New Software (PFR)

Our new Software released under Open Source license.

PFR is a cross-platform easy-to-use powerfull tool to recover broken files that caused HDD or Filesystem errors. Seemed very usefull recovering corrupted innoDB databases as well. 

Overview

Software is intended to recover files from a bad drive, written in pure C, by doing the following:

  • Unlike other similar softwares, default action is Fast Forward which is a 64K direct-copy and only fallback to Block Mining aka byte-to-byte copy when badblock found and for a short period as recovery necessary, this mechanism give insane recovery speed on huge files.
  • In recovery mode, there is an option to define max retry, which intended to probe [x] times the same sector to recover badblock, there is a little chance to succeed anyway. Also if the block could not be recovered the software will fill a specified character instead (default: 0x00) and continues read, this mechanism allows to partially recover the file.
