The problem you are observing is a media error: There is some spot on
your MD medium that can not be read correctly. If you play it on the
minidisc player, playback is also affected by it, but the minidisc
player does every possible work to cover up the missing data.
For technical reasons, the computer interface QHiMDTransfer uses is not
prepared to delive "approximate data", but only completely correct data
or no data, so at the spot where the completely correct data is not
available, the Hi-MD unit returns no data insted.
You are in fact the second person within a month that trips over the
error handling in libhimd/QHiMDTransfer: Currently, read errors are
unrecoverable, and continuing track transfer after a read error is not
implemented. This is something we have to fix in our software to make at
least the correctly readable parts of your disk transferrable.
As a work-around, you can try to copy the whole HMDHIFI directory using
a tool that does not abort on read errors to your hard drive, and run
QHiMDTransfer on the hard drive copy to extract the tracks from it.
Make sure that the copy tool does not just "cut away" unreadable parts,
but fills it with dummy data instead.
