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.

terminal disk utility

Is there any way I could add the remaining 750 GB to the existing partition disk2s2 or create a new disk2s3?

  • Welcome to Ask Different. I’m curious if the + is clickable in the bottom image - can the graphical utility add an HFS partition?

  • @bmike it is, but I think it's just using the free space from the partition. Image here: postimg.cc/qtKH9zcL Commented Oct 13, 2020 at 12:15

    Popa: Post the output from the command diskutil info disk0s2 | grep -e Offset -e Size. This will show where the container resides on the drive. Commented Oct 13, 2020 at 19:04

Ended up formatting the whole thing after doing a back-up
