I have the same issue on 2 year-old High Sierra installs that somehow stopped being able to read all 6 of my VeraCrypt devices, and I know these devices are healthy because I can still read them fine, mount, and use them with no issues on Ubuntu 20.04 and Fedora 33
Just dropped in to say that this is a problem somewhere in the OSX/macFuse/VeraCyrpt stack and not necessarily with corrupted devices.
As I said in the beginning, disks can (and will) fail at some point and so having other encrypted backups is very important. Data recovery is not a guaranteed process because it depends on the how much the disk was corrupted.
Mac no mountable file systems fix for mac osx#
There are also other Data Recovery applications for Mac OSX that you use but you should always point them to the unlocked disk image and not the encrypted physical drive. Select it, check that its size is coherant what and then you can use the Repair option to see if it salvage your data (see ) The disk will be unlocked but it will not appear on Finder.Īfter that, you can use OSX Disk Utility to try to repair the unlocked disk image (and not the encrypted physical disk): once Disk Utility opens, look at the bottom of the disks list on the left and you should see the unlocked disk image by VeraCrypt at the bottom. When mounting the disk, click on "Options" button in the password dialog and then check "Do not mount" at the bottom, type your password and click OK (see screenshot below). That being said, VeraCrypt offer possibility to help salvage data when possible. This is outside of control of VeraCrypt (one must not forget that disks always fail at some point and so backup is important. This error happens if VeraCrypt is able to mount the disk but the disk content is corrupted is such a way that OSX is unable to identify its content.
