Our office has a network of 6 macs. They range from an 8500 through imac's to a G4. All are running OS9. We regularly receive CD's burned on PC's in the ISO9660 format. in the past we have had no problems at all reading these CD's. Recently though up to 60% to 70% of the CD's we receive have failed to be read! When the CD is inserted a message requesting reformatting of the disc comes up. These Cd's however do read on a PC. We tried the discs on a Powerbook running OS 8.6 and the problem is the same. I have installed the Joliet Volume Access extension and the problem persists. I have found a solution that is unsatisfactory. When the CD is placed in a burner and I then import the session the data will be loaded. I then burn a new session onto the same disc without any extra data. The cd will then be read without any problems on the MAC. While this is a solution it is not ideal with the bulk of CDs we receive. We have thought that maybe new PC software has been released which does not conform with mac standards. If anyone has any ideas could they please respond. Thank you in advance. Glyn Thomas

I'm not sure if a tiny program found on the internet will help you with this, but it helped me ... it's called ISOnoHFS-2. A search is worth the effort (I didn't note the URL when I got it ...sorry)
