or

a green icon. To test a drive, you must have at least 50 MB of free disk
space on the drive.

Under Test Settings for All Selected Drives , drag the slider to set the
size of the test files to be created. You can select Fill x% of disk
capacity to set the file size according to a percentage of the total disk
space on the drives you’re testing. To get the most accurate results,
your test files should fill about 80% of the disk capacity.

reading (playing back) a single video file.
