transferContent: use mmls to check on partitions

[shallcro]

First check: are there partitions?

If no, then use disktype

if yes, then need to consider which tool for which partition

• Maybe create a dictionary of values from disktype (can include sector offset)
• Then use this dictionary to determine which tool to run..
• Disktype has added valued of indicating filesystem with standardized

Create separate directory for each partition; loop through dictionary until it's all done

Key elements to track and automate process:

• info_package: partition or filesystem;
• file_system:
  • declaration (FS)
  • file system type (note; may have more than 1--as with CD-ROMS)
• partition
  • declaration (partition)
  • partition number (needed by unhfs; use values in mmls--start with 0)
    • NOTE: If there is only 1 partition with a file system, then we don't add a 'partition' folder?
  • Filesystem type (parse out from disktype--i.e., _file_sysline.split(' file system', 1)[0]) -This will determine whether we use tsk_recover or unhfs
    • NOTE: have to verify that partition includes a filesystem; partition maps will not include files--will need to verify existence of 'file system' string
  • sector offset: parse from mmls? would need to be padded... if from disktype

First attempt:

• make a list out of disktype output
• find out where partition occurs: indices = [i for i, x in enumerate(mylist) if 'Partition' in x]

Gets info in a dictioonary--could then parse through

newlist = []

c = 0 for part in mmls[5:]: ... tempdict = {} ... if any(x.isdigit() for x in part.split()[1]): ... tempdict['part#'] = str(c) ... tempdict['start'] = part.split()[2] ... tempdict['fs'] = part.split()[5] ... newlist.append(tempdict) ... c += 1

ISSUE: partition type is also split...

[shallcro]

This does a better job:

import re

for part in mmls[5:]: ... print(re.split(r'\s\s+', part))

['000:', 'Meta', '0000000000', '0000000000', '0000000001', 'Primary Table (#0)'] ['001:', '-------', '0000000000', '0000000127', '0000000128', 'Unallocated'] ['002:', '000:000', '0000000128', '0000016511', '0000016384', 'DOS FAT12 (0x01)'] ['003:', '000:001', '0000016512', '0000082047', '0000065536', 'DOS FAT16 (0x06)'] ['004:', '000:002', '0000082048', '0000213119', '0000131072', 'Win95 FAT32 (0x0b)'] ['005:', '-------', '0000213120', '0002097152', '0001884033', 'Unallocated']

Now,:

• Check Disktype to identify UDF or ISO9660 disks (Send to teracopy)
• Then check mmls description
  • 'osj', 'HFS' , or 'Apple': send to unhfs with partition #
    • other: send to tsk recover (need start point and partition #)

NOTE: fiwalk starts numbering partitions @ 1 (not 0)
