Need some help with this one, PLEASEEE ...
DM series are a nightmare and I'm not used to this type of drives at all.

Problematic drive is the one displayed on the photo :



Heads were determined to be BAD and HEAD STACK was replaced inside hepa 100 laminar flow workbench.

With the new heads drive just stay BSY on PC-3000 UDMA and on terminal the following message is displayed :



With the PreAmpFaultStatus message my guess would go for a damaged Pre-Amp during the head stack replacement so the heads were placed back on the donnor drive and THEY STILL WORK JUST FINE. In other words heads/pre-amp are still perfectly OK when swapped back to donnor, but on patient the PreAmp fault is displayed on Terminal/PC-3000.

Legal PC-3000 UDMA is available for this task.

I don't think that this is adaptive/Rom related so I'm guessing that the pre-amp is just not compatible with the ROM of the patient drive.

Can someone confirm this and help out with criteria to select compatible heads/pre-amp ?

Or would this message indicate some firmware damage or othr sort of damage ? No platter damage can be "seen" by visual inspection of the platters.

Thanks.

Did you match first 3 of serial number, full model, part number and site? I find if all match, so do heads.

What happens if you put the patient PCB onto the working donor?

Click? Spin down?

Post terminal response for this.

Hi and thank you all for the reply.

Donor drive only match by Model. Serial and Part number are completly different.

This is the donor :



So by now i'm positive that the heads (pre-amp) are incomaptible.

Next step will be to either match the first 3 of serial number, full model, part number and site or even better if possible to match the first 4 of the serial ....

I will let you know later when new donor arrives.

Regards.

Correction on the above post.
Part number and model are the same. Serial number are NOT.
Damaged drive starts by Z1 and donor by S1.
Guess that the trick will be to get a "Z1E0" drive (serial).

yeah S1E is not a good donor for a swap dude. Z1E should work. I find there drives are some of the best Seagate made for headswaps.

The first letter of the S/N indicates the country of manufacture, the 2nd and the 3rd are important if possible the 4th, i always check under the microscope to see if the heads have the same shape/pattern.

I am stucking with the same issue here.

Patient :
Model : ST2000DM001
FW : CC4G
Site : TK
SN : Z1E

Donor :
Model : ST2000DM001
FW : CC25
Site : WU
SN : W4Z

After heads replacement the patient still clicking. When heads back to donor it works perfectly with no delay sectors.

Still looking for fully matched donor.

Good luck

So, the only thing that matches is the model number? Good luck with that.

what is the criteria to assume above disk are compatible for head swap?
just model number, i wish Seagate produce such drives to minimize expensive donor costs and making data recovery easy and affordable.

I have no choice this is the only DM drive ( Grenada ) I have. It was just a try.

As I mentioned I am still looking for a fully matched donor.
Thanks for wish me luck.

If you had to travel from Europe to America but you wouldn't have the choice to board a plane or a ship, would you swim?
You could try, but it will not work!
