Maybe it is a problem that has nothing to do with the quality of
Here's my own experience ...
I was having all kinds of trouble with bad disks. The procedure
seemed to work fine, but the disks had errors. There were a
few (about 3 on average) corrupted files on most disks.
I had a cheap drive, and thought that was the problem, so I
bought a new one. I was told that Plextor was the best, so
that's what I got. It still had errors, about the same as
I use mkisofs and cdrecord. After getting a bad one, I tried
again from the same image file. Same errors. Check the file.
It's bad too. (CD-RW, of course, for the experiments)
It turns out the problem was the VIA DMA bug. It worked with
DMA disabled, but a large partition with ext3 was now too slow
to burn a CD at 4x. (Reiser on the same size partition was ok
at 12x, with DMA off.)
Fortunately, my motherboard also has a Promise controller on it.
Use that instead, problem solved. No more coasters.
