How do I rename a mounted Truecrypt volume?

Question

When I mount the Truecrypt file on my USB drive it shows up as truecrypt1.

The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1.

Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend".

Apparently this can be done in Win, but how can I rename this volume in Ubuntu?

As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu.

#!/bin/bash
gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

Solution 1

You need to create a mount point in order to do what you want. If I want my truecrypt1 volume to show up as "Private", I'll create a "Private" mountpoint with sudo mkdir /media/Private Then launch Truecrypt, select my encrypted drive and when I click on "Mount" I'm asked for my password and I can click "Option" to select my custom mount point. Voilà, it's done.

Solution 2

The prior solutions did not work if you have ext3/4 volumes. This is a solution for that case:

1. Find the ID using >> sudo fdisk -l

Disk /dev/mapper/truecrypt2: 128.8 GB, 128000000000 bytes 255 heads, 60 sectors/track, 15000 cylinders, total 250000000 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x1234567

Find the ID (bolded above) for the volume of interest. Your location WILL be different!

1. Use e2label: >> sudo e2label /dev/mapper/truecrypt2 newname

Again, make sure you use YOUR drive information.

I've been wondering how to do this too!

Although this does not set the encrypted volume label, this is a good alternative that achieves the same result. Thanks! :-)
