Hello everybody

I am in a project related to seagate terminal commands. if you can help, then please give me the seagate terminal command set. or any to the to the file or article, describing about those commands.

Thanks in advance

Seagate Diagnostic Commands

Upon power up, the drive will respond to a set of diagnostic command send through serial port. Because of the number of commands supported, the commands are broken up into ‘Levels’. Many, the progress may be sent over the serial port for number of bits written and read, and command such as read, write, seek, and error log manipulation are available at several different levels. Diagnostic commands are used in place of ATI scripts to do testing. While the drive is running these diagnostic commandshard/soft error rates, a number indicating the test currently being performed, and various information for status of the current test.
The firmware consists of 2 flash codes and numerous supporting files. The two flash codes are known as factory code and customer code. The factory code contains all the serial port diagnostics command but no AT interface command. The customer code contains all AT interface command but minimal set of serial port diagnostics command.
In the ‘Availability’ column, a ‘F’, ‘C’ and ‘B’ indicate the command is available at ‘Factory Code’, ‘Customer Code’ and ‘Both codes’ respectively.
The following is a short list of some of the serial port commands:
Level T - Certification Tests.
Download code
Start manufacturing test
Set drive ‘Age’
Commands to read cert logs, read error logs, write test data to flash, etc.
Level 1 - Memory Control Commands.
Commands to display buffer, display memory, set memory, copy buffer to flash, read
sysvars from disk, etc.
Level 2 - Drive Level Commands
A command to configure the cylinders, heads for testing, gives option for random
cylinder/head and random data patterns
Commands to set data patterns, perform ECC tests, manipulate the error log, dump the
sequencer ram.
Commands to do physical to logical conversion, assign skips and alternates, etc.
Commands to spinup, spindown, seek, read, write, read long, write long, read compare,
sleep, set retries, etc.
Level 3 - Seeking Commands
Display the zone table
Motor acceleration test
Measure head switch & settling times
Display head offset
Move actuator open loop
Seek, seek physical, varying length seek test
Latch test
Display position of actuator
Hysteresis test
Latch Exerciser test
Level 4 - Servo Tracking Commands
Manipulate a skipped cylinder table
Tracking error test
Page 1
Display position error signal
Zap servo burst
Set servo offset
Set/display tracking gain
Send impulse to actuator

Уровень 5. Используется только взаводских условиях Уровень 6 – Команды batch файлов
Batch файлы для тестирования запусков-остановок, переключения головок, CSS, тестов 1, 2, 3 коррекции burts, files to test start-stop, head switch, CSS, 1,2,or 3 burst correction test, назначаемые тесты, тесты сравнения данных, возможность вводить различные batch файлы в RAM. Level 7 - Adaptive Control Commands
Tune parameter control and display
Diagnostic read track
AGC gain control
Perform VCO calibration for all zones

Level 8 - Special Packwriter Commands
- Servo diagnostic sub commands
- Configuration commands
- Lock spin external, spin speed adjust
- Set actuator bias current

Level 9 – Drive Level Command (Full-slipping Defect Management Mode)
Beside the above nine levels of commands, there are two additional sets of commands, the On-line commands and Common commands. The main purpose of On-line command is to display varies type of status. Common command is use to ‘poke’ and ‘peek’ into memoery to allow access to registers, buffer memory and data memory.
2.1 ON-LINE COMMANDS

ASW WORD
The Algorithm Selector Word (ASW) is a command to tell the flash upgrade routine to select the correct flash programming algorithm. It can be issued as a parameter in the SDLE.EXE software. The idea is to have single generic routine to cater for different flash memory programming algorithm. Typical flash programming involves ‘word programming’ and ‘sector programming’. If a new flash vendor is cut in, the firmware is not required to change. Just use the correct ASW will do.

What are the default COM parameters (baud, databits, stopbits, parity) for the Seagate diagnostic port? I can stumble around trying different combinations, but would prefer knowing before hand.

Can you please clarify how to access a hard drive from the serial port? What is the step-by-step of doing that?

Is there is a way to open a terminal window (like Windows command line or Hyperterminal) to control and repair a hard drive's firmware using typed-in commands? If so how? I'm hoping that there is some way to open a terminal Window and then type "help" or something like that, to display a list of all the hard drive's commands and command switches, similar to Windows and Linux command-line commands. It seems a bit ridiculous that people are being enslaved to the greed of people who sell the PC-3000 etc., instead of resourcefully finding and sharing free or cheap do-it-yourself workarounds.
Thanks.

If you insist to start DIY+RYD :mrgreen: (do it yourself and risk your data), then surch in the forum:

- all questions are allready asked somewhere
- a lot of answers given

The information on how to make and use a serial com port adapter have been on this forum for many years now. The commands for older drives are listed above for free. Please keep in mind that inputting a wrong command will render your drive useless. Nobody is enslaved to use AceLabs products.

Is there is a way to open a terminal window (like Windows command line or Hyperterminal) to control and repair a hard drive's firmware using typed-in commands?

Not always. Can only perform some action. Luckily there are a lot more complex protocol(s) to know to do what you want to do, and not all the drives have terminal access.

If so how?

Ah, simple : pay for the knowledge. Everything in this crazy life has a cost. There are things that cannot be bought, for everything else, there's MasterCard (if you prefer : Amex. Don't like Amex either ? Visa.)

I'm hoping that there is some way to open a terminal Window and then type "help" or something like that, to display a list of all the hard drive's commands and command switches, similar to Windows and Linux command-line commands.

Hope is the last thing to die. After a lot of research, luckily at drive factory they are so greed and nasty that they had not provided anything like that so we had to work it out. And they are complicating things each generation of drives they put on the market. Oh, my !!

It seems a bit ridiculous that people are being enslaved to the greed of people who sell the PC-3000 etc., instead of resourcefully finding and sharing free or cheap do-it-yourself workarounds.

Eh... what can we say ? Maybe the users of commercial tools are into sado-maso... But you don't really need any PC3000 etc. to work with drives. These tools are only a solution for automated access to drive internals. If you are good enough, you don't need any tool like that. Or you can write your own.
Naturally everyone expect that OTHER people DO research and "SHARE" :mrgreen:

Thanks.

You're welcome.

Can someone please post a link to a web site which sells a "serial com port adapter" for a hard drive? Or post the name of a particular brand of "serial com port adapter" which I can then find using Google? If I do a Google search, it leads me to SATA (Serial ATA) hard drives or to serial port adapters which connect to devices other than to a hard drive.

Search for MAX232 on ebay

For which pins to connect it to on Seagate (and Samsung?) drives , see
<link to follow, as I've lost it...> but several diagrams on the web

NOTE, as other people have said, commands are case sensitive and model specific and randomly entering commands could cause permanent damage

NB I'm in the same situation in that I'm learning about Seagate serial commands
Practise on an old, cheap drive first
And remember many commands are model specific and not generic

Is this is it(MAX232 Serial level converter)? It does not seem to be an adapter that connects to a hard drive though(?). How does a serial com port adapter connect to the hard drive? Is one end of the adapter going to be similar to an IDE cable connecter, for example?
