1 Checking content The hard disk drive standard values (Memory capacity, Number of cylinders. Number of heads, and Number of sectors) are displayed. 2 Display
Drive Status display hard disk drive information Drive Type : xxxxxx Capacity : xxxxMB Cylinder Number : xxx Head number : xx Sector number : xx Press any key to exit.

Details of error are displayed.

ESC : Exit SPACE : Stop or Start

Select the desired items at the position of @. (@ is not displayed on the screen.) On the above screen, when the pass count is counted up (when the point is counted up to the upper limit set in the cylinder range setting, the pass count is counted up by 1.), and if the error counter of all error items are not counted up (remaining as 00000), the test is OK. When the space bar is pressed during the test, the test is interrupted. When the space bar is pressed during interruption of the test, the test is started. 3 Terminating method Press the Esc key during execution of the test or during interruption of the test to terminate the test and return to the above menu screen.

Press any key to terminate the test and return to the menu screen in the previous (1).

2) SEQUENTIAL SEEK TEST
[Test conditions setting] � Cylinder Range [0 ~ inmost cylinder] The cylinder range to be tested is set. � Retry Count [0 ~ 4] Retry count in case of an error is set. � Error Stop/Continue/1 Pass Selection is made among Error Stop/Continue/1 Pass in case of an error. � Test Start ? [Yes/No] Selection is made to execute the test or not. 1 Checking content In the cylinder range set above, the sequential seek is executed for every 1 track. When the seek test in the set range is completed (in the direction of 0 3 inmost cylinder), it is counted as 1 pass. In case of an error during the above test, a retry is repeated up to the set number of retries. Every time an error occurs by executing retry up to the retry number and error logging is performed. Logging is made for HD and DRAM. When an �Error stop� is set in the test conditions setting, and an error occurs during the above test, the error display is made and the test is stopped. Press the space bar to resume the test. When �Continue� is set, even if an error occurs, the error display is made but the test is not stopped. When �1 Pass� is set, a series of tests is made only once and the test is stopped.

3) RANDOM SEEK TEST
[Test condition setting] Same as the above sequential read. However, execution of the test by 1 Pass means execution of random seek through the set cylinder range. 1 Checking content The random seek is executed for every one track in the cylinder range set previously. When the seek test is completed in the set range, it is counted as 1 pass. In case of an error during the above test, a retry is repeated up to the set number of retries. Every time an error occurs a retry is performed up to the set number of retries, and error logging is made. Logging is made for HD and DRAM. When the �Error Stop� is set in the test condition setting, and an error occurs during the above test. The error display is shown and the test is interrupted. Press the space key to resume the test. When the �Continue� is set, even if an error occurs, the error display is made but the test is not stopped. When �1 Pass� is set, a series of tests is made only once and the test is stopped. 2 Display Same as the above sequential read, however the following contents are different. The test Point is changed at random in the range of 000 ~ XXX (cylinder range set value). Each point is tested once, and the pass count is added by one with XXX times. 3 Terminating method Press the Esc key during execution of the test or during interruption of the test to terminate the test and return to the above menu screen.
