Driver Developer Conference
Nov. 11-14, 2003, Redmond WA. WD-3 was there and taking

The first was that Microsoft is strongly committed as never
before to support the device driver community with good
documentation, training and the personal attention of the relevant
experts.
The second major theme at the conference was LONGHORN -- the next
Windows operating system.
Can you say “paradigm shift” or does the line “Gee Toto I
don’t think we are in Kansas any more” bring anything to mind?

Adventures in Luserland: Finding Disk Sectors

by Mark Roddy
Recently a client was having a problem with data corruption while

requests. It turns out to be unreasonably hard to figure out which
physical sectors a particular disk file occupies, but Mark has a
