HDD SELF TEST
■HDD SELF TEST
Before using the HDD attached to this unit, test the HDD whether to be used correctly. There are 3 types of the test
method and choose one in the <HDD SELFTEST> screen. When choosing, refer to the table below which describes the
details of each method.
When the HDD is newly attached for recording, it is recommended to execute “READ/WRITE TEST” and
format all the area of the HDD before it is used for recording. Be sure that all the data in the HDD will be erased
when executing “READ/WRITE TEST.”

In addition to the compatibility test,
criticizes the partial sector defects in
reading or writing. Also uses for the
screening effect by ageing or for erasing all
the data when dumping the HDD.
The recorded contents will not be affected when executing “QUICK TEST” or “READ TEST.” When executing
“READ/WRITE TEST,” be sure that all the recorded contents of both HDD (A and B) will be erased. When you
execute “READ/WRITE TEST,” attach one HDD to be tested and remove the other HDD with the contents you do
not want to erase.
This function temporarily tests the HDD whether it will be used correctly, and not completely criticize the defect
involved in the HDD.
