I don’t have a proper home page for dares, so if you can track it down, let us know where the original is found. Until then, here’s the Linux Mint version and the Debian package page.
dares is a CD recovery tool which apparently can retrieve data even from unmountable discs. As luck would have it, I don’t have any unmountable discs, so my leftover PLOP boot disc will have to suffice.
dares needs little more than a device address (or file name, in the case of a corrupted image, which is also a potential target) and a directory to place its files before it will swing into action.
After reading the disc content, you get a straightforward menu for recovering and saving accessible data. Fairly foolproof, and fairly reminiscent of photorec or a few other data recovery tools.
Beyond that point though, I can’t really vouch for dares any more than I could for foremost or safecopy, just because I don’t have a damaged medium to test. If you do, and you’ve found your way to this page, I can only hope it does the trick for you.
Keeping this — as well as the other three I mentioned — in mind when I do stumble across a damaged drive … well, that’s the other trick. 😉
You can fetch the source code of dares from: ftp://ftp.heise.de/pub/ct/ctsi/dares.tgz. See at Debian copyright info in: http://metadata.ftp-master.debian.org/changelogs//main/d/dares/dares_0.6.5-7_copyright
That might be the closest to a home page that I have seen. I’m not sure where dares came from, but other than the Debian package page (and your link), I’m not finding anything. 😦
