A few fixes and a possible enhancement to the ddrescue filter. If you think these are all OK, I will squash it into your patch and push it. Rich.

This allows to overlay bad sectors according to the mapfile generated by ddrescue, to then see where sectors are used using fsck and trying to copy files around. Should now be mature enough to be useful to someone else. And we have a proper test also. Signed-off-by: François Revol <revol@free.fr> --- configure.ac | 2 + filters/ddrescue/Makefile.am

I'm pleased to announce the release of nbdkit 1.22, a high performance plugin-based Network Block Device (NBD) server. https://en.wikipedia.org/wiki/Network_block_device Key features of nbdkit: * Multithreaded NBD server written in C with good performance. * Minimal dependencies for the basic server. * Liberal license (BSD) allows nbdkit to be linked to proprietary libraries or

I have a full disk image file (courtesy of ddrescue), and need to mount one of its partitions. I suppose I should have just extracted the single partition when I was using ddrescue, but right now I have the whole disk instead, and no disk space left to re-do the extraction (in fact I won't be able to use the system where I did it for several weeks, so I'd love to be able to mount just the

Well, I'm not a noted expert on ddrescue, but my limited experience tells me that when it hits bad spots (or a big cluster of them) it can go very slowly as it tries multiple times to read each sector (or track, I'm not sure which, in this case). It keeps a list of bad spots and goes back at the end to try again to read something from them. Of course, if you've had, eg. a head crash,

I have a disk that is flagging errors, attempting to rescue the data. I tried dd first - if gets about 117G of 320G disk and stops incrementing the save image any more. Now I'm trying ddrescue and it also stops about the same point Thoughts on how to continue past that point ? Thanks, Jerry
