[QUOTE="ScaryBob, post: 400237, member: 48523"] Turn off Indexing Service in Drive Properties for all drives. If a disk optimizer/defragger is running it could also create disk throughput issues. Some other disk utilities and drivers can slow down disk access. Check anything that is suspect by disabling or uninstalling it. I also disable System Restore for all drives.
