I found these while browsing through the code. My changes to wd.c use two controller flags to indicate the desire to turn off inactivity timeouts, and one flag in each drive's hidden drive word to indicate success (so that status can be checked and/or reported later). It'd be nice to use just the drive flags, but there has to be a way for the user to set or clear the option on a per-drive basis. --Brett
