows info when I have access to tomorrow. | |
| Dec 19, 2017 at 23:13 | comment | added | jksoegaard | Your partition table seems to indicate that the partition type is Apple_HFS. This is why the Mac tries to mount it as HFS and fails. Can you check on your Windows machine if it displays the same in the partition table? (using diskmgmt.sys for example). Change the partition type to ExFAT and you should be able to mount the disk on the Mac as well. | |
