You said this:
If this disc was a multi-session disc then it might not be readable anywhere but the drive it was burned in.
You would need to finalise the multi-session disc in the drive that originally wrote to the disc in order to get it to work with one of your other drives.
But it isn’t generally true that you have to close multi-session CD-R media in the drive that burned the previous sessions. It might be true in specific cases, although I haven’t come across such a case myself.
So there’s no reason to use the “rolleyes” smiley at the original poster.
If you use UDF packet-writing software however, then it’s generally required to close/finalize the disc before it can be read in other computers.
@mikej3131: The computer that you used to create the CD, was it running Drag-to-disc, DirectCD, DLA or some other drag-and-drop software of the packet-writing type? If the answer is “yes”, you might have to either close/finalize the disc in a computer where the same software is already installed, or if you have the software available then install in on your current computer.
I don’t think the FreeWare version will read UDF packet-written discs, but it’s possible that the shareware version of IsoBuster can read such discs, although I haven’t tried this personally.
