When I try to mount it, I get this error: mount: wrong fs type, bad option, bad superblock on /dev/scd0, or too many mounted file systems and in the logs: VFS: Disk change detected on device sr(11,0) attempt to access beyond end of device 0b:00: rw=0, want=688290, limit=203728 isofs_read_super: bread failed, dev=0b:00, iso_blknum=344144, block=344144 When I do the SAME mount on my IDE CD, same machine, it works, and the logs say: VFS: Disk change detected on device ide0(3,64) scanning for RockRidge behind XA attribute last message repeated 38 times and I can then access the CD-ROM. This is a picture CD-ROM burned by a shop in France (FNAC, in case there are other french readers). With VMWare running on the same machine, when I connect the IDE CD-ROM to the virtual machine, I can read the CD, but partially. Some directories are missing. So the CD-ROM is not "clean" -- I suspect the session is not closed. What troubles me is the different behaviour between the SCSI CD-ROM and the IDE one. Any explaination? Raphael
