This is the command ecm-compress that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
ecm-compress - selectively strips error correction codes from CD images
SYNOPSIS
ecm-compress cdimagefile [ecmfile]
DESCRIPTION
ecm-compress reduces the size of a CD image file (ISO, BIN, CDI, NRG, CCD or any other
format that uses raw sectors) by eliminating the Error Correction Codes (EEC) and Error
Detection Codes (EDC) from each sector when possible.
Since the data ecm-compress strips is usually nearly impossible to compress with
traditional tools, the resulting ECM file will compress far better than the raw CD image.
Hard drives already have mechanisms to protect data integrity, EEC/EDC data can thus be
discarded safely.
This data can then be generated again using the command ecm-uncompress.
Because ecm-compress only discards EDC/ECC data for sectors where it's verifiably possible
to recreate that data, the process is lossless. In case of copy protection, ecm-compress
will preserve the bogus data.
EXAMPLES
ecm-compress foo.bin
strips the ECC/EDC data from the foo.bin CD image and save the resulting file as
foo.bin.ecm
ecm-compress foo.img foobar
strips the ECC/EDC data from the foo.img CD image and save the resulting file as
foobar
