Cyclic Redundancy Check

These have become the words of death for me.  What does it mean, and how can I avoid it?  When I burn large files, they're USUALLY ok, but if I burn a DVD full of many small files (say, roms or mp3's) it's almost GUARANTEED I will get the good ol' Cyclic Redundancy Check on at least some of them.  I took this to mean that some of the DVD's were corrupted during burning or something, but they all verified ok--what's the deal?

I'm using Nero 7 with a Sony DVD-RW drive.

a Cyclic Redundancy Check (CRC) is just a fancy checksum commonly used when transmitting data.  if it fails, that means something screwed up in your data transmission, and the data recieved isn't the same as the data sent.  the cause of a CRC failure can be pretty much anything (bad/insufficient memory, loose cord, bad/cheap disc, or drive failure are common causes).

try shutting down as many background programs as you can, and burning at a lower speed.

Also, try not using shitty DVD-Rs. Use Taiyo Yuden DVD+Rs.
