In fact, if we did not want to take advantage of the additional features of dcfldd, we could use the exact same arguments as before and would get the same results. Unsurprisingly, performing the same image acquisition that was done with dd using dcfldd is quite similar. The extended dcfldd functions, as well as base dd functions, can be reviewed by passing the -help flag to the dcfldd command. Most of the capabilities revolve around hash creation and validation, logging of activity, and splitting the output file into fixed-size chunks. However, dcfldd has some interesting capabilities that aren't found in vanilla dd. The dcfldd project forked from GNU dd, so its basic operation is quite similar. The first of these to be examined is dcfldd, created for the Defense Computer Forensics Laboratory by Nick Harbour. While dd can and has been used to acquire forensically sound images, versions of dd are available that are specifically designed for forensic use.

The bitmap output used different characters to code the block meaning. If the entries option is given then a directory and its If a directory is specifiedĪnd the all option is given then all blocks occupied by files and sub dirsĪre also shown. The node command requires an on the image and shows theīlocks allocated for the given file or directory. maps shows theīlocks allocated by the bitmap itself. The all command shows all allocations in the bitmap. The find command calls the block allocator and tells you what would be the Use the brief option to show only bitmap lines with contents.

The free and used commands show the unallocated/allocated blocks on The info command calculates the free and used blocks. It is also possible toĬreate a new image with different size in the pack step. System in a new image with the exact same contents. The command is useful to defragment and rebuild the whole file Repacking allows you to combine the unpacking and repacking operations xdfmeta MetaDB file and everything will be set as needed on Volume directory tree on your host file system and call xdftool’s packĬommand to create an image file from it. You can also use packing to master Amiga disk images: Simply create a The exact recreation of an disk image later on. With the volume’s directory tree, the meta info DB and optional bootcode andīlkdev files in place you have everything on your host file system to allow Holds the disk geometry of the original HDF file. This holds the boot code that is required to make the disk bootableįinally, for HDF images a file called. If the disk image is bootable then a file called. Of the image an entry line is created that states the file or directory nameįollowed by a colon and the meta infos: protection flags, modification time Including volume name, dos_type, and the root time stamps. In the header line meta infos of the volume are stored These missing meta infos are stored in a MetaDB file called Still missing are the meta infos available in the Amiga disk image but notįound in the host file system: protection flags, comments and modification The contents of the files is also readily available. The host file system now contains the directory tree with all files andĭirectories. System structure starts with a directory named after the volume.
Unpacking a disk image means that starting from the volume’s root allĭirectories and files contained in the image will be extracted to the hostįile system and the same directory tree will be recreated. With the chs option or guide the detection algorithm by giving a sector In this case you can either fully specify the disk geometry xdftool has an algorithm to determine theĭisk geometry automatically from the byte size, but this approach might failįor some setups. The chs or h and s options are useful for HDF images without RDB Partition (startin with 0, of course!) or give the device name associated You can either give a number selecting the n-th Only work on a single partition or file system and thus you must select which

In thisĬase the image holds a full disk with multiple partitions. The part option is useful if you access a RDISK or RDB hdf image. Values then you specify the open command explicetly.
If the parameters can’t be detected or you don’t want to use the detected In this case all parameters for opening the input Most often you do not need to specify this command as it will be automatically The first command in a command list as it allows all other commands to work on This command opens an existing image for further processing.
