===Purpose===
 
−
Display  the  layout  of  media  management systems (partition tables)
 
−
mmls displays the layout of the media management systems, which include partition tables and disk labels.
 
−
<br />Namely, it will show which sectors are not being used so that those can be searched for hidden data.  It also gives the length value so that it can be plugged into ’dd’ more easily for extracting the partitions.  It also will show BSD disk labels for Free, Open, and NetBSD and will dis-play the output in sectors and not cylinders.  Lastly, it works on non-Linux systems.
 
  
−
===Usage===
+
mmls displays the contents of a volume system (media management).  In general, this is used to list the partition table contents so that you can determine where each partition starts. The output identifies the type of partition and its length, which makes it easy to use 'dd' to extract the partitions.  The output is sorted based on the starting sector so it is easy to identify gaps in the layout.

The <b>Slot</b> column lists where this partition is described in the volume system table. The contents of this column are volume system specific, but here are some general entries:
 +
* ##: A two digit number is used with volume systems that have only one table and the number corresponds to the entry in the single table.
 +
* ##:##: This format is used with volume systems that have multiple tables (like DOS partitions). The first two numbers correspond to the table ID and the second set of numbers correspond to the entry in that table. 00:01 is entry 1 in table 0.
 +
* Meta: This is used to describe an entry that is created by TSK to show where metadata structures are located. Meta entries can be suppressed with flag options. These entries are not in any volume system table, but maybe helpful to the user.
 +
* -----: This is used to identify an entry that is created by TSK for unallocated space.
 +
 
 +
The <b>Start</b>, <b>End</b>, and <b>Length</b> columns describe the starting, ending and length of the volume (in sectors). The final column is a text description of the volume.  Sometimes this is directly from the volume table and other times it is created by TSK.

mmls displays the contents of a volume system (media management). In general, this is used to list the partition table contents so that you can determine where each partition starts. The output identifies the type of partition and its length, which makes it easy to use 'dd' to extract the partitions. The output is sorted based on the starting sector so it is easy to identify gaps in the layout.

Output Example

The first column lists the Sleuth Kit assigned partition id.

The Slot column lists where this partition is described in the volume system table. The contents of this column are volume system specific, but here are some general entries:

  • ##: A two digit number is used with volume systems that have only one table and the number corresponds to the entry in the single table.
  • ##:##: This format is used with volume systems that have multiple tables (like DOS partitions). The first two numbers correspond to the table ID and the second set of numbers correspond to the entry in that table. 00:01 is entry 1 in table 0.
  • Meta: This is used to describe an entry that is created by TSK to show where metadata structures are located. Meta entries can be suppressed with flag options. These entries are not in any volume system table, but maybe helpful to the user.
  • -----: This is used to identify an entry that is created by TSK for unallocated space.

The Start, End, and Length columns describe the starting, ending and length of the volume (in sectors). The final column is a text description of the volume. Sometimes this is directly from the volume table and other times it is created by TSK.
