I have an older DAT drive by Wangtek, model 6130 FS. I started
out with my system running FreeBSD 1.1. The controller is
an Adaptec 1742. I upgraded to FreeBSD 184.108.40.206 ... no problem.
When I upgraded to FreeBSD 2.0.5 ... problem. I had previously
been using tar with a block size of 128k. This did not work
under 2.0.5. It does work with block sizes under 64k. Some
change took place where it now thinks it is using variable
length blocks. Other than that it has worked fine.
