This question is more of a general computer question than just an 8-Bit question, but since I've experienced it the most there, I thought I would ask it here.
Do CRC errors always equal damaged/corrupted/unusable data?
I've been imaging a lot of old disks I've accumulated and got a lot of CRC errors in ProSystem. The disks weren't kept very well. All the games on the disk still seem to work though, and I don't get any load errors, and everything works on the image file too. I can also write the image back to a disk without a problem.
I only vaguely understand what CRC is used for (other than the fact that it is a method of checking for errors) but it isn't clear to me if CRC errors always mean bad data.
Also, does copying/imaging disks actually copy the bad CRC properties?
