Slower importing all of a sudden

[bryant]

On my laptop E1505, it seems that the imports are now taking twice as long as they used to. And at about 5 to 8 songs into the process it stops and freezes up the screen. The mouse sort of moves around on its on until I ctrl-alt-del and get the task manager to close Hoster. Until I do that, I can't even get the disc out of the dvd drive. The discs inport fine out of my ext. Plextor 716U; about 18 songs in 6.5 minutes.
I even tried slowing down the speed to 8 and 6 on the internal drive, but still seems to halt and freeze up things after several songs?
What might be the cause of something like that?
