I have just removed the shrink-wrap from a CMC Magnetics Corp CD-RW, branded as Lite-On, that was shipped with the LTR-40125S. I brought it into work, put it in a Pioneer DVR-A03 DVD/CD writer, fired up Nero 18.104.22.168 and tried to burn to it, only to be told that it was not writable. Took the disk out and replaced it with a Mitsibishi Chem. CD-RW, branded Sony, and wrote to it fine.
Confused I took the CMC Magnetics blank and put it in a Samsung SN308B DVD-CD-RW combo drive and wrote to it fine with EZ CD 4 [don't ask!], could read it in the Pioneer DVR-A03 but still could not write to it.
I ran CDIdentifier to check the ATIP. CDRId said it had a max write speed of 8x, the branding said 12x. I checked with Nero InfoTool which gave it a write speed of 10x.
So which is correct?
