No TTL-connection to Seagate HDD

August 8th, 2023, 12:31

Hello,

i want to try to reanimate a Seagate-drive, probably the well-known stuck in BSY-state-problem, like this: https://sites.google.com/site/seagatefix/

My equipment:
- PC with Windows XP 32bit
- USB to TTL-adapter with different voltages (1.8, 2.5, 3.3, 5.0 volt) and FTDI-chip
- TTL-adapter with fixed voltage at 5V.

My problem: It is impossible to get answer via TTL in terminal with ANY harddrive after CTRL+z. Loopback test (RX and TX connected at adapter) was successfull with both adapters.

My questions:
- i connected RX to TX and vice versa
- RX at HDD is nearest to S-ATA-connector, right?
- which voltage is correct?
- terminal is configurated to: Baud 38400, Data Bits: 8, Stop Bits: 1, Parity: none, Flow Control: none
- the same settings can also found in "device properties" (virtual COM found in "device manager"), which settings are here correct?
- has GND at HDD connected to TTL-adapter? Found some manuals with and without, some use 2 wires, others 3.
- has a non-US keyboard layout any effect?

Thanks in advance!

Ok, got it. Connection works!

Reply to myself:
- Rx -> Tx, Tx -> Rx.
- Rx on HDD is nearest to S-ATA-port.
- 3.3V work in this case
- terminal config as mentioned, but some older HDDs (i tested a 7200.10, part-no ST3320820AS) need 9600 Baud.
- GND was not needed.
- keyboard layout has no effect.

Now my problem.
- not recognized in bios or Windows
- spin runs, no anbormal noise
- Its a Seagate Barracuda ES.2
- ST3500320NS
- P/N: 9CA154-504
- Firmware: SN06
- after SMART-reset i got this output in terminal, any ideas how to fix this drive?:

Thanks!

Is there a manual, how to apply the script?

ZOC should come with a manual.

https://www.emtec.com/zoc/index.html
https://www.emtec.com/downloads/zoc/docs/zocenglish.pdf

See these sections of the manual:

1.1.1.3 Direct Serial Connections Quick Start
1.8.4.1 Serial/Modem and Serial/Direct Overview

Choose "Serial/Direct".

Sorry for asking again: ZOC seems similar to a terminal application.

Is .zrx a batch/command file or is it written to connected HDD? A quick explanation would help to understand.

Ok, got it working under Windows 7 x64! :D

Now i'm able to execute the script "ST_congen.zrx" or "ST_congen2.zrx".
Which is the right one and which variable has to be set to Yes or No?

Hello,

i executed the "ST_congen4"-script from here: https://www.hddoracle.com/viewtopic.php?p=10886#p10886

Now i get a message while starting:
Drive AMPS Configuration has been modified from compiled defaults.
Drive must be re-initialized to controller firmware defaults by re-downloadingcontroller firmware


But i still get also the "Initiate Mark Pending Reallocate Request for disc_lba:"-messages after startup.

What to do now?

Hello,

i tried the script a second time and noticed that it didn't finish complete, look what:

invalid_cmd.JPG


So i guess some commands are unknown for the drive and the script stops at this point and can't finish?

Thanks!
