It is possible to start the hardware self tests of hard disks. Such tests are able to examine the hard disk components (servo, heads, electrical components, internal memory, etc.) in a more reliable way than software based tests (for example, scandisk).
The extended test also verifies the disk surface: reveals any currently hidden problems with the hard disk and forces the review of pending sectors and reallocation of sectors if required - but without the risk of data loss.

This message "Test Failed By Read Element" is usually displayed if the test cannot be completed because of a problem occured during this test when examining the surface area. This is more common if the drive is not 100% perfect (I did not see the current health and the exact problems with this drive (if any) displayed in the text description area).

Because these tests are hardware based, from software it is not possible to control the execution, we can just examine the current status of the test. The 79 means that error "7" occured (this is the read element = the head) and the "9" means that 90% of test is still remaining - so the problem occured at the beginning of the test.

I'm working on different test method which can be used in this situation or when a drive has no hardware test at all.
