At work we have the Panasonic 101 & 103 DVD-RAMs (which can read CDs, DVDs, PDs & DVD-RAMs). We also work with NT. Under 2.2.14 (and before) the DVD-RAM showed up as device sdb. This allowed us to read PD disks (650MB MO disks) which were formated under NT as either "Super floppy" or (I think) FAT disks. However there was a problem when using the DVD-RAM with an ext2 filesystem as it did not recognise that there was a media change, which ended with a reformat of the DVD-RAM disk being required unless the cache was fluhed. With the removal of the GHOST list, the DVD-RAM now shows up as sr0 (which makes more sense). However, we now cannot write to a "super floppy" PD disk without trashing the disk. Reading seems to be OK, as does creating zero length files, but creating anything bigger means that the disk cannot be accessed under NT nor mounted again under Linux. Also we can't mount FAT formatted PD disks as the sr devices don't support partitions (but doing an fdisk to find where the partition starts and then a dd to copy it to disk and mounting that image through the loopback device works....but isn't ideal...). But the good news is that we can read our ext2 DVD-RAMs and that the media changes are now noticed - no more corrupted DVD-RAM disks! I've looked through the mailing list archives but haven't noticed anyone reporting this problem. We're using the stock 2.2.x kernel with the NFS3 patches on (& looking forward to 2.2.18!) with a mix of Debian 2.2 & Redhat 6.1.
