Unable to retrieve last logical volume descriptor #64

Open jthomme1 opened 10 months ago

jthomme1 commented 10 months ago

Hello, I am trying to use your tool to access a FileVault2 partition.

I have the EncryptedRoot.plist.wipekey as well as the password.

But when trying to access the volume from Linux, I get the following:

$: sudo fvdemount -v -e EncryptedRoot.plist.wipekey -p redacted /dev/sdc2 /mnt/tmp
fvdemount 20231029

Unable to open: /dev/sdc2.
libfvde_encrypted_metadata_read_type_0x0305: unable to retrieve last logical volume descriptor.
libfvde_encrypted_metadata_read_from_file_io_handle: unable to read metadata block type 0x0305.
libfvde_internal_volume_open_read: unable to read encrypted metadata 1.
libfvde_volume_open_physical_volume_files_file_io_pool: unable to read physical volume files from file IO pool.
mount_handle_open: unable to open physical volume files.

Do you have any clue what could be the problem?

I am thankful for any hints.
