Re: cdrdao extremely slow

[Peter Golis]

Hello Gentleman,
There can be also second reason, but with really low probability. Not all of CD devices was capable to transfer audio using digital line, e.g. ATA devices from dark age era. How was full output of grabbing of that CD, and how was identified that CD device (cdrdao scanbus)?
 
Peter.

I do not have recent experience with this sort of thing.

What comes quickly to my mind, is the possibility that the software is 
getting many read-errors in trying to copy the track.  But I would think 
it would give-up the attempt, reporting 'too many errors', rather than 
taking over an hour to copy it.

The second thing that comes to mind, is that copy-protection/encryption 
is causing the software to loop through a very many dead-ends.

I have never used cdrdao, so what I have offered here is pure speculation.
