dd_rescue - a block copier, which ignores errors

A block copier, which ignores errors

dd_rescue copies data from one file or block device to another. It is intended for error recovery, so, by default, it doesn't abort on errors, and doesn't truncate the output file. It uses large block sizes to quicken the copying, but falls back to small blocks upon encountering errors. It produces reports that allow you to keep track of bad blocks.

Like dd, dd_rescue does copy data from one file or block device to another. You can specify file positions (called seek and Skip in dd). There are several differences:

dd_rescue does not provide character conversions.
The command syntax is different. Call dd_rescue -h.
dd_rescue does not truncate the output file (unless asked to).
You can tell dd_rescue to start from the end of a file and move backwards.
dd_rescue does not abort on errors on the input file, unless you specify a maximum
error number. Then dd_rescue will abort when this number is reached.
It uses two block sizes, a large (soft) block size and a small (hard) block size. In case of errors, the size falls back to the small one and is promoted again after a while without errors.
It does not (yet) support non-seekable in- or output.

Epiphany: Epiphany 2.20.2 out

It’s been way too long since an “official” Epiphany blog. Anyway, here are a few highlights to keep you up to date.

As Wouter noted already, Epiphany 2.20.2 is out. We even have a proper NEWS file this time! It includes a few notable bug fixes, for example in the areas of printing and session recovery.

On the GNOME 2.21 side of things it has been a bit quiet, but rest assured that work is continuing. A lot of refactoring work is taking place to bring the Gecko and Webkit back-ends on equal footing.

But even though Epiphany is “ awesome“, please keep in mind there are still lots of open bugs in bugzilla, so anybody who wants to help out, come on, don’t be shy!
