The output file (myimage.img) is around 8GB which is the normal operation of dd. Now when I dd my USB hard drive via: dd if=/dev/sdb of=myimage.img bs=1M dev/sdb2 55 83 basically my FAT partition is around 70 MB, ext2 partition is around 740MB and rest of the space (~ 7 GB) is unallocated. I/O size (minimum/optimal): 512 bytes / 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes I have 8GB USB drive attached to my system which looks like this: fdisk -l /dev/sdbĢ55 heads, 63 sectors/track, 1028 cylinders
