I have no idea whether the drive does support it or not. Anyway: no, the world ain't as easy as you think it were. :) Supporting features is not as simple as adding a #define to a header file. The actual work is hidden inside a driver, the #define is only the interface definition of the driver to the outside world. The st(4) driver in FreeBSD-current does support the MTRETEN command, and of course, mt(1) has been updated to include it. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
