Interestingly, the clear side can take quite a scratch before it gets really bad since they will tend to be out of focus to the laser because the pits are much closer to the label side. So a less deep scratch on the label could actually cause a lot of damage. I also have a couple of disc that are old and have oxidised slightly making them unreadable - I guess that's the fate of all our CDs... cliveb;175624 Wrote: > > *All* CDs require C1 corrections, typically on every sector.

I thought it had concealment via the drive electronics, but you could be right and it does nothing. In that case, EAC would be creating audibly broken rips on bad discs rather than a barely-audible concealment.
