Does it? i just want to have a filesystem (growisofs can do that) and in that filesystem i want to write to one continuos file (of which i dont know the size untill i am done (would it be that bit requireing write access?)). > Unfortunately not all DVD+capable units are capable to sustain true > random I/O, see > http://lists.debian.org/cdwrite/2003/cdwrite-200309/msg00015.html and > follow-ups.

A. i guess i can give up the "filesystem and filenames" bit, if i figure out how to access the later incremental backups. would that work with growisofs just as with a sequential streamer device? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
