This will list all the disks that Linux sees, including any hot swapped drives that may have just been plugged in:
mount individual partitions in a whole disk image
If you have a while disk image and you want to mount partitions inside that image then use `losetup` to create a loopback device for the image.
For example, if you copied an entire disk using `dd` like this:
dd if=/dev/sda of=disk.img bs=32768
You can later create a loopback device for it and see its partitions with `fdisk` and mount those partitions individually with `mount`.
losetup /dev/loop0 disk.img fdisk -l /dev/loop0
