CHKDSK is the worst tool you can use when you want to recover data. The tool basically try to repair a damaged filesystem but deleting!!! damaged parts and files.
Sometimes it can be difficult to recover a TimeMachine-backup. This is the case for example if a drive has many bad sectors and heavy filesystem corruption or if a head was failing and we are dealing with a partial recovery.
There is always a possibility that some data lane is shorted and thatfor alway deliver a 1 or a 0 for some bit. This tool test files and images for that issue and help to diagnose that phenomen.
A RAW-recovery often end up with quite a big mess. Thatfor I wrote that small tool which sort all JPEG-images based on the date in the EXIF-data.
A lot of people will use Snap2HTML for that purpose but I personally don't like that Snap2HTML follows links and generates huge reports with the same files over and over again. So I wrote my very own...
From time to time I got drives with the filesystem-catalogue in such a bad shape that I don't trust just one tool to get all data. After running multiple logical recoveries you need to merge them into one final folder which you hand over to the client.
A RAW-recovery is basically guesswork of a tool and so it is no surprise that some tools does this in some cases better then others. This script allow to merge multiple RAW-recovery attempts and sort the files by the file-extension.
Since TRIM come into play I wanted to have a fast indication if analyzing an binary dump with tools like r-Studio or UFS would even make sence ... On Linux (where I use that one mainly) I can also check the device-files easyly before imaging the drive.
A easy tool for RAID-recovery training. This script allow you to generate "mystery-boxes" with unknown RAID-configuration to train solving such cases.
