Welcome to the new Linux Foundation Forum!

use ubuntu to clone a windows hard drive with ntfs

tryed

sudo ddrescue /dev/sda /home/custom/user/sda_image.img /home/custom/user/logfile

problem is would not mount under /mnt to see if it worked

so tryed

sudo ddrescue /dev/sda /home/custom/user/sda_image.iso /home/custom/user/logfile

the sda_image.img file is 55gb the other one tht is .iso is 0gb

so now trying

dd if=/dev/sda of=/home/custom/usr/sda_image.iso

waiting to see what is going on any body got any advice on how to make the image work?

    Instead of cloning the entire harddrive, you could clone a particular partition (lets say /dev/sda1) to a disk image by running
    sudo dd if=/dev/sda1 of=/path/to/file.img
    

    If you're unsure about the name the kernel has given the partition you wish to clone, you can check the output of fdisk:
    sudo fdisk -l
    

    After creating an image of a partition as described above, you can then create a mount point for it by running e.g.
    sudo mkdir /mnt/image
    

    You can then mount the image to the dedicated location by running the following command:
    sudo mount -o loop /path/to/file.img /mnt/image
    

    If you cloned the entire harddrive (e.g. you used /dev/sda instead of /dev/sda1), I'm not sure how you would go about mounting the partitions directly inside Linux, since the mount command above only works when you clone a filesystem, not an entire disk. One way to verify that a full harddisk image works could be to load the disk image in a virtual machine, e.g. VirtualBox or QEMU.
