Is there an ISO 9660 filesystem on the CD, at all ?
What do you get from
file -s /dev/cdrom
--------------------------------------------------------------
The message can come from two sources: genisoimage/scsi.c and
genisoimage/multi.c. The latter would be not plausible.
A look into genisoimage/scsi.c tells that the program tries to
move the file read pointer to the start of a data block.
Probably called by genisoimage/diag/isoinfo.c line 933:
readsecs(16 + toc_offset, &ipd, ISO_BLOCKS(sizeof (ipd)));
The variable toc_offset is supposed to be 0.
(Not understanding what's underneath getallargs(), i assume
from the man page, that option -T would set a non-zero value.)
Any ISO image is supposed to have a Primary Volume Descriptor
block at address 16.
Thus my question, whether it is an ISO 9660 filesystem.
Have a nice day :)
