I made a full disk image with 'DD' of a 64GB usb. Of course, there were some free space.
I moved/copied pasted the file created with the 'graphical interface'.
Now the file is only 50GB (I guess it didn't copy the free space)
I tried to mount it with 'kpartx' and 'losetup' and I see an error saying the disk is smaller than expected.
I guess this is because of the copy-paste made by the graphical interface.
Am I true ? I am just trying to add some zeros at the end in order to extent to more than the real size because now, I cannot access to my files because I cannot mount the partition.
Thank you.
