...are there more than one ddrescue apps?
I think there are 3:
Ddrescue, Dd_rescue, gnu_ddrescue are 3 different packages iirc. The names of the executables overlap iirc, so it is easy to get confused so I only install one at a time.
Gnu_ddrescue has the functionality of Dd_rhelp integrated in. If you don't know any of them, you might as well use the gnu version since it is more sophisticated.
On 13.1, found and installed: dd_rescue-1.40-2.1.2.i586 dd_rhelp-0.3.0-7.1.2.noarch gnu_ddrescue-1.17-2.1.2.i586 man ddrescue produced man page for 1.17, so that's what I tried first after not actually understanding dd_rhelp's description of the last input option about info. The 1.17 page had so many options for telling it how to do its job I missed -v. :-( Of the three source files, two result files played without apparent flaws. One "played" nothing but silent black for several minutes before I gave up trying. Mc F3 viewing the black file I see from front well into the file nothing but nulls, binary stuff in its tail. Logs from the first three done with 1.17: OK http://fm.no-ip.com/Tmp/Linux/bbt0512-201312181730.log bad http://fm.no-ip.com/Tmp/Linux/closer0710-201312190130R1.log OK http://fm.no-ip.com/Tmp/Linux/closer0720-201304040230.log Looking at those logs it wasn't clear to me what they were saying, whether those numbers represent bits, bytes or sectors, and whether relative to file start and end, or filesystem addressing, until finding the man page discussion of them. I retried the one that failed with dd_rhelp, but it produced only 15%-20% of the total before it quit trying. What the log doesn't indicate is it actually ended with a segfault: http://fm.no-ip.com/Tmp/Linux/closer0710GDMX09-201312190130.ts.log I retried same one again with 1.17: http://fm.no-ip.com/Tmp/Linux/closer0710-201312190130R2.log This too played without apparent flaws, so now that my backup HD is in the STB I need to focus on finding a new backup and doing another rsync so that I actually have a backup to count on. -- "The wise are known for their understanding, and pleasant words are persuasive."
