Which CD drive is broken?

[Guest]

A CD burned on PC1 cannot be read by PC2. However, it can be read by PC3.
Common sense says that the CD drive on PC2 is broken. However, a CD burned on
PC3 can be read by both PC1 and PC2 (PC2 does not have a CD burner). Which CD
drive is broken (or what is the problem)?

Thanks,

PC1 is burning too lightly. PC3, being a burner, can read it anyway.
PC3 happens to burn darker bits. PC2, being only a reader, expects
permanent burns, and has a weaker reader, as per its minimum
requirements. PC2 is probably older too, possibly designed before CD-RW
were designed.

Thanks Elmo. Your explanation seems right except that PC2 is only about a
year or two old (in other words, after CD-RW designed).

Was packet-writing software used to burn the cd on PC1? If so, PC2 needs
to have the same packet-writing software or a UDF reader installed. If
the cd burned on PC3 is a regular cd-r burned without packet-writing
software, that's why it can be read everywhere.

It doesn't follow that any drives are necessarily broken.

PC1 used Roxio's drag-to-disc software to create the CD. I have no idea if
that uses packet writing software or not. Next time I'm over there I'll try
writing the CD from PC1 using Windows built-in burner.

If you can just drag/copy the file to disk and your file gets written then yes
that is "Packet writing"

Yes, that is packet-writing software. This is why I never recommend
backing files up to CD-RW's and using packet-writing software. Just use
plain old CD-R burning to ensure maximum compatibility between systems.
