sysutils/ddrescue helped me to read broken drives several times, it retries then skips on errors. sysutils/e2fsprogs has program badblocks that can help disk rebuild in read only mode, or make things worse depending how its broken, and you can use it many loops of destructive write test to overwrite data. the safest way to dispose sensitive data is by physical destruction :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
