This will list all the disks that Linux sees. This will not show loop devices. See `losetup` example for more information:
losetup -- 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 loop device for it and see its partitions with `fdisk` and mount those partitions individually with `mount`. Note that `fdisk -l` does not normally show loop devices. You must add an explicit path to the loop device that you want to list.
losetup /dev/loop0 disk.img fdisk -l /dev/loop0
The previous example assumed that /dev/loop0 was free. You can you the '-f' option to automatically find a free loop device. In this example we first use the '-f' option to associate the image file with the next available loop device; then we use the '-j' option to see what loop device was associated with the file:
losetup -f disk.img losetup -j disk.img
mounting partitions inside a disk image without loop device
It is also possible to mount partitions inside a disk image file directly with `mount` using the 'offset' option, but I have not had luck with this.
mount -o loop,ro,offset=1025 disk.img /media/adhoc
