  1. Re:Same problem with CD-RWs by Col.+Klink+(retired) · · Score: 1 · on Fatal WeaknessWith High-Capacity MMC/SD Cards?
    DirectCD doesn't use a proprietary format, it uses the UDF filesystem and packet writing. The 2.4 kernel has read support for such drives, but not write support on CD-R drives due to lack of kernel write support for CDR/CDRWs. For more info.

    You need to have the DirectCD software installed on windows to read it because it's not supported in the kernel before WinXP. When you use DirectCD to format a disk, it creates a minimal ISO9660 filesystem with the DirectCD-reading software.

    I wasn't able to use the UDF filesystem on older CD-ROM hardware, but it should work fine on all the CD-R and DVD-ROM drives.

  2. Re:UDF by The+Bungi · · Score: 1 · on Dell Dropping The Floppy
    As far as I know, Windows ME and lower don't support UDF without the Adaptec driver. Windows 2000 supports reading from UDF volumes but not writing (again, you need DirectCD), and I believe XP supports reading/writing to them because it has burner software built-in.

    Linux support seems to be there, albeit in read-only mode as well.

    I don't know if the UDF spec is owned by Adaptec - maybe it's time for a new industry-wide standard.

  3. Linux DOES have UDF support! by BLiP2 · · Score: 1 · on Jon Johansen's Answers to Your DeCSS Questions

    just as a side note, he said that they choose to use windows because it had support for UDF. I found a great little kernal module for reading UDF the other day when I wanted access a DirectCD disc I had (also UDF).

  4. UDF support in 2.3.17 (read only) by geirt · · Score: 2 · on DVD for Linux: an Interview With the Developers

    Subject: UDF filesystem patch for 2.2.12

    Date: Mon, 20 Sep 1999 02:08:43 GMT

    I've made a new UDF filesystem patch for kernel 2.2.12. You can get it at: http://trylinux.com/projects/udf /udf-latest.tar.gz (about 70k)

    The module has been tested by a diverse group for some months now, with no reports of meltdowns, so it's probably safe to include in the 2.2 source tree. It was included in the 2.3 tree in version 2.3.17.

    I can say from observation that UDF use, in the form of DirectCD written CDRs, has become very widespread across businesses. Having at least read-only support in the Linux kernel would be a definite plus.

    Unfortunately, write support will have to wait, as the write support in this driver doesn't work with CDR/CDRWs yet.

    Looks like UDF will be supported in 2.4.

  5. Write support by dboynton · · Score: 1 · on CDRW UDF Filesystems for Linux?
    The read support in UDF is coming along nicely, thanks to Ben Fennema. Ben is working on the write support, but progress is hampered by lack of support in the IDE and SCSI CDROM drivers. They have no write (or DVD) support at all. That leaves us with the very ugly choice of going direct to the hardware from within a filesystem driver.

    If anyone wants to help out with this project, what I think we need the most right now is someone to work on patches for the IDE & SCSI drivers to support the SCSI3/MMC command set. Please visit my TryLinux site and join the mailing list if you're interested.

  6. More UDF links by Anonymous Coward · · Score: 0 · on CDRW UDF Filesystems for Linux?
    UDF is still in pretty early stages of development.

    Ben Fennema seems to be most active developer at the moment. The current UDF driver only supports reading, but work is beginning on writing. TryLinux has a project page for UDF, which includes links to the specs.

    There is also a mailing list (for developers, pretty low-volume) here. Send 'subscribe linux_udf' in the body of the message.

  7. SORRY. Only SOME DVD support for Linux by deathcubek · · Score: 1 · on Ask Slashdot: Audio/Video Networking Solutions for Linux?

    is that most decoder cards don't have drivers
    Right, some hardware vendors are being a cry babies (wah!!! you have to sign a NDA wah!!!)

    UDF isn't yet supported.
    Well, it's getting there and is not that important right now

    what's exciting is that some DVDs seem to be able to be played
