Well, maybe. Assuming that the DAT drive can do at least 9MB/min
(my old Archive 2550X DAT drive probably cannot do this), probably, if
you burned in 1X mode (150kb/sec). Burning in 2X mode would require the
DAT drive to deliver at least 18MB/minute; I think some DAT drives can,
but not all.
Of course, I don't know if burning in 1X mode will work, but I
assume that it does (I'm running a bit low on disk space, and so I may
try a 1X burn with the image accessed via NFS).
