Using TCT To Recover Lost Data On Linux Or Unix - Part Two

"Lazarus is a simple tool to run, but it does come with a few caveats:

1. Unlike unrm(not a double-negative ;), which only requires that you have 100% of the free space available on the partition where you deleted your file, available on your recovery partition, lazarus requires you to have 220% of that space available. These sentences are "killing" me! Apologies for any confusion caused by their Byzantine structure ;)

2. Lazarus depends on the output from unrm, so you'll need to run that first. Technically you can run lazarus against any file, but your results may be less than satisfactory.

3. Lazarus picks apart the gigantic block-file created by unrm and separates it into individual files and tags those files as being of a certain type (text, audio, HTML, C code, etc). This makes it take a very very long time to complete execution. Depending upon the amount of free space on the partition on which you deleted the file you wish to recover, you may be waiting days (literally) for lazarus to complete its work!"
