Ed,
Once you have the unit reassembled and "ready to go", you should
close it up without a disk pack in it and run it with just the
blower circulation for a number of hours before you even think
about putting a disk pack in and spinning it up. This will help
purge out any dust particles remaining in the head/disk area...
