Re: Overburned DVD data recovery

I also tried running cat /dev/acd0 | gzip data.iso.gz in an attempt to grab the raw bits of the disk, but that only resulted in an input/output error. You could try readcd and isoinfo (/usr/ports/sysutils/cdrtools-devel) but those few hundred megabytes at the end will still be lost.
