Wel, I can read my Mavica-formatted CD-Rs using Joliet Volume Access
extension in Mac OS 9.


Joliet is an (originally) MS-proprietary enhancement of ISO-9660. 
Nothing to do with UDF.

Various versions of UDF used in the market:
* V1.0.2 - Basic file system used by DVD-Video discs
* V1.5   - Support for CD-R and CD-RW drives and media
* V2.0   - Support for NT streaming
* V2.0.1 - Support for Video Recording (VOR) Files

In the classic Mac OS, Apple supported UDF 
1.0.2 with their "UDF Volume Access" extension. 
Adaptec enhanced this with their free "Adaptec 
UDF Volume Access" extension, which fully 
supports UDF 1.5.  Many full burning packages 
included support for UDF 2.


The udf support i have, in os 9.2.2 (it should 
be there, cause its a basic, regular install + 
that turing all ext off still wont read those, 
NOR mac os ext.


Have you installed Adaptec UDF Volume Access?


Strange that, UDF is supposedly the format for DVDs, right?


UDF 1.0.2

But when you burn discs, you're actually writing UDF 1.5

And, yeah, a friends PC w/ a burner got most of 
my files out. But all app-files were lost case. 
Obviously...
And weird that my machine virtually spits them 
out. And I thought that Mac as the underdog 
could read anything. Guess I will have to 
rethink that opinion...


This has been my experience also.

I have CDs that I burned a year or two ago -- 
some are now totally or partially unreadable in 
both my PM 7300 and B&W - 4 differerent drives. 
They're fully recoverable when read on a PC.

Makes me wonder if my G3 Gossamers' difficulties in reading  
anyhing but pure mac OS std-cd's could be something of the same?


Dirt is a possibility, but there are also basic UDF support issues  
(below).


All my other elderly macs read UDFs & MacOS ext w/o problems. I  
have to use my external burner to read my own UDFs (a disk format  
that my brand new G4 powerbook cannot read either!!!), thus I am  
slowly recopying the UDFs to MacOS std.
