Am I doing this right?

#1 Post by lonrot » 20 Mar 2015, 19:22

I'm trying to recover a single 4 TB ExFat partition made in Maverick's Disk Utility.

This single partition on the disk has storage files shared between Windows and Mac.

It became inaccessible after a Windows performed a repair reboot on the main hard drive.

Here's what TestDisk has found:

1) Disk selection (Note: disk0 and rdisk0 have the same size!)

2) EFI GPT detected on Disk0. Is this okay for an exFat partition?

3) MS DATA found! The sector size reflects the 4 TB storage. Is this a green light?

In Advanced, select the partition and choose List or Undelete or Boot/List.

You can try

Code: Select all

sudo fsck.exfat /dev/disk0p1
or something similar

Christophe the partition is back, however Windows mistakenly tried to "repair" the hard drive during boot, and now it shows up as a Windows primary partition even though it does not have an OS.

Is there a way to get rid of this leftover MBR data and remove the drive from the boot list?
