Constant Disk Activity

While running MSDE it looks like the service hits the disk every 30
45 seconds. Any hints as to if / how to configure the service to not
hit the disk so often?
Do you have any reason to believe that is kind of activity is unusual? Are
there any clients connected to the MSDE instance that are doing extracting
data or doing updates or deletes? If data pages are being changed the the
Lazy Writer will be flushing them out to disk on a periodic basis.

|||Our application only connects with and interacts with the database
infrequently. We are seeing this disk activity constantly, whether
there is any application currently accessing the database or not.
|||You might try using Filemon from www.sysinternals.com. It's a free utility
that can show any file acivity on your system by any process, including SQL
Server. You can use it to see exactly what process is hitting the file
system and what file it is accessing.

Why are you worrying about this? What problem are you trying to solve?

|||The hard drives that our product will be running on have a finite
lifetime (i.e. only a certain number of continuous hours of
operation). With MSDE constantly accessing the disk, the disk is
never able to spin down. Thus, the life of our product will be
significantly shortened if we cannot stop MSDE from making these
constant disk accesses.
|||We have used a similar tool to determine that MSDE is constantly
hitting the disk. It doesn't really matter which file it is
accessing. What we need is to find a way to stop MSDE from causing
this constant disk activity.
