I've accidentally encrypted my 8GB usb stick instead of my 4GB stick and now I need to revert the encryption on the 8GB one. There doesn't seem to be an option like this in the TrueCrypt interface when I mount the USB.
Anyone know how to do this?
Based on how long it takes to encrypt certain volumes, my guess it will take ages to remove the encryption.
I highly recommend you simply mount the volume then copy everything off of it, format the stick and then move the items back to it.
Since you've said you already have your files saved elsewhere, all you need to do is delete the TrueCrypt volume and then re-format the USB stick. If you mount the USB stick (not the TrueCrypt partition), then you can simply re-format that and the TrueCrypt encrypted partition will just go away.
Alternatively, you can use
