ATAPI removables test
This test verifies that the removable disk drive is operating correctly. The removable
drive can be an LS120 drive or an Iomega ZIP drive. The tests include:
• Write test
• Read test
• Seek test
• Soft eject test
Write test
Write TestThis test verifies the ability of the LS120 drive or ZIP drive to write data
correctly to an LS120 or ZIP disk, respectively. You should use a disk that you know is
good for this test. This test is normally hidden from view because it destroys the data
on the disk. Select the drive(s) to be tested and run the test.
Warning: This test destroys all data on the disk.
Read test
This test verifies the ability of the LS120 or ZIP drive to read data correctly in both
block and random sequential format from an LS120 or ZIP disk, respectively. You
should use a disk that you know is good for this test. Select the drive or drives to be
tested and run the test. You can select the starting and ending clocks of data to be read
or you can select the percentage of the drive to be read in a sequential or random
order. You can also run a random or sequential read test.
Seek test
This test verifies the ability of the LS120 or ZIP drive to seek blocks of data
sequentially or randomly. Since most of these drives have a caching mechanism, drive
performance during the sequential seek should be faster than specified by the drive
vendor. The drive performance during the random seek test should be approximately
the same as specified by the drive vendor. Select the test parameters and ruin the test.
You can specify the number of times this test is to be run (repeat count), or you can
specify Quick Test to test only 1% of the disk.
Soft eject test
This test verifies that the auto eject feature of the LS120 drive or ZIP drive is working
properly. You can set the Repeat Count parameter to run this test a number of times.
Select the test parameters and choose Continue to run the test.
