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 does not completely criticize the defect involved in the HDD.
