IsoBuster is an unusually powerful data recovery tool that can rescue files from just about any optical disc.

The program works with all CD, DVD, Blu-ray and even HD DVD formats. In a couple of clicks it can be scanning your disc for lost data. And a deep understanding of many different file structures means that, if the files are still readable, there's a very good chance that they can be recovered.

There are also many convenient and thoughtful touches here. When you first scan a disc, for instance, IsoBuster will ask if you want to create an image of it on your hard drive (scanning that will be much faster). And in a welcome bonus feature, the program allows you to open many image formats, and browse them as though they were actually discs, viewing documents or launching the applications they contain.

There is also an important restriction with this version of the program: it can't recover data from UDF discs (UDF is the file system used by packet writing applications). To unlock this you must purchase an IsoBuster Pro licence; this costs $29.95 for personal use, and you can find out more on the IsoBuster site.

IsoBuster 4.2 includes these improvements (see changelog for more):

Changes / New:

Rewrote the options dialog to look fresh and most importantly te be decluttered and intuitive again. Added to that, selecting a language or changing a font now changes all options' text immediately, so that you can see the effect
Added BDXL, M-Disc, UHD, Triple Layer (TL) and (Quadruple Layer) QL BD(RE) disc support
Ability to start IsoBuster 'idle' without any drive auto-selected (not the default but can be set in Options)
Search (now by default) searches the entire region of the selected object, and not just the most relevant File System. For instance when a Session is selected, all tracks and file systems in those tracks will be searched and not just the most relevant file system in the most relevant track. The old way can still be turned on again in options
Work around for issue (most likely a buggy USB bridge driver) that causes less bytes to be transfered when reading raw (2352 bytes per block) on some systems
Ability to specify where the IBQ range ends, to influence filling gaps and where finishing at the end starts [Professional license]
Implemented more flavours of Rimage Image files (*.rmg)
Show text portions of certain Image files via an extra option in the main menu (e.g. for: *.cue, *.rmg, *.ewf, *.ccd)
Rewrote the file export / report functionality to make it much faster, 10 times faster or more than before
Rewrote CUE file parsing to better deal with multi-file images and improve the overall functionality
Support reading in the first pregap on a CD (addresses -150 to -1), for instance with Sector View
The Edit window / Sector Viewer can be set (and will remember) its own font for both normal text and text that requires a fixed width font
