works more efficiently.
NOTE: Do not defragment an SSD.
Tips & tricks For optimal system performance, place your operating system and all of your most commonly
used applications and files on the fastest hard drive (solid-state drive) and fastest areas on the
drive (primary partition of 200 GB max).

sure that the drive is functional.
If all of the tests are successful, see Common blue screen error messages on page 174 for detailed
troubleshooting steps.
Noisy hard drive
