I'm trying to make a storage partition on my bootable Linux flash drive. It's using GPT and booting with EFI.
|------|-----------------| - - - - - - - |----------|------|
| EFI | Linux | (storage) | Recovery | Swap |
| 500M | ~28GB | 32GB | 2GB | 1G |
|------|-----------------| - - - - - - - |----------|------|
(Not to scale: EFI, swap, and recovery are much smaller. Recovery is a bootable Ubuntu Live CD installation.)
I used GParted to format the (storage)
partition to NTFS. Then I erased the volume using GParted. But when I rebooted to Mac, Disk Utility doesn't see the free space at all. I clicked Partition to try to reformat the volume, and got this:
Yes, it's really around 28 GB, as the number says...but the picture shows it taking up nearly the entire disk!
Before I deleted the provisional partition, it showed up but gave me a different error when I tried to reformat - something along the lines of "couldn't modify partition map".
