Figure 9 Selecting the Type of Test (xstm Interface)
The color of the device on the device map changes to blue when the test begins. Figure 4-5
shows the progress indicator.
CAUTION: Selecting a Read-Write Test option can destroy the information on the disk. You
must select the Read-Write Test option to check if the writing operation is functioning properly
on new, unused disks. However, a Read-Only Test option only reads the information on the
disk. This test does not affect the information on the disk.
NOTE: You are prompted to select the type of test only if you have unmounted the disk and
mounted it again. If you have not unmounted the disk, the Read-Only Test option is selected
by default.
