Re: Problem reading Windows CDR
I dont know if this is it but ive plaed with DirectCD, it does NOT write to the cd normally, it creates a file with its own type of file system :-/ if u put in in a windows box u will see it will install the files needed to read from it...

Just to make sure you're talking of *CD-Recordables* here and not _CD-Rewritables_? I myself I've never seen or heard of such problems with CD-Recordables. On the other hand I've experienced and heard often of all the above problems in relation with _CD-Rewritables_ . -- groetjes, carel

It's actually "UDF", not "UFS". There is experimental support in the kernel for reading drives like this. There's also a site on sourceforge.net, who's name escapes me at the moment, with more information on this. You are correct about telling DirectCD to make the CD readable by other drives... if you don't do that, many non-Windows users will have trouble with the disc. I have Easy CD Creator and it installed DirectCD, but I quickly removed it. Regards Hall

CDFS = UDF afaik, the 2.4 kernel has read-only support for UDF, so i don't think it's very close to iso9660. i suggest burning the CD with some other windows burning program, like easy cd creater, nero or winoncd -- ,---. > Name: Alson van der Meulen < > Personal: [EMAIL PROTECTED] < > School: [EMAIL PROTECTED]< `---' Well, my files were backed up. -

NOTE: Unless directed to "Make CD readable by most other CD-ROMs" or some such, DirectCD writes using "CDFS" and doesn't write some other necessary info for ISO9660/Joliet conformance. If I understand correctly, this "CDFS" is UFS?? This may not be the problem, since I wonder how Linux could mount the CD without the newer filesystem support (maybe it looks close enough to iso9660 to fool the kernel?). It's worth investigating though... I know for a fact, if you don't do this with DirectCD, older Windows machines will not be able to read these CD's (not to mention Mac's). -- Eric G. Miller

Well, as it happens, the CDR that works (the Debian one) and the CDRs that don't (the MP3 M$ formatted ones) are the same dye type -- in fact, they are from the same box. Also, the fact that I can get varying amounts of data off the CD seems to further discredit this theory. Why should I be able to read some of it, and not other parts?

I used to have problems reading some (not all) CD-Rs with my old 2x cdrom. The problem was just that the drive was not designed to read those CDs -- it was just too old. I suspect that the varying amounts of success I had (ie some CDRs worked, others didn't) was due to the dye types used in the different CDRs. I never worked out which dyes were better than others. Now I have a cdrom that reads everything (including CDRWs) so there's no problem.
Problem reading Windows CDR
Hi folks. I have a rather large collection of MP3s that I burned onto CDs using my step-brother's burner, which is on a Windows box. I burned it on using the DirectCD system. Anyway, I compiled Joliet extension support into my kernel and can mount the CDs fine; I get a directory listing, and all seems to work okay. However, I was unable to play the MP3s off the CD -- I presumed this was because I have an old computer whose CD read speed was simply too slow. So I decided to copy the file onto my drive. Upon doing so, cp hangs for a long time as the CD sounds like it's 'trying' to read. Eventually, I get "cp: reading 'Foo - Bar.mp3': Input/output error" on stderr. However, the cp was partially successful: a portion of the file does seem to transfer. I know this isn't a problem with my drive because my Debian CD, which I burned on the same CD burner (albeit without the DirectCD stuff) reads quite correctly, even with large files (like tetex-base). Of course, that's ISO9660 + rockridge instead of joliet extensions. I can get small text files and such off of the CD. The partially cp'd mp3 is not corrupted in any way, it's just not complete. I know it isn't the CD, because I can read them properly with my roomate's Windows computer. So basically, I'm at a loss. Has anyone had similar problems? I have an ATAPI compat cd-rom drive, am running linux 2.4.2, Debian/testing. This problem occured also when my box was stable with a 2.2.17 kernel. This is a CDR, not a CDRW, btw. Thanks for any help you can give. I'm at a loss w/o my music! -- Alexander Poquet| We leave the obvious generalizations to the [EMAIL PROTECTED]| reader. -- Israel Herstein Use of PGP preferable in reply | Use Linux! pgpaRTkw0wrqS.pgp Description: PGP signature
