LCD example, SCSI test
The SCSI tests the functionality of the SCSI ports. This test sets the K2600’s SCSI ID to
7
and
scans the SCSI bus. When it
fi
nds a connected SCSI device (such as an internal or external hard
drive) the K2600 writes random data to each block, then checks to see if data has been retained.
Warning:
The attempt is made to retain user data on an internal or external hard drive by
saving the contents of each block before testing and restoring it at the completion of the test.
However, it is always wise to back up critical data prior to executing this test.
Failure of this test may indicate a problem with SCSI ID settings, a fault of the SCSI device or
connection, or a problem on the Engine Board.
Note

fi
gurations and guidelines, refer to the
