Error correction for Apple Lossless?

Jeffatus, you're probably talking about Itunes option. Set it ON - it will slow down ripping (slightly) but will prevent pops. Better yet, download better ripping programs (like EAC for PC or MAX for Mac - both free). These programs can be more accurate than Itunes but difference would likely be detectable only on scratched CDs. These programs will go many times to the same sector until proper checksum is obtained (I set MAX to do it infinitely) while Itunes seems to give up and interpolate after fewer attempts.

Thanks for the reply. Since I have already ripped 80% of my CD's, would you go back and redo all of them or do you think I can just re-rip the CD's I can hear issues with?

You can always rip one CD again with new settings and compare. If you don't hear improvement then leave it alone (unless you have pops and clicks).
