Hi.

I posted some time ago with regards to writing to a windows partition (here), however, I have done much more research and need some more help if possible.

Basically, the new goal is reading/writing to a DVD in linux (CentOS). I have been looking on google but havent found anything to help me. All I really need to do is access (read/write) a DVD; I will be using my own contiguous file system, so will need to be able to read/write to individual sectors minimum.

Also, the data wont all be written in 1 go, it will be added to/read from at different times.

Any info will be appreciated.
Thanks.

all my knowledge of DVD access in linux stands in growisofs and k3b. But i guess you're more looking for a sort of hdd-like access to the medium itself (like, operating directly on /dev/cdrom), right ?

"Package Writing" is the keyword here, the underlying file system is called UDF. There's a kernel option "UDF file system support" under File Systems / CD-ROM/DVD Filesystems, and another option "Packet writing on CD/DVD media" under Device Drivers / Block devices.

Unfortunately that's about all I know about it, but perhaps that helps you googling for it.

That is correct.

Thanks! It has definately given me something to research. I have had a quick look and packet writing/UDF should allow me to access the disk like the hard disk/floppy. This means I now need to find out how to access a hard drive directly, which should be easier to find out ;D

Thank you for your time.

Such as using ATAPI ??
