I've found ddreccueview an awesome add-on to ddrescue!. I do have a couple of suggestions... I'm using 0.4 alpha 3 on a standard ubuntu 22.04 install. 1) The text (I assume this is the ubuntu system default) is too big for the areas it is supposed to fit into - for example (screenshot), the letters with descenders (eg: p,g) in the main 'Rescue Status' window are chopped (eg: the "g" in 'Pending' has become an "a"). 2) Related to the above, the 'Block Inspector' "Block" id number can only fit four...

@Anonymous: Another interesting program to check out for rescue of optical discs (CD/DVD - probably Bluray) is DVDisaster. I've used it and found it quite good. I've also used ddrescue and dd_rescue before, but only for flash drives. Last week I started recovery on a damaged hard drive and stumbled upon ddrecueview - a most excellent program! I agree with Mbit that trying to set a visualisation of the sectors as they appear physically would probably be an impossible task - as far as I'm aware, that...

MBit posted a comment on discussion General Discussion
Physical layout of the logical 2048 Byte sectors on optical media would be too complicated. It would require precise information about the data track's starting diameter, track density, recording mode, and could be further complicated by multi-session and mixed mode. From what I read, most of these parameters vary even among bog-standard CDROMs. Afaik, none of this information is contained in the block-device view Linux has on the disk. While it may (?) be possible to extract this information using...

I'm currently recovering my old CDROM media. I came across an interesting error pattern. The disc has no visual defects or scratches, so it would be nice to have a circular layout, to see the distribution on the actual disc.

Hello Sean, persistent settings have been on my to-do list for very long (too long). I'm implementing something right now. Might take a few more days, I want to do it right and in the most compatible way. Greetings, Martin

@wgh @leon5x I have just released ddrescueview 0.4.5 which fixes the issue. As WGH suggested the program now simply re-opens the mapfile everytime it needs to be read. Actually I don't keep an open file handle now at all, the mapfile is being closed right after reading it. I figured that on Windows, ddrescue might get problems renaming the mapfile to .bak, unlike Linux, Windows does not allow this for files which are in use. Then again, who uses the Cygwin version of ddrescue... ;-)

Thank you for making and maintaining ddrescueview, it's been greatly useful for me. I can confirm that the Linux i386 version is working on Debian 10 Buster, and you may add the attached screenshot of it clearly working to the Project Samples page on Sourceforge, and to the list of distributions the program has been successfully run on @ https://sourceforge.net/projects/ddrescueview/files/Test%20builds/v0.4%20alpha%204/ . Again, thank you. :)

Hello MBit, That was a really good answer. It even explains some discontinuities I saw in the pattern of the failing disk. Those could have been those defects you mention. Of course, benchmarking a failing disk is not the best idea. ddrescue goes to great lengths to minimize the amount of readings from failing sectors prior to saving all the easily recoverable data. Have a nice day!

Hello, while the idea of a circular block grid is tempting, I doubt its feasibility for modern-day hard drives. These drives do not have a physical sector layout according to the CHS model. They employ many features that cause them to deviate from this "ideal" text-book layout, most notably zoned-bit-recording, track skew, and custom track layout that cannot be easily determined. Add in defect management which excludes whole regions of the platter from containing logical sectors. All this is done...

Hi, First of all, I want to say THANK YOU for this tool. It let us visualize the otherwise human-unfriendly mapfiles. Last time I used ddrescue was on a disk with a non-functional platter/head. It was evident looking at the pattern ddrescueview was showing. However, it would have been even more evident, without much use of fine zoom control, if the block grid was instead a circular layout. I guess that it would require entering C/H/S info in order to render an accurate layout (or at least a render),...

Googling the error message took me to https://wiki.freepascal.org/User_Changes_Trunk which has an entry "Property field access lists no longer allows classes" that seems to describe the problem. Poking around in svn it seems that this change was backported to 3.2 but they forgot to move the description of it from the "user changes trunk" to the "user changes 3.2" page. The solution is to use a getter rather than direct access for the property. I have attatched a patch that does that, I have tested...

Hi & thanks for ddrescueview! I wanted to share my experience compiling ddrescueview 0.4 alpha 3 on MacOS 10.14 (Mojave - currently the most recent version), in the hope that it'll be helpful for anyone else who wants to do the same. In short it was pretty easy, with only 1 or two snags that were simple to resolve. Steps: Install Apple's Xcode from the Mac App Store From the MacOS Terminal, run "xcode-select --install" to install Xcode Command-Line tools (this is required by FPC - the FreePascal...

Thanks for the great tool, and an excuse for me to finally play with Lazarus! I recovered some of my failing disk without a domain map, then when I learned about ddru_ntfsbitmap, I used it to create a domain map and resumed running ddrescue with the domain map. I know that in my first run of ddrescue, it recovered a lot of empty parts of the disk. When I tell ddrescueview to open the domain map, if I understand correctly it shows "Not in domain" for any area that isn't in the domain, even if the...

Hi, mbit! I find ddrescueview pretty amazing. Have been using it for some time now to inspect and live preview of my data-rescue jobs. Have some suggestions for improvements (unfortunately Pascal is pretty remote for me so can't propose sample implementation) Track active block in the main view (could be an option in view menu, or take precedence form block navigator check box) RMB select in zoom bar (would be very useful to un zoom to specific area, instead of using mouse wheel) Mouse wheel zoom...

Logfile format changed since ddrescue 1.22

Dear olegkrutov, ddrescueview version 0.4 alpha 3 contains a fix for this change in logfile format. You can find it under the 'Test builds' folder in the download section. Don't be afraid by the fact it says 'alpha', it's been used almost for a year now with no bug reports and can be considered the current 'stable' version.
