6.3 Diagnostic
The Diagnostic feature allows you to run tests to verify the health of your target hard drives. If
you are experiencing a high rate of failures duing the duplication process, there could be something
mechnically malfunctioning with your hard drives and the Diagnostic functions are a simple way to
verify the health of your drives.
There are three Diagnostic modes available:
•
SMART Check
- (Self-Monitoring, Analysis and Reporting Technology) monitors hard drive
indicators of reliability and is often able to anticipate future failures. SMART checks the
electrical and mechanical performance as well as the read performance of the disk. Electrical
tests can include a test of cache, a read/write circuitry test, or a test of the read/write head
elements. Mechanical tests include seeking and servo on data tracks. SMART Check is disabled
by default.
•
Write Test
- Checks the ability to write data to all sectors on the target hard drives. Write test is
enabled by default.
•
Read Test
- Checks the ability to read data by first writing random data to all sectors on the
target hard drives and then attempts to read them. Read Test is disabled by default.
For information on enabling other Diagnostic modes, please see section 7.8 Diagnostic Setup on page
28.
