Yes, the method you describe allows you to get the system to mount these disks. Unfortunately in some cases, the system still can't contend with the content correctly. If I look at the mounted disk with the Finder, things look basically OK, but as you state the file sizes are not correctly reported. If I try to copy a directory from the CD to the desktop, I get the following error "You cannot copy 'datar' to the destination because its name is the same as the name of an item on the destination, except for the case of some characters". From the terminal the directory looks like this.

Apple needs to support Joliette Level 3 file systems.

Thanks

I guess that there is support for level 3 as the CDs burnt by Finder supports or has level 3 incorporated into the hybrid CD that is created. The problem could be the strange conflict because of MS attempts to reconcile MS-DOS and Win 95 systems in the past:
http://docs.info.apple.com/article.html?artnum=20752

But all this still do not explain why we need to manually mount a level 3 CD or DirectCD created CD using this hint or the AppleScript that follows this hint. The script works wonderfully fine!

try
	tell application "Finder" to set finderDisks to name of disks
	set currentDisks to do shell script "disktool -l"
	set AppleScript's text item delimiters to return
	set currentDisks to every text item of currentDisks
	set unmountedVolLine to ""
	repeat with currentLine from 1 to the count of items in currentDisks
		if item currentLine of currentDisks does not contain "volName = ''" then
			repeat with i from 1 to the count of items in finderDisks
				if item currentLine of currentDisks contains "volName = '" & item i of finderDisks & "'" then
					exit repeat
				else
					if i = the (count of items in finderDisks) then
						set unmountedVolLine to item currentLine of currentDisks
						exit repeat
					end if
				end if
			end repeat
		end if
		if unmountedVolLine is not equal to "" then
			set AppleScript's text item delimiters to "'"
			set diskIdentifier to text item 2 of unmountedVolLine
			do shell script "mkdir /Volumes/temppccd; /System/Library/Filesystems/cd9660.fs/cd9660.util -M " & diskIdentifier & " /Volumes/temppccd; disktool -r"
			exit repeat
		end if
	end repeat
	if unmountedVolLine is equal to "" then display dialog "There are no unmounted disks." buttons "OK" default button "OK"
	set AppleScript's text item delimiters to ""
on error error_msg number error_num
	set AppleScript's text item delimiters to ""
	display dialog "Error " & error_num & ": " & error_msg buttons "OK" default button "OK"
end try

I just tried this on a CD created with a Sony digital camera, that uses the mini-cd's. OS X was never able to mount those CD's, but this hint let me have access to the pictures.

Very nice!

I tried the script (thanks!) to mount Joliet CDs created by a cardiac ultrasound unit, that stores files in DICOM format.
It mounts fine, but the files come out with some corrruption, as no DICOM viewer (e.g. Escape, or OsiriX) can open them. My current solution is to use Thomas Tempelmann's Joliet file system extension, which runs under OS9 - but, unfortunately, can't be used in Classic mode.
It would be nice if a solution that is fully OSX-compatible comes about.
Still, thanks for the efforts.

I had a neighbor bring a disc that would not mount and I thought "what about disc copy?"

The volume will show up in disc copy but won't mount. I created a new image from the volume and voila! I can mount it and see all of the contents. I didn't have any trouble with any of the content.

I then burned the image and it worked fine for me as well as for him.

GREAT! Finally I have all of my digital photo CDs I made with my PC laptop on my G5... it worked, thanks! However each of the original TIF files (Minolta Dimage7) will not open now. Somehow this method has corrupted the files and none of my photo/image/graphic software will recognise them. The smaller thumbnails of the same files (on the same CDs) open OK. Weird.
Those that I import direct from the camera I have no problem with.

(Hi from a newby who hopes this addition to an older thread doesn't go unnoticed)

Does anyone have experience with this utility (or the company)?

http://www.softarch.com/us/products/rdvd.html

I find their OS X system requirements a little suspect (a 68040 with 8Mb of RAM....)

i'm trying to get this to work but keep running into this issue- any ideas on how to work around this?
[code]
Silver:~ eric$ mkdir /Volumes/pcdisc
mkdir: /Volumes/pcdisc: File exists
Silver:~ eric$ /System/Library/Filesystems/cd9660.fs/cd9660.util -M disk2s0 /Volumes/pcdisc
mount_cd9660: Input/output error
[/code]

Hi!

I always get a Resource Busy error. Anyone could help?

Thanks!

Luc

It is quite clear that the ISO 9660 driver in OS X is not able to read fragmented files, as they may only appear in ISO 9660 Level 3 discs (but not in Level 1 and 2).

Now, if you use the above method to mount such a disc on your Mac, it only means that you can access unfragmented files. But those that are fragmented (that's the ones that appear with multiple identical names in a listing in Terminal) can not be read completely as either the OS X driver would have to know how to concatenate them into one single complete file, or would allow us to read all the pieces and put them together ourselves. Neither works, however.

Hence, if some of you report that they could read all their files, then you were just lucky that none of them were fragmented on the disk (or you haven't even noticed yet that you have some incomplete files now).

Whether you have fragmented files on a disk or not depends on the software that wrote it, and how. I'd suspect that those Sony cameras who write pictures to CD-R are able to write the picture files in one piece (unfragmented) to the disc, so you'll be able to read those pictures just fine with the methods described here. But if you've used DirectCD on Windows, it's more likely that large files that you copied to the CD-R are fragmented, as that's how DCD works when it writes large chunks of data - it can't write them contiguously, or so I believe.

I hope this clears up the effects people have seen here.

Basically, if you have a Level 3 disc that you can only access with the methods described here, better make sure that when you copy the files off of the CD, that they're really all complete. If you have incomplete files or other read problems, you need to use a Windows system or Mac OS 9 with my Joliet driver (www.tempel.org/joliet/) to read them properly.
