Here's another odd one for the experts!
A set of 4 disks for GPS programme installation ran fine on an Adaptec 32xCDRom a year or two ago. I now have a LG4160B (firmware 304) CD/DVD do-it-all thingy - and it will not recognise the disks in W2000, XP or DOS. Disks fine in old IBM laptop, new set sent by software company still the same. Disks show in IBM as CDFS file system.
Everybody stumped! ALL other CDs/DVDs run just fine in it.??????
