Paul,

Your linux filesystem is mounted and you are using md5sum to hash the logical 
drive? In EnCase your acquisition image is likely to be a hash of the physical 
device rather than logical.

However, the explanation may be simpler than this. Are you certain that md5sum 
is working in binary and not text mode as it reads from either the logical 
mounted device or from the raw physical device? Check the command line 
parameters to md5sum.

Regards,

Jason Coombs

Hello,

How can a same physical disk can receive a different hash (MD5) 
from EnCase and Linux md5sum ? (both through a drive lock) ?
Does smb meet this question ? Thanks.
