As suggested, I have re-run tapetype on the drive, leaving out the -e
[estimate] argument:

----------------------
$ time sudo -u backup tapetype -f /dev/tape -t DDS2-120m-no-estimate \
&& echo Ok.

define tapetype DDS2-120m-no-estimate {
    comment "just produced by tapetype program"
    length 3751 mbytes
    filemark 3 kbytes
    speed 301 kps
}

real    428m24.768s
user    0m2.700s
sys     4m15.500s
Ok.

----------------------

Both the length and speed values are somewhat lower than before, but the
most significant difference is in the filemark value, which looks much
more reasonable now.
