Hello guys
Has anyone worked before on Caine??
Actually I have a problem in mounting a usb device.
The OS is booted from a bootable CD.

so what???

what do you expect now? You gave almost no information, there is no question...

I work on Caine, an investigation linux operating system and I've booted it from a usb.
In this os there is many GUI programs, guymager is one of them which allow you to take a clone or a dd image for drives or partitions. when I try to execute the operation (iumaging or cloning) after choosing dest and source drives, an error message appears: "there no permission to access the destination drive (a usb external volume), and after that i knew that it wasn't mounted.
How can I solve this problem: mount the volumes and achieve the imaging process???

My first thinking is that you need to be superuser.

I'm unfamiliar with this operating system, but it sounds like the point of it is to enable these types of features, and therefore one would think that they'd take care of privileges as part of all that instead of leaving you unawares.

I don't recommend using a GUI to perform some of the advanced such as this, and you don't need to do that for dd.As an example, say I wanted to copy an entire disk, my original disk has maybe two partitions, and it gets mounted as /dev/sdf1 and /dev/sdf2, but I want an entire disk copy. My target disk gets mounted as /dev/sdg1. Well, I'd invoke dd from the command line the following way:I know people use the bs= part of the command, but honestly I've never been bitten by not using that option.

I repeat, don't use a GUI based tool to perform this type of operation. Just my opinion there.
