recovering-deleted-files-with-photorec

Run photorec against a forensic image or device, select the partition and filesystem type, choose Free (unallocated) or Whole scan scope, and set an output directory. Non-interactive mode uses /d and /cmd flags with fileopt filters to target specific file types.

Yes, PhotoRec bypasses the file system and carves files directly from raw sectors using header/footer signatures, so formatting does not prevent recovery. Use Whole scan mode on the partition and expect a higher false positive rate from fragmentation.

Carving bypasses the file system, so output files are named fNNNNNNN.ext in recup_dir folders with the recovery time as mtime. To restore names and MAC times, correlate results with $MFT, USN journal, or inode records separately.

Most deleted data on SSDs is unrecoverable after TRIM executes, since the blocks are cleared at the hardware level. PhotoRec only recovers data still resident in unallocated sectors, so overwritten or TRIM'd regions yield nothing.

PhotoRec supports 300+ formats with interactive and command-line modes and ships with TestDisk. Foremost and Scalpel are alternative carvers; Scalpel offers higher performance through multi-threading and configuration-based signatures.

Fragmented files stored in non-contiguous clusters are carved only up to the first gap, producing truncated output. Validate every carved file with file signature checks, jpeginfo -c for images, and format-specific openers before treating results as complete.
