Default Mount Parameters Dialog

Make your modifications and then click OK.

The chosen values are then written to VeraCrypt main configuration file (Configuration.xml) making them persistent.

Under Linux, default filesystem mount options can also be specified in the Mount options field. For example, entering noatime makes VeraCrypt pass this option to Linux mount -o for subsequent mounts. These defaults can still be changed for an individual mount from the password dialog's Options button.

All subsequent password request dialogs will use the default values chosen previously. For example, if in the Default Mount Parameters dialog you check TrueCrypt Mode and you select SHA-512 as a PRF, then subsequent password dialogs will look like:

Filesystem mount options under Linux

+

Under Linux, the Mount Options dialog also contains a Mount options field for filesystem mount options. The value entered there is passed to the system mount command with -o when the filesystem inside the VeraCrypt volume is mounted. For example, entering noatime prevents Linux from updating inode access times on filesystems that support this option, reducing metadata writes caused only by file access. Multiple options can be specified as a comma-separated list, for example noatime,nosuid,nodev. Unsupported options are handled by the operating system and may cause mounting to fail.

The command line equivalent is veracrypt --fs-options=noatime <volume> <mountpoint>.

Mount volume as read-only

When checked, it will not be possible to write any data to the mounted volume.
