"Stop all exchange services (put them on disabled state)"
It is NOT necessary to stop Exchange services in order to defragment.
Microsoft's defrag APIs fully support defragmenting without first having to
stop Exchange or SQL services.
"Never defrag a drive which has online exchange databases or transaction
logs."
This also is incorrect. Microsoft's defrag APIs fully support defragmenting
drives with these files on them.
