Recover unallocated disk space I would like to recover some unallocated (?) disk space on an external hard drive /dev/disk2 is 1TB but I only see a 250GB partition. Here is a terminal screenshot and a Disk Utility one.


Is there any way I could add the remaining 750 GB to the existing partition disk2s2 or create a new disk2s3?
Ended up formatting the whole thing after doing a back-up
