狗爺語錄

Some of the photos were secretly deleted from my digital camera by a certain guy few weeks ago. Surely, with valid reason, he didn’t like some of my photos. Though I have backup of some of them, other newer photos are not backed up, thus only data recovery can come to my rescue. As a Ubuntu partition is available, I decided to gives the tools mentioned in Ubuntu Data Discovery wiki page some testing, all of which are readily installable with apt-get.

My test points to the following conclusion:

scalpel is utterly useless when discovering digital photos, while other 4 tools (foremost, photorec, magicrescue, recoverjpeg) achieve similar degree of recovery, with photorec edging out the other 3.

Though there was an existing test between scalpel and foremost, it only compares their speed, but gives no comment on whether software works or not. Data discovery software must try to discover as much evidence as possible, speed is just marketing gimmick when tools don’t work at all.
