Re: [Bug-ddrescue] EOF found before end of logfile on FreeBSD 10

Your report does not make sense to me. Maybe you have mixed logfiles or 
something. The status from ddrescue says it is "Splitting failed 
blocks...", but the status from the logfile says ddrescue is trimming 
failed blocks:
  # current_pos  current_status
  0x11AF9FC00     *

It seems the logfile attached is from a previous run.

This problem has nothing to do with the destination. The problem is that 
the system is reporting End Of File in the input file in the middle of 
the file (5082 MB of 163928 MB) after 99.99% of the data beyond 5082 MB 
has already been successfully copied.

Maybe, but this problem seems more probable to be in the kernel or in 
the C library than in ddrescue. It seems as if the C library function 
"read" is returning a value of 0, meaning EOF. (See io.cc line 63).

You are welcome. :-)
