Extracting from CD: bad pregap on CD causes never-ending re-reads

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Find a CD with bad pre-gap (some defect that makes reads bad?)
2. Either let xld do its initial pre-gap scan, or turn that off in the 
preferences and simply include pregap in the extraction process

How about the reproducibility (always, sometimes, rarely, ...)?
Just on this CD that has a pregap problem apparently

What is the expected output? What do you see instead?
I expect a problem reading the pregap BUT eventually it should stop trying.  
Instead this never stops trying to read the problematic pregap.  The drive just 
keeps thrashing and thrashing for minutes until I force the program to quit (by 
right-clicking on icon and selecting Quit, I don't actually have to "Force 
Quit".)  It is stuck on one particular track and the progress meter is at 0% 
(no length of progress bar on that track.)  Other tracks extracted ok up until 
that point.

What version of the product are you using? On what operating system?
XLD Version 20140504 (147.0)
Mac OS X 10.9.5
Please provide any additional information below.

If I allow the default preference: UNCHECKED "Don't detect pregap, ISRC and 
MCN" then it will endlessly thrash during initial pregap scan.

If I CHECK "Don't detect pregap, ISRC and MCN", then it will endlessly thrash 
during the particular track that has a problem.

I have a Mac Mini, Optiarc DVD RW AD-5670S, Firmware 2AHI

Actually this may not be restricted to xld.
I just tried to do a file copy in the finder of the track that was giving 
problems, and the drive started thrashing without any involvement of xld.

So it may just be a disc that my drive can't handle.
