A precise answer would be "not applicable" or "OVERWRITEABLE". We try to squeeze those media into our CD inspired media models. The MMC specs clearly state that a BD-RE is random access overwriteable. Like DVD-RAM or like a SCSI hard disk. So there is no "write mode" as with CD. One writes. Period. > cdrskin: NOTE : greying out all drives besides given dev='/dev/sg1' Your operating system seems to be a kernel 2.4. (Else cdrskin should use a /dev/sr* address rather than /dev/sg* ) On modern 2.6 it is supposed that one can write to the formatted area of BD-RE via the plain block device. dd if=test.iso of=/dev/sr0 bs=32K On kernel 2.4 this would work with DVD-RAM. No idea whether your kernel will accept BD-RE. If this works, cdrskin should be able to use this drive address and declare the media a "stdio-drive": cdrskin --allow_emulated_drives dev=stdio:/dev/sr0 ... --------- My interest as burn programmer with BD-RE is about completeness iof the media zoo and later the finer stunts, like disabling the slow verification process and defect handling. For that i need to learn how to handle it by MMC commands directly. (The stdio: drive uses POSIX calls to talk to the block device driver which then issues MMC commands. I would have to guess ioctls to do stunts.) I'm still testing whether i understand the reason for today's failure and hope to have found a remedy. For now it looks like a small negligence in predicting the pseudo-capabilities of the media. The false speed factor and the false RAW mode have turned out to be mere display bugs with no further consequences.
