Re: [Bug-ddrescue] Error in ddrescue Logfile

[Sven Achtelik]

Burkart,

the lof file was written by ddrescue. ddrescue died with the message that the 
input file is unavailable. The Disk I'm trying to rescue is connected via USB 
and stop responding. 

Thank you for your input, I'll try to fix the log file and get everything to 
work.

Regards, 

Sven

Hi Sven and Antonio!

Additionally 0x3F5680400 + 0x0000FE00 from the line above the one with
the question mark equals 0x3F5690200 which is greater than 0x3F5620000
by 0x00070200. Therefore the line

  0x3F5620000  0x0011F600  ?

should rather be

  0x3F5690200  0x010AF400  ?

where 0x3F673F600 - 0x3F5690200 = 0x010AF400.

Did you manually tinker with the log file? I've never had ddrescue alone
create an erroneous log file. Regardless of how it came about,
personally I wouldn't put too much faith in the rescued data if the log
file was corrupted and I didn't know why.

Bye, Burkart
