new to linux, question on the dd command


Hi, basically my question involves the dd command. My aim is to copy the entire contents of my usb thumb drive (e to a folder located in (c:myfolder). I have seen a tutorial on this site for dd, which is helpful but no matter what i have tried i dnt seem to be able to get it to work successfully. Im using a windows machine and i downloaded 'cygwin'. Could anyone help me out here?


Thanks

Using cygwin, you don't have a kernel. The cygwin shell sits on top of windows, so you use windows for access to devices. If you need an image of the thumb drive, then either plug it into a computer running Linux, or boot up with a live distro on the current computer.

There are unix utilities for windows (win32) and dd is included.

I have never used these utilities and do not know how well they work.

Windows not only abstracts the hardware, it prevents users from accessing the hardware directly. Contrast this to Linux, which abstracts the hardware, but does allow users to directly hit the hardware, if they really want to.

Two different philosophies, and I'll argue in favor of either of them, depending on the mood I am in.

But the upshot, I think, is that dd is unlikely to work in a Windows environment since it hits the hardware at a pretty low level. I am not positive of that and I have never tried dd from cygwin, but given that cygwin hooks into Windows at a fairly high level using a dll, this is what I would expect.

I would suggest, as someone else suggested, that you make an image of the thumbdrive using a Linux system then copy the image over to Windows.

ok, but in my situation imaging the thumb drive on a linux machine is not an option (unfortunatly), i need to find away to image the thumb drive on the windows machine - maybe i should head away from the dd image idea - are there anymore options for creating an image?
