The Solution for Seagate 7200.11 HDDs

4,868 posts in this topic

Hi All, I need some assistance please!

My seagate is in BYS state, it detects in the bios once and then enters the BSY state. I've built the MAX 232 interface but i'm still having issues communicating with the ST3500320AS SD15 drive, i can do a loopback test and i have tried the interface on a seagate 200gb drive and i seem to get a response from that but i can't get the same response from the ST3500320AS. I'm i doing something wrong or is my HD fried? Please can someone advise.

The drive is back up and running now. But...

Have any of you had problems installing the firmware afterwards? I have done everything I can think of to get the Dell DE13 upgrade (R213714) going, but it doesn't do anything. It boots up to three lines of console, then boots directly into Vista. I've tried running directly from command (says conflict with 32bit/64bit), the boot CD, and the boot USB options...

Anyone with some tips?

Please note that if your drive is connected to an add-in or onboard controller designated for SAS (Serial Attached SCSI) then you will need to connect your drives to the onboard SATA controller to perform the update.

I have followed the instruction as yo how to connect the RX TX from the interface to the HD's TX RX.

I have some spare drives but not the same as the ST3500320AS SD15, when i connect the ST3250310A to the interface i can read info coming from the ST3250 but not ST3500. all terminal settings is as described on post #1. The out put voltage is of the interface is just under 5v, there was a moment were there was a response but i can't seem to get back to that stage i'm checking over my circuit to make sure it's working 100%.

Hi Jhothagondyaz, Firstly many thanks for your response it's very much appreciated.

post-251167-1247311326_thumb.jpg

this was the result i got back when i attached the 320gb drive at 9600bps but when i do the same at 38400 8-N-1 with the 500gb i don't get any response form the drive. Any ideas?

The GND wire is connected?.

The hard disk makes strange noises?

The operation of the disk is normal?

Put your hand over it a bit.

GND connected - yes

no noises

operations normal - gets detected in bios once only

hand over - spinning, no heat

i tried isolating the head as well, still the same.

Did you wait a few seconds and then issue a CTRL Z ? :unsure::

With the data wires plugged in from the drive to the serial adapter pins, it's time to plug the SATA power connector from your power adapter into the drive that has been prepared with the cardstock. Once you've done this, wait about 15 seconds and hit CTRL-Z (that's the CTRL key and Z key simultaneously) in your HyperTerminal session. What should appear on the screen follows below.

Remove the power of HD.

Completely remove the PBC's HD.

Careful not to disconnect TX, RX and GND.

Putting power to the HD.

Ctrl + z on Hyperterminal.

i'll try that Jaclaz but i just noticed that the RX TX voltage output is 1.2v is this to low?

This adapter uses four lines: +5 V (or +3.3 V), GND, RX and TX.

jaclaz thank you for joining in with you help

maybe this is my issue but when i use the inter face on another drive it works but i just checked the interface without it being connected i get 0.8v (maybe suspect) i do have another usb to serial but this voltage output is 6.2v which i think it's way to high but then i know this usb - serial converter is 100% working, is any way i can reduce the usb converter voltage to use on the drive.
