In my particular case I'm using a CD writer in /dev/hdd, thus I edited the file to contain this line:ĭo read the comments in that file but don't bother trying to be creative with the device filenames defined in NEWINTNAMES, else you'll have access permissions trouble later on. It is up to you to take the risk or not.Īlthough the kernel has support for packet writing, you need to install the user space tools to be able to access the kernel services. Now that I've given you dire warnings, let me tell you that packet writing has its uses. In other words, if you think you will be doing your critical data backups with packet writing instead of old-fashioned CD mastering and burning or tape backups or whatnot, you are playing with fire. And they may claim to use the same UDF format version! Furthermore many software vendors in the MS Windows world have managed to make their implementations incompatible to each other, to the point that you may not be able to open for writing a disk created with a different utility, and even fail to read it. In fact, many of you may have used Eas圜D, Roxio's Write-On-CD, Nero InCD, or some other commercial product in MS Windows to read and write CDs, particularly CDRWs, this way.Īs it is the case with floppy disks, reliability is poor any glitch and your data is done for. In essence it allows one to use a CD or a DVD as an oversized floppy disk. That is, to be able to write packets of data. Good question! One of the design goals of the UDF filesystem was to allow incremental data addition to optical media. But trying to understand how to do it can make a grown man cry. It took some head scratching, but then it hit like a truck: You don't need to be a rocket scientist to do it!!!.
Yet I only managed to have it work consistently in Breezy.
The Linux kernel supports packet writing on read-only and rewritable media since kernel 2.6.8, as was the case in Hoary. Python -c 'print "cGFsb3BlenZAZ21haWwuY29t".decode("base64")' Packet Writing Without Tears: How to use Rewritable Optical Media in Ubuntu
