I have a WD My Passport 4.0 TB USB with GPT partition, that was used in a 2013 MacBook Pro.
My Linux Mint 17 is "Unable to mount location Can't mount file". Linux Mint "Disks" shows the 4 TB drive as having GUID Partition Table, partition type Apple HFS/HFS+ and contents unknown. GParted shows it as having 3.64 TiB partition with unknown file system and another segment of space at the end as unallocated 1.00 MiB
I would like to recover the missing 0.35 TiB and then maybe install a partition my Linux can mount. What's on it now does not matter. I only want to use the drive for storage .
