Suspend your chaulk. I think there is determinism at work here. I've been
told by sales associates (snickering, like they would know anything) at
retail outlets that el-cheapo CD are good for music. For data, I was told,
you better buy a name brand el-expensivo product (smirk; more expensive is
good for the store, not me). In music and video, loss of bits and bytes is
accounted for and tolerated in the DSP in the D to A direction. (Who's going
to notice Bruce Willis had a 10ms blemish on his forehead from flipped bits
in an action scene?) In data apps there is 0% margin of error. I don't know
the ISO9660 protocol, but if there are checksums on datablocks, that could be
the reason you are getting coasters from your roaster - bad CRC on read
verify, or just plain old failed bit-by-bit failure on verify. Your
experience corresponds with the sales associates' recommendation. How 'bout
that? Personally, I chickened out and bought the more expensive CDs, so I
didn't test the hypothesis above.
