ST3000DM001 - Completely Dead

[data-medics]

Looks like the heads missed the ramp which is actually a good way for them to fail as long as they got stuck there and didn't pass back over the platters (I assume it wasn't loudly clicking???).

The drive should have a good chance of recovery, but it'll likely take 3 or 4 tries before you can find a set of donor heads that actually work. These DM's are a nightmare and often don't work even with a perfectly matched set.

You may want to even try transplanting the magnet set over too. It rarely ever makes a difference, but I've seen a few times where it helped. Given how twitchy these are, it's worth a shot.

Heads can't read servo labels. Drive will not start normally even if just one head can't see them. And there are six heads in total.

I also tested the hard drive by soldering donor and patient drive ROMs on donor PCB to check if it work or not.

Most appropriate test now would be to install donor heads back into the donor drive, it will give you the necessary answers.

Generally, I'd say that according to our experience and considering what happened / what has been done, extraction will require no less than a month, as I believe that situation is likely to be serious. I definitely wouldn't rule out physical surface damage and if so, then this drive requires a different approach.

P.S.
We are rather close to you and will be happy to help with complex recoveries like this, if necessary. Please check your PM.

Well this drive has a bug. It's called ST*000DM001.
Most probably you've done everything right but still...

I agree with Dmitri, install heads back to donor and see if they work. If they don't, either the head swap went wrong, or there is media damage on the drive.
In my experience, if there is media damage with the drive and your client is not willing to pay even for the cost of 4-5 donors, then you're wasting your time.

Hi zeydullak, when I said there is bug with these drives I meant that these drives themselves are problematic.

Good luck with your recovery.

DM001 "bug" = shit quality

zeydullak: What were the results?

[deftrue]

Have you been able to play with the ROM settings?

Thank you very much guys. DM series is a really big problem.

No joke. I've got one here that actually worked for 10 min after it's first headswap before beginning to click and spin down again. Really frustrating! Customer just paid for second donor, so we'll see how that one goes. The 3Tb model is the worst one IMHO.

I just tell my customers up front that these usually require 4-5 attempts before success, and that as long as they are willing to keep investing in parts I'll keep trying. And if my efforts eventually pay off, I make $800-$1200 for the labor. Though more often the customer backs out after the first or second set of heads crap out, and I just wasted my time.

whatttt ?

and I just wasted my time.

without getting paid a dime ? you are nuts ! sorry for the language

Did you get any servo errors after swapping the heads? That's what I'm getting with my 3 TB...
