https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230649 --- Comment #13 from scdbackup@gmx.net --- Hi, so i can cancel my plans to explore Linux UDF capabilities with sequential media. Your previous success report was not unplausible, because UDF indeed defines usage models for such media. But i am not aware of an implemented UDF driver in a free operating system which works according to that model, which Wikipedia calls "VAT build". https://people.freebsd.org/~scottl/udf/index.html calls in its TODO for volunteers to implement VAT. Customers for VAT would be the sequential media or media states:=20 CD-R, unformatted CD-RW, DVD-R, DVD-R DL, DVD+R, DVD+R DL,=20 unformatted DVD-RW, BD-R not formatted to Pseudo-Overwrite. Traditionally one needs a burn program to write to them. The other family is called "overwritable": formatted CD-RW, DVD-RAM, DVD+RW, formatted DVD-RW, Pseudo-Overwrite formatted BD-R, BD-RE. If the operating system recognizes it as overwritable then the medium is usable like a slow hard disk or a slow USB stick. But it might not last long until the medium dies under the random access load of a hard-disk-oriented read-write filesystem. Burn programs are usually less torturous to drive and medium, because they mainly work sequential. (I also fail to find for FreeBSD something like Linux pktsetup(1) which would be needed for using formatted DVD-RW like a hard disk.) Have a nice day :) Thomas --=20 You are receiving this mail because: You are the assignee for the bug.=
