If you want to do recon without mounting then list the partitions with 'fdisk -l' or use 'disktype' (http://disktype.sourceforge.net/doc/
). Disktype also displays details like if the partition contains a (and which) bootloader, partition UUID, volume name or label, blocksize, size in human readable format and sectors, etc, etc. Indispensable tool for people who work with "unknown" disks a lot.
