I have three cd-roms to be used with a pentium-100 DOS pc.
For clarity let's name them cdrom1, cdrom2 and cdrom3.
Cdrom1 works good with all CDs.
Cdrom2 and cdrom3 were problematic, friend suggested to clean the lens, I did so, that did not solve the problem.
But I noticed that cd-rom2 fails to read Elba CD most of the time (~80%), but always reads credit card CD.
Cdrom3 almost always fails to read Elba CD (~95%), but always reads credit card CD.
What could be the problem with these cd-roms and can be fixed?
