	Strange .. not ten seconds before I read your message I was marking
some sectors bad on a machine across the office. =-)

	You need a newer badsect, because the version you're using tries to
access the block device rather than the character device.

	I find it odd that you're getting this error, since you say your
system is but a week old, but the date on /local/src/sbin/badsect/badsect.c
(which contains the modification that fixes the prob) on my machine is
October 14. Maybe you forgot to upgrade some parts of your system?

   Interoperation with matter-transporters using polar coordinate
   systems is discouraged, due to round-off and other algorithmic errors
   in certain ubiquitous floating-point implementations, leading to
   results which are best discreetly described as "disappointing." --RFC 1437
