Apparently the drive has to cache audio data, which is rare. Almost all of them cache *data*, very few of them cache *audio data*. There is a control for this on EAC. I was never too concerned about this because I did get re-reads as well as synch/read errors. If my drive was caching and EAC read from the cache, there would never be a re-read. I asked the question because I'm moving to Linux and using Rubyripper which relies solely on the re-read technique. There's no control for drive caching with Rubyripper, but it is obvious my drive isn't caching, because on damaged discs, Rubyripper is reporting erroneous chunks and having to re-read the track 3+ times. > I was aminly saying that you are pretty much guaranteed to have a good > rip if AccurateRip says it's good.

Yes, I'm giving that up. It's too bad but I rip a fair amount of discs that aren't in the AccurateRip database anyway. > I do agree with you that if data is being compromised by a scratch in > the disc and that the drive is actually re-reading that data it would > likely vary. I came up with an analogy last night. Put a 20' X 20' tarp on a field of grass. Assuming you work for the government ;-) your job is to count the blades of grass in the field - at night, using a flashlight! When you come to the tarp, you have to count around it. Will your count of the blades around the tarp be exactly the same each time? No way, given the size of a blade of grass versus the size of the tarp. You'll be off by at least one. The odds you'll get it right down to the last blade of grass are exceedingly low. If you're good, you'll be close...but not perfect. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=34232 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
