I have two machines, a new IBM Thinkpad with a Matshita CD-RW and an old 333 Gateway with a Matsumi CD-Rom using a 1999 MS Driver. The 1999 CD-ROM will not read diskS created by the CD-RW. I'm using standard Imiation CD-R disks. Is age the factor here? Software (I use both XP PRO copy and the simple RecordNow utility that came with the IBM). Thanks.
