How long does it take to retrieve data from unreadable files?
A. It depends. With anything except a UDF packet-written disc, like DirectCD and PacketCD, it takes less than a minute usually. Packet-written discs can take much longer, sometimes as long as a day, depending on the drive and the disc. The problem is not the speed of the drive, but is instead that the drive slows down to try to read sectors that are not readable – this is normal on such CD-R discs.
