Operation
Disk Test
Use this mode to test the integrity of the readability and writeability of the
target drive. This mode will read blocks of data from the target drive, save
the data in RAM, write a test pattern to the same area of the target disk,
read back and verify the test pattern, write the original data back to the
disk, and verify that the original data was written back correctly. If any
errors occur, the process will be stopped and the errors reported. The test
process will be repeated for successive blocks on the disk. The front MB
and back MB fields will specify what portion of the disk will be tested in
this manner. The default values are set to test the full disk: Front MB =
65535 and Back MB = 0. If you only want to test a portion of the drive,
you can specify different Front (begin) and Back (end) parameters to test.
The second and third lines are used to set the Front and Back parameters
to limit the test operation to specific parts of the target disk. By default,
the Front is set to the total size of the drive in megabytes. To change the
settings, press “SEL” to select front or back and use the
éê
keys to change
the values in 100 MB increments.
To start “Disk Test”, press the “START” key. The next screen will prompt
you to confirm the action to start. Press “START” again.
The next screen will display a progress bar showing % completed in 5%
increments or the file name during the copy process, the transfer speed and
estimated time remaining.
If “STOP” is pressed during a copy operation, the screen will display an
“Are you sure” question. To reduce the possibility of an accidental stop,
the “STOP” button must be pressed twice to cancel the operation.
