Error correction

What does turning on error correction while ripping CD's in Apple Lossless format? It says it will slow down ripping so I have it turned off, but is it worthwhile to have this on?
Thanks for any help.
From everything I've read, if you want the most accurate transfer of your CDs, you should definitely keep the "error correction" on. In my experience, there is insignificant additional time added to the import process.
