Some CDs have their directory sector entries exceed the sector, and AFAIK the problem is that they exceed it not entry by entry, but in the middle of a directory entry, which violates the ISO9660 spec. The Linux CD-ROM driver used to have a workaround for this, but then after 2.0.x it seems to have been removed. Why ??? After all Windows perfectly accepts these broken (ISO9660 wise) CD-ROMs. I don't know whether 2.4.x still has the same "feature" that 2.2.x had. A Spanish language training CD of mine has this problem, and I can't read several files on it. Hmm, or maybe your problem is simply that you forgot to enable the "hidden" mount option for your CD-ROM ?? (some files are burnt with "hidden" attribute !) Andreas Mohr
