Okay, so I've done it myself already, with the help of a 5.2-Release-p1=20 =46reeSBIE from GUFI. The Linux used is still the Knoppix 3.2 from the prev= ious=20 tests, with udftools 1.0.0b2 compiled from source. The numbers in the table indicate the UDF version. | Linux | FreeBSD | Windows | Windows | | (2.4.20) | 5.2R-p1 | 2000 SP4 (*) | 98 SE (*) | =2D-----|--------------------------------------------------- UDF | 1.02,1.50 | NO | NO | NO | Create| 2.01 | | | | =2D-----|--------------------------------------------------- UDF | 1.02,1.50 | 1.01,1.50 | 1.01,1.50 | 1.01,1.50 | Read | 2.01 | | | | =2D-----|--------------------------------------------------- UDF | 1.02,1.50 | NO | NO | NO | Write | 2.01 | | | | =2D-----|--------------------------------------------------- (*) Windows support for UDF filesystems can be extended by driver support from the drive manufacturer, but the set of supported features will differ from manu- facturer, i.e. LG's drivers might support different things than Pioneer's or Plextor's. Below is a table what Windows can do with the drivers supplied by LG for the GSA-4081B drive: | Windows | Windows | | 2000 SP4 (*) | 98 SE (*) | =2D-----|--------------------------- UDF | 1.50,2.01 | 1.50,2.01 | Create| | | =2D-----|--------------------------- UDF | 1.01,1.50, | 1.01,1.50,| Read | 2.01 | 2.01 | =2D-----|--------------------------- UDF | 1.01,1.50, | 1.01,1,50 | Write | 2.01 | 2.01 | =2D-----|--------------------------- Together with the first table I posted, it becomes pretty clear that FreeBS= D=20 systems are de facto isolated with regard to data-exchange over DVD-media -= =20 it's not possible to create filesystems on fresh media which can be read on= =20 any non-BSD systems and the only filesystem besides UFS that's supported wi= th=20 read and write access is FAT32, which does not meet the requirements to=20 properly represent filesystems with common unix-semantics. =2D-=20 ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org --Boundary-02=_waoNA6Bqu5rA7tJ Content-Type: application/pgp-signature Content-Description: signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQBANoawXhc68WspdLARAu6oAKCiRnZk8t/i5CF/lORPIhf6ZNe3NQCeLCM+ 5xg8nPTPTpu6n1mufpSxvq0= =m2U+ -----END PGP SIGNATURE----- --Boundary-02=_waoNA6Bqu5rA7tJ--
