Hi all,
I have a 2Tb Seagate barracuda [7200.14 / model ST2000DM001 / FW:CC4H / date: 13084] thats no longer detected in bios.

Recently I received a "Windows System Error- Unknown Hard Error". I restarted back into windows, saw the standard "windows recovered from a serious error" message, but before seeing the details, my system froze again. This time though my drive was gone. It doesn't appear in disk management(using a secondary windows install on another drive at the moment) or in bios. I also tried using an external enclosure(dual thermaltake enclosure) and got no detection(the dead drive actually prevents other drives in the enclosure from being detected). When powered, the drive seems to spin normally(no noises other than the drive spinning), though I noticed that once it spins up to a certain degree, it remains constant. I'm hoping some one knows or can help me diagnose whether this is a problem with the mechanical failure (heads, stiction, spindle motor) or PCB problem from the information provided. While I'm not new to electronics repair, I've never attempted to repair a drive before. I will soon be acquiring a TTL adapter for testing purposes.

The majority of data on the drive is no longer backed up, my kids destroyed my backup drive a week before this all happened so I'm hoping to revive this drive. While there is quite a bit of data that's important, the cost of data retrieval is a bit too steep. So I'm hoping for a DIY fix. Any help would be most appreciated.

Mostly, none of the above faults, and maybe firmware problem.
A terminal report would be helpful.

Watchout for DIY risks too (as data is important)

Most likely it's not a DIY job. Nut if you want to try you will need at least a tll adaptor and post a terminal log .... Maybe someone is willing to help you for free.

unfortunately the TTL adapter I ordered was placed on back order for the next few days, so it may be a few days before I'll be able to get any readings off the drive. I'm hoping sathyan is right, and that it just a problem with the firmware as I've been reading that their one of the simpler problems to fix.

Be aware that the STANDARD 7200.11 FIX Posted on the net for BSY/LBA0 problem will NOT WORK on 7200.14 drives and not only that but also will make you loose ALL DATA on the drive, or at least make it WAY HARDER to recover.

TLL adaptor without prooper knownledge and tools is even worse than no TLL adaptor.

Firmware problem, if confirmed, might be easy to fix to someone with decent tools (PC-3000) and decent know how. Don't mess with it if you need the data on the drive. Stay away from inputting commands on terminal. Post a terminal log (what the drive shows when power-up connected to the terminal) but DON'T INPUT ANYTHING unless some expert here tells you so.

Aplying a standard 7200.11 fix on this drive is equal to saying goodby to the data.
Your data, your choice.

Hi everybody,
I have a 2Tb Seagate barracuda model ST2000DM001 / FW:CC4B.
My BIOS not only can't detect the HD but the BIOS itself dosen't start if the HD is plugged in.
I thought that maybe is the same problem that backuphero has.
First of all I apologizefor my bad english.
I bought a serial interface MAX3232 RS232 TTL 3V to communicate with the HD, because I thought it was the well known "BSY Seagate" bug, but it seems it's not like that.
When I open the Hyperterminal and press CTRL+Z, the only message I get is a continuously repeat:

LED:00000047 FAddr:FFFFFFFE
LED:00000047 FAddr:FFFFFFFE
LED:00000047 FAddr:FFFFFFFE
...
and so on.
I can't even put any command!

I'm totally newbie in dealing with Hard Disks, any help would be really appreciated.
A question: Buying a new identic hard disk and transplant "the green logic board" from the new one to the "broken" one would help?
Thanks in advance.

Looks to me like some bad areas in SA, or head unable to read part of the SA.
This IS NOT the typical 7200.11 bug.
If data is importnat stop messing with the drive and send it to a data recovery lab near you, or contact someone from italy, like BlackST. He will help you at a reasonable HDDGuru friend fee, almost for sure.

Another PCB will not solve anything, because the firmware is written on the platters and you would need to transfer ROM from one pcb to another and the problem would be the same ..... It's not PCB related.

Spildit, How can I attract attention of BlackST in this forum?
Is this the way to tag him?

oh my god... :shock:
I hope it does not happen with my HD anymore ..

my spec HD
ST2000DM001
f / w CC43
date 13 017

whether the older fw spekesifkasi HD also affected by the problem?

seagate does it really have a problem???

Hi everyone
My ST2000DM001 (2To) in external USB Dongle works fine, till windows detects some errors (yellow triangle) and the HD seems disconnected,to use it i must disconnect and reconnect it, CrystalDisk Info tells me too about Some errors.
I buy and second HD to Backup my datas (2To of Music, photos and home movies).
At Home after preparing the new one, the First (ST2000DM001) dont work anymore and are not detected by windows, after power on, he just start spinning and after some seconds, he make some Clicks (11 Clicks) then stops.
Even if i plug it directly to my Sata plug (inside my PC).the same thing happens (11Clicks and stop).
After contacting Sea*ate, they tells me its a OEM product.
And after contacting Tanscend (USb Dongle Manufacturers), they tells that my warranty was lost after i've open the USB dongle.
Now i'm face to a wall.
Is there a way to diagnose what wrong with it (The Heads?, The PCB?, The Preamplifier?.....).
I even tried my old TTL interface but seems dont communicate with it (I just receive random characters in the terminal window).
Anyone have an idea?
Thanks.

Your drive probably got FW or heads problems, to test it is needed to comunicate with drive via TTL

Probably your comunicacions parameters are wrong. i have not info about comunications params here. probably any guru here can write it for you.

Thanks for your answers.
I have a diy RS232 TTL interface that work perfectly with my old 7200.11.
But not with this one.
Is there any schematics around for RS232 LVTTL (i think the problem is the kind of TTL).
The terminal parameters seems ok.
Another thing i noticed, The MCU are very very hot during power on.
Some suggestions?
To resume:
11 Clicks and stop (does this number a code for something, google dont know about it).
No detection in bios.
No traumatic chocs.
Very hot MCU.
Thanks guys.

Hello momo, I have the same problem with ST3000DM001, drive has 10 clicks, and very hot MCU, terminal shows Fail Servo OP =0100 resp 0007 10 times. A colleague has to replacements of PCB !?
What at a friend's terminal displays !? sorry for my English.

For now, i'm searching how to communicate with the PCB via RS232.
I'm serching for schematics of LVTTL interface.
Seagate seems Cursed.

The I/O voltage is much lower (1.8V) on the latest models.
