fedora14 want to mount joliet Cd escape seq 25,2f,40
 
dont know how to do it

i have a cd that shows you an empty directory unless you mount it for the joliet extensions - specifically 25 2f 40. It uses wide characters with the high half null.

cam someone give me a suggestion?

no wonder i had to look it up

Quote:

Joliet is an extension of the ISO 9660 standard, developed by Microsoft for Windows 95,
can you mount it on windows and then re burn the cd in a std format

yes - i could do that, or merely read it from windows
i boot fedora on drive 0 and win98se on drive 1

it displays fine on win98se

i was trying to find out whether there is a way to mount it on fedora and assumed that maybe there was a mount option that would do it.

i infer from your comment that it is not exactly standard, although the author says i am the first to complain

I figured it out - its a bug in Fedora 14

The offending CD uses wide characters and long filenames. Fedora handles this with a volume descriptor of type 2, wherein the escape sequence is specified

but

the people who authored this CD did something a bit out of the ordinary. they included two type 1 volume descriptors ahead of the type 2 volume descriptor.

windows scans all the volume descriptors- spots the type 2 and sets it up for wide characters long filenames. Fedora aparently merely looks at the 2nd descrptor to see if it type 2 - however it is a repeat of the first - and decides that there is no type 2 descriptor here. thus Fedora opens it for 8 bit charactrers and 8.3 filenames

but

the authors of this CD did not include a directory or path file for 8 bit characters and 8.3 filenames - so to fedora the CD appears to be empty.

I've sent in a bug report to bugzilla.
