Seagate diagnostic instruction set for research purposes only
After turning on the power, through the serial port, hard drive will respond to a series of diagnostic commands. Because there are a number of command support, these commands are divided into different levels (Levels). These commands sent t o the hard drive via the serial port, for example: read, write, find, and displa y the error log. Can be operated at different levels of access. These diagnostic commands can be used to replace other advanced technology to detect Seagate har d drive. When the hard disk and running, these commands can be pointed out that the hard drive diagnostic software and hardware errors, this time the response o f test results and the information is fed back to the current screen.
Firmware (firmware) that contains two flashi codes and several supporti ng documents. This two flashi codes by the composition of the factory code and u ser code, factory code contains all of the serial port diagnostic command. AT co mmand interface, but does not include, and the user code contains all of the AT interface commands, but very few serial port command.
In the following list, the letter 'F', 'C' and 'B' represent the factory to supp ort the command code, user code and common code.
The following is a brief list of the serial port command: Level T - validation test
Download the code Begin to create the test
Set the hard disk's age ('Age')
Issued instructions read various logs, write test data to Flash, etc. Level 1 - the memory control command
Send command to display the buffer memory area, set the memory area, CO PY the buffer content to Flash, from the hard disk read-out system information Level 2 - Driver Layer command
Command to configure the hard disk cylinders and heads to test, given i n random cylinder head and the option to random data
Set the data mode, the implementation of ECC check, control error log dump seque ncer ram.
To do physical and logical address translation, distribution or replace , and so designated
Motor from the switch, stop switch, find, read, write, read and write the length of comparison, the motor Sleep
Level 3 - Addressing the command server
Display the contents of the firmware area The motor acceleration test
Conversion and set the time of the test head Display head offset
Slide open the loop
Find, find the physical address, a variety of lengths to find the test Latch test
Shows the location of the transmission shaft Hysteresis test
Level 4 - Servo Seek command

Level 7 - Correction Order
Adjustable parameters to control and display Reading Diagnosis hard track
Automatic Gain Control (AGC)
In all regions of the calibration of voltage controlled oscillator Level 8 - filled with write command
Diagnosis of alternative command servo Configuration commands
External spindle lock, speed control Series voltage current actuator set
Level 9 - Driver Layer command (the deviation of all defect management mode) In addition to these nine levels of command, as well as two additional commands: on-line orders and general orders. The main function of the command line is to show the status of various types, common command is used to access the registry by monitoring the memory cache and data memory.

2.11 LEVEL 9 COMMANDS: skip the whole defect pattern error
level 9 command basically support includes level 2 of the order. The only differ ence is you can skip all of the defects, marked by logical sector alternative se ctor, cylinder and head of the code and LEVEL2 the same.
For example:
For example, a physical track composed of 12 sectors, and of which 3 are defecti ve, if the L2 W command will mean written in 12 sectors, but in the L9 will be r ecorded in the W command and skip it into nine 3 defective sectors.
W2, 4 in level 2 means that the physical sectors included in 2,3,4,5 (physical s ector 2,3,4,5).
W2, 4 in level 9 means that written into the logical sector 2,3,4,5 (physical se ctor 2,3,6,7).
L9 state law in all sectors are "error skip mode"
Note: Due to locate the cause of LBA, the following defects in the 4,5 sector ca n be read and L2 L9 in the same instruction can not.
Column in which access level, the letter 'F', 'C' and 'B' represent the factory to support the command code, user code and common code.
The letter 'P', 'S', and '*' represent the support of the command 'fill write mo de', 'Servo Mode' and 'Special Mode'
