I was using my Iomega ZipCD 8x4x32 CD-RW drive reasonably intensely, burning
seven CDs in a row. These all came out successfully, but after that I only
get errors. I had a few coasters and one where the disc wasn't fixated
correctly (I correted this by fixating it manually afterwards). After that,
all attempted burns stop before actual writing even begins (the writing light
on my drive is not lit yet). The following is output from X-CD-Roast, which
uses cdrecord:

I have tried turning my computer off and on again (leaving it off for a few
minutes in between). Simulation writes appear to work fine. I can check the
ATIP info on a newly-inserted disc with no problems, but when I try even a
simulation burn and check the ATIP info again, X-CD-Roast gives an error
saying that the disc doesn't have that info.
Could this be a problem with X-CD-Roast only, or is it something more general?
