So, I'm trying to perform my Macbook backup on my 3TB drive. This drive is currently has a GPT table with 4 partitions:
Before BackupMain, there are 3 free MiB, before BackupMac there are free 256 MiB and after BackupMac there are other free 256 MiB (I read around 128 MB were required after partitions, so for safety I wasted 512 MiB! :P )
BackupMain is NTFS, BackupKubuntu is EXT4, BackupWindows is NTFS, BackupMac is ExFAT, I thought it was usable but looks like I need to format to hfs.
Now, Disk Utility from OSX gets stuck (probably due to the Ext4 partition which it's not detected correctly). I need to replace BackupMac with a proper partition that can be used for Time Machine.
- What command line should I use? I currently found Create new partition in unallocated space with diskutil but it's a bit complicated because it's not my specific usecase (and doesn't say how to delete a partition first)
- If I use Time Machine to "Erase Disk", will it actually erase it or only the specified partition? Because the dropdown menu asks me to choose a partition, but then says "delete disk"
- Time Machine uses the same stuff as Disk Utility? Not interested in getting stuck, I prefer command line tools if that's the case
