Hi there,
here you are my last instance - I have been trying to solve it in truecrypt forum, also in google but I havent found any solution and tc forum is mostly sleeping.
So my problem:
I have file which encrypted by truecrypt. It has two volumes - visible, hidden. To mount visible volume, there is no problem. When I try to mount hidden volume, I get “Error: mount: you must specify the filesystem type”.
I was trying to mount with option --filesystem=none, it seems it is mounted but I cant find it anywhere although I specify mount point. The volumes are in vfat.
Please, any idea how to correct and get data?
Thank you,
Martin

If it’s vfat, you can’t use --filesystem=none, because then you’re
telling it it doesn’t have a filesystem.
What happens if you mount it using the GUI application (or is it a
headless server?)

Hello Jim,
if I use GUI I just get the message "Error: mount: you must specify the filesystem type " so I have been trying to search for another way - for hidden volume. For visible it works correctly.
And on one Gentoo´s website was the way how to mount it manually with this option. And if I do it so I can list all mounted devices and it shows me that my hidden disc is mounted in slot 1 but I cant find mount point, nor with mount point specified in options of truecrypt command.

So let me see if I understand correctly - you have a setup that has a
hidden volume and a standard (outer) volume. The outer volume mounts
fine, but the hidden volume doesn’t.
Have you mounted the outer volume and written data to it without
protecting the hidden volume from damage? If you did this (and didn’t
protect the hidden volume from damage), then it’s possible you overwrote
some critical data in the hidden volume that’s preventing the hidden
volume from mounting.
I’ve used truecrypt a little bit myself, and what you describe sounds to
me like damage to the hidden volume.

You understand well…I copied some files to standard volume - I hadnt idea I should protect hidden volume…
Any chance to correct hidden volume and get at least some data?
I have Truecrypt & I can tell you from personal experience:’( it’s gone!:’(

Yeah, that’s the only way to ensure the hidden volume isn’t overwritten
when the outer volume is modified.
> Any chance to correct hidden volume and get at least some data?
If you backed up the hidden volume header then there’s a chance you might
be able to recover some data - otherwise, the chances are so low as to be
nonexistent. The beauty of encrypted filesystems is that there isn’t a
backdoor. The problem with encrypted filesystems is that if the
information used to encrypt the filesystem is corrupted, there’s no
backdoor to be able to recover any of your data.

I have in my mind only not publicable words… and for this no backup … in any case, thanks for your help.

Understood completely - this is one reason I haven’t used truecrypt for
partitions in general at this stage, just for USB flash drives and the
occasional file “container”.

Glad I could at least get you to the end of the issue, even though the
outcome wasn’t desirable. Having lost data myself, I know what you’re
going through…

Hi,
Run your installed copy of TrueCrypt. The application version must match the driver version.
It sounds like you installed 6.0a, and have the USB key set up with a traveler copy of TrueCrypt, which is what you double clicked on. Thats what produced the error.
Start the TC application installed on your system (start menu shortcut or whatever) then attempt to mount the TC container on the USB stick and you should be just fine.
