Although not strictly for forensic purposes, '''visualization tools''' such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.

==Programming Languages and Developer Toolkits==

A '''hard disk drive (HDD)''' is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
If you are building forensic tools, you probably want to start with one of these:
+
; Java and Swing
+
: Advantage: Portable and lots of good documentation out there.
+
: Disadvantage: Programs are a bit verbose, and only offers about 1/2 the performance of C
+
  
; Python with tkinter
+
== Data Recovery ==
: Advantage: Portable
+
: Disadvantage: Python is one of the slowest modern languages around.
+
  
; Python with wxWidgets
+
* [[Recovering bad data]]
: Advantage: Portable and a better development environment than tkiner
+
* [[Recovering Overwritten Data]]
: Disadvantage: wxWidgets is not installed by default, so you'll need to get it installed. Not as well documented as Tkinter
+
  
; [http://www.pyside.org Python with Qt (PySide)]
+
== See Also ==
: Advantage: Portable and a better development environment than tkiner or wxWidgets
+
: Disadvantage: Though not difficult, PySide has to be installed separately
+
  
; [http://processing.org processing.org]
+
* [[Hard Drive Passwords]]
: Advantage: Programming language specifically developed for visualization; compiles to java byte code
+
* [[DCO and HPA]]
: Disadvantage: Very oddball
+
* [[Advanced Format]] - the move to 4K sectors, and problems with Windows XP
  
; JavaFX - Java's version of Flash

; Flash
+
* [http://www.deadharddrive.com/ My Dead Hard Drive story or How I restored my save games]
 
+
Or you could try one of these higher-level toolkits:
+
 
+
; Crystal Space 3D
+
 
+
; Panda#D
+
 
+
== Applications ==
+
Most of these are scriptable.
