I'm in the same situation as Recover deleted Encrypted OS X Extended volume

but the recovery process did not work, understand there still a potential way to fix this but I need to view part of the disk.

This is a big drive 24TB

After accidental FAT32 partition.

Did not ask me for password and nothing shows up with diskutil cs list other than my main drive.

Attempted to comment on original post but do not have enough reputation.

These are the commands I used:

diskutil umountDisk /dev/disk2
sudo gpt destroy /dev/disk2
diskutil umountDisk /dev/disk2
sudo gpt create -f /dev/disk2
gpt add -b 40 -i 1 -s 409600 -t C12A7328-F81F-11D2-BA4B-00A0C93EC93B disk2
gpt add -b 46874697688 -i 3 -s 262144 -t 426F6F74-0000-11AA-AA11-00306543ECAC  disk2
gpt -r show /dev/disk2
gpt add -b 409640 -i 2 -s 46874288048 -t 53746F72-6167-11AA-AA11-00306543ECAC disk2

I did make one mistake when doing this the first time and did

gpt add -b 46874697688 -i 2 -s 262144 -t 426F6F74-0000-11AA-AA11-00306543ECAC  disk2

"-i 2" instead of "-i 3" could have this messed up the drive, I have a bin backup that I can restore from?

Any addition details would be helpful, I have the password to the encrypted volume.

  • There is a small chance that the sizes of i2 and i3 are slightly different than the ones you have chosen, that a gap exists between i2 and i3 and that the start block of i3 is at a lower block number. It would require remote access (e.g TeamViewer) and a root account though (because I have to search for special hidden metadata with an app called wxHexEditor) to check/repair this. Permuting the index numbers (i2 <> i3) is no problem! That's just a position in the GPT. – klanomath Sep 29 '17 at 11:28
