This is (was) dual boot Win7/Ubuntu system. No indication of trouble (although I wasn't checking for it) until one day it wouldn't boot. Wasn't identified by UEFI. Information isn't critical but would be nice to get so want to try DIY. Virtually all the useful files are in the Win7 NTFS partition. I have read that Linux may be able to read the data so could try a linux live CD or plug it into the same PC that has a new hard drive and Ubuntu. But since the UEFI can't identify is this worth trying? I have done a bit of reading on this but I don't have any experience with HDD recovery.

Well, if data is critical you should consult a data recovery pro as chances are that at this stage the recovery costs are not very high.

With that in mind if you don't want to pay and you do want to loose your data for good we need to know a little bit more about the drive.

Does it spin at all ?

Can you ear some strange noised like clicking ? Does it spin down ?

Can you detect the drive with something like MHDD ? Are you connecting the drive directly by SATA and not with a USB adaptor/enclosure ?

Can you plug the drive to a TTL adaptor and post the log ?

What do you consider cost "not very high"? I asked one place and was quoted about $800 and that was just the starting point. Still wanted me to buy a drive to put the image on and the disclaimer it might go higher. How do you find a reputable but reasonable cost place?

In any case I want to try to do this myself as it's not critical I recover the files. I have TTL adapters from other projects that I can use. What are the logic levels? 3.3V? I can measure to be sure.

Direct SATA connection.

It does spin. I will do some more checking, download the programs and get more information.

Any tips on connectors for the TTL interface? The spacing of the pins is odd and measures about 0.070" pitch. The sockets I have are too big to fit. I could get sockets from a smaller pitch and use them.

This is a DM drive that have typical problems like media cache, etc ...

A REPUTABLE data recovery firm that is honest should be able to deal with sysfile 93 and media cache and DOS table if needed and image/clone the drive with PC-3000 DE, extracting your data for something like $300 IF the drive doesn't have physical problems like damaged heads and damaged platters. If you have physical damage the recovery will be $600 or more.

Check for example @LarrySabo pricings here - viewtopic.php?f=3&t=36887

And for VERY CHEAP head stack replacement and clean room work you can try to contact @drHDD - memberlist.php?mode=viewprofile&u=31114

Your major issues are related to the fact that EVEN if you do get the TTL to work and even if you do can apply firmware patches and make the drive "detectable" you will still need to extract the data.

Lacking hardware based tools you should use HDDSuperClone or ddrescue to clone/image the drive to a known working one but it's way better to use hardware based products like PC-3000, MRT, DDI4, etc to do the job as it's very risky to image a damaged DM drive (that will die very shortly) with software only and if you end up killing heads you will need clean room work and the charges will go higher.

As for connecting the TTL adaptor .... Use your imagination ! Just get some small connectors from anywhere that you can and use that on the small space of the "jumpers" of the Seagate drive and connect that to the TTL adaptor socket. Just get something that will fit on the small space of the jumper block for the Seagate and wire it to the TTL ....

Downloaded iso image with MHDD, burned CD, and ran this on PC with new drives to check it out on a good drive before on the bad drive. I get option to select drives:
1. Primary controller
3. Secondary controller
5. PC-3000
All the spaces below the selections are blank - not sure if this should show drives. When I try to select I just get "drive not ready" for any of them. The drives are working fine for normal use though.

Drives are SATA. Motherboard is ASRock Z87 Extreme4. I have looked at MHDD documentation several places and can't see what the issue is.

On the connector I remeasured more accurately and the pitch is 2 mm. This is a very standard pitch, just smaller than I have on hand (Mostly 0.1" stuff) so I will make up something.

I just wrote up a post but don't see it. Is this because of moderation of new member posts? It happened on one of my previous ones but I could see a notice about moderation that I don't see now.

I downloaded the iso with mhdd, burned a disk, and booted it. This was on my PC with new drives to see how it detected a good drive before using it on the bad drive. I got a selection menu:
1. Primary controller
3. Secondary controller
5. PC-3000 board

There were also some spaces between the selections that were blank but appeared to be for disk IDs or something like that. When I tried to select a drive I got "drive not ready" for any selections I tried. I have two SATA drives in the machine that work fine in normal operation.

I looked at several sites documentation but am not able to figure out what I should be doing or what is going wrong.

For the connector for TTL I remeasured more accurately and the pitch is 2 mm, which is a standard pitch. Most of my pin connectors are 0.1 inch so I will have to come up with something. It looks like Samtec series ESQT would work well or I may cut down something I have.

You have to set your SATA drives to IDE/COMPATIBLE mode on BIOS so that MHDD can pick them up ...

Set to IDE. MHDD detected my drives fine. Attached the bad drive. It didn't find it. UEFI didn't see it either. The drive made about 5 repeated noises that sounded like head seeking on power up.

It does continue to spin or it does spin down ? Can you ear scratching noises or noises of the head stack hitting the limiter ?

Time for TTL log ....

I think it continues to spin but I will check again. No scratching or clicking noises. The only unusual sound is the soft buzz of the head seeking a few times. Will hook up a ttl cable. Do I need to enter any commands for initial look or just capture what it sends out?

Just capture ... DO NOT ISSUE any commands .... Plug the drive to TTL, open your terminal software and power up the drive when the software is already running ! Post the log.

BAD HEAD(s),

The head stack have to be replaced inside a HEPA 100 clean room.

Not DO-IT-YOURSELF. It's game over for "home" attempts.

This is the type of "recovery" that will cost you $600 or more on a professional data recovery lab.

And of course assuming that the platter is not damaged (and those drives suffer from media damage quite often) ...

Sorry, on this case there is nothing more to be done at home to recover the data.

If you do need to get the data back only option is to send the drive to a specialized data recovery firm or place the drive in a safe place in case you decide in the future to send it in for recovery.

DO NOT OPEN THE DRIVE LID yourself.

Also you are on the USA so you can try to contact member drHDD - memberlist.php?mode=viewprofile&u=31114 - and see how much $$$ he would charge for your case. I'm saying this because on the past he did some head swaps at a very cheap price, so you might be lucky but the main problem would be the fact that your drive is a DM series of Seagate that quite often have severe media damage that can't be rcovered and even when it can be recovered it can take several head stacks to recover, not just one ...

Regarding your message on terminal assuming that the PCB is NATIVE then the Heads can't find the servo markings on the platters and that is why you do get the :

FAIL Servo Op=0100 Resp=0007
ResponseFrame EE80 0074 06CC 3D00 (...)

...

Assuming the PCB is ok (probably is OK on this model) then the head stack have to be replaced FOR SURE,

This problem is 99% of times related to BAD HEADs / pre-amp (on the head stack inside the drive).

Regards and good luck.
