I have a 2T USB 3.0 external drive. It was formatted to Mac OS (Journaled) filesystem. But after I did something wrong in a partitioning software in windows, this disk is no longer partitionable in mac.
The problem is, now the disk is still usable, it has a 1.5T and a 300G partitions, but it is not partitionable, that I cannot adjust the size of these 2 partitions or make use of the unused 200G. I cannot even delete the 300G partition. In short, the partitions are FIXED in there.
I don't wanna erase the whole disk, because I currently don't have any other disk that large to backup my data, is there any app or any way to solve this partition problem?
