This test checks some of the hardware aspects of the drive itself, including the controller I/O, memory, and head-positioning mechanism. These universal tests are applicable to almost any drive type. Some of the tests can even be performed on CD-ROM drives. These tests include:
• Diagnostic Check
• Format Check
• Rezero Unit
• Spare Sector
• Supply Voltage
• Unit Ready
Unit Ready Check
This test determines whether the target drive is able and ready to receive commands.
Unit Ready Check <Unsupported. (9)>
Supply Voltage Check
This test checks that the voltage to the drive is within acceptable limits.
Supply Voltage Check <Passed>
Diagnostic Check
This test initiates a self-diagnostic on the target drive. These routines are designed by the drive manufacturer and provide excellent insight into the operational condition of the drive electronics and mechanism.
Diagnostic Check <Passed>
Rezero Unit
This test is used to determine the target drive's ability to position the actuator at cylinder zero.
Rezero Unit <Unsupported. (9)>
Format Check
This test establishes whether the drive was properly formatted during initial setup.
Format Check <Passed>
Spare Sector Check
This test checks the service tracks to determine whether there are enough spare blocks left for bad block repairs.
Spare Sector Check <Passed>

Confirms that data can be reliably written to and read from various locations on the hard drive. These tests include:
• Read Buffer
• Write Buffer
• Linear Read
• Linear Write
• Random Read
• Random Write
• Seek
Read Buffer Test
The Read Buffer test is used in conjunction with the Write Buffer test as a diagnostic function for testing target memory and bus integrity.
Read Buffer Test <Failed! (-4)>
Write Buffer Test
The Write Buffer test is used in conjunction with the Read Buffer test as a diagnostic function for testing target memory and bus integrity.
Write Buffer Test <Failed! (-4)>
Random Read Test
This test reads data from a random memory location, verifying the ability of the device to retrieve data.
Random Read Test <Failed! (-4)>
Random Write Test
This test writes data to a random memory location, verifying the ability of the device to store data.
Random Write Test <Failed! (-4)>
Linear Read Test
The Linear Read test checks the ability of the drive to read data from a linear data segment.
Linear Read Test <Failed! (-4)>
Linear Write Test
The Linear Write test checks the ability of the drive to write data to a linear data segment.
Linear Write Test <Failed! (-4)>
Seek Test
The Seek test provides a test of the initiator to position the device in preparation for access to a particular logical block.
Seek Test <Failed! (-4)>

Media defects can cause the Read/Write tests to fail. Run the Surface Scan test to check for this.
With SCSI drives, sometimes one faulty drive can cause another drive to fail. Termination problems can also cause the test to fail. Disconnect all drives except for the one in question and run the tests again. If the failure continues, the device may need to be replaced. If not, this would be indicative of an external element causing the drive in question to fail. Try rearranging the connection order of the devices.
Finally, if all else fails, try backing up the data on the drive and reformatting it. Then rerun the tests.

S.M.A.R.T. stands for Self-Monitoring Analysis and Reporting Technology. This test checks and reports on the status of the S.M.A.R.T. routines built into your drive. These routines monitor important drive parameters as your drive is operating. An examination and analysis of these parameters can aid in the prediction of drive failure. This will allow you to back up your data before your drive fails and the data becomes inaccessible.

Bad blocks are areas of media that cannot store data reliably. All hard disks have a few bad blocks when they are created, but these are "mapped-out" by the manufacturer when the drive is formatted. Mapping out bad blocks prevents data from being written to these defective areas of the media. Occasionally a good block will go bad. If this occurs and a file resides on that block, the file may be damaged. TechTool Pro will scan your drives for bad blocks and report if any are found.
Surface Scan
The Surface Scan test reads data from every block on the drive to check the integrity of the drive surface.
This test checks your hard drive for bad blocks. Blocks are sections of your drive which hold data. It is not unusual for a drive block to eventually fail. All drives employ a mapping scheme which allows bad blocks to be "mapped out" so that they are no longer recognized by the file system. ATA drives should do this automatically unless their bad block table is full or the bad block is in a critical area of the drive.
If bad blocks are reported the only cure is to reinitialize the drive with the option to zero all data. First back up any data since this will erase the drive. Use Apple's Disk Utility or another disk formatter with all checking and mapping options enabled.
