Set n to 1 for one iteration. This is normally sufficient. The

heck n

Check to see if disk has

"data" on it

The -n parameter sets the maximum time in minutes you

want it to run. You will generally set the n value to 1, unless

the disk is partitioned. If that is the case, set n to zero so it

will test entire disk.

the disk, and whether or not there are any repeating patterns

that could indicate there is live data.
