I have a seagate momentus on my bench with a fairly unique symptom (For me anyway)
The terminal will show Head Mask 00, ** (** cycling through the retries)
The head varies between 00,04, and 05.
If I press Ctrl-o during startup I see an error that says "Spin Unstable"
If I run the report on firmware staus I get an error 11 (Spin Error)
The BSY register remains lit with no other activity

I humbly request responses from those who are obviously far more knowledgeable than me on Seagates for these few questions.
1. Is the reading of the spin speed done between every head check? Example:
Head Mask 00, 01
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AASpin Unstable
AASpin Unstable
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Spin Stablized
--- And then it repeats on the next retry
2. Would the combination of the Head mask retries and the error 11 point to a PCB problem?
3. Would inconsistent voltage cause the issue?
I am awaiting the donor now and will try flashing the rom and moving the board, but am I wasting my time and should just go for the heads?
Thanks for the time to read this post, I will append the complete terminal logs once I get back to the office tomorrow. Is there any other information you would like to see? BTW, it did switch to full init once(and DRD, DSC), but could not even begin imaging before it went back to the steady bsy.
Thanks
Shawn

Hello Shawn,

On the first look it sound like problem with the heads. But on a second look in particular with your spin unstable message and error(11), I would think that it may be a problem with the speed of the platter rotation. Although I am no guru and can't garantee 100% that this is your problem. I would definitley take a look at your motor controller.

... Or bearing.

Am I right in thinking that the head mask is the searching for servo tracks?

Hy phisin_ca if heads its trying search servor marks, u should be got AM recquired or AM , means Address Mark Recquired, would be interesting u could post u here the full log, u could tried to put here the "Age" and if show "Not Ready " or "Ready" By terminal commands

Regards

Beto, I have a meeting first thing this morning. I will have it after 12:00 EST Thanks
Shawn

Uh .. . Yes of course could also be bearing.

But hopefully not it's more difficult to fix.

Given I have never done a bearing on this drive, I would feel better sending it to someone who has. If it comes to that are there any volunteers on the East Coast that have good luck with them?

Hi ,
could You change the PCb Once and Try Out ,It Could Be That the Spindle Motor Is not Getting Proper Drive

Drives cannot stabilize spin speed without getting signal from heads. So if heads are bad, it is easily possible to get such results.

This is not always true, because the drive can stabilize the spinning form the measured current from the spindle's coils as well.
The most drives can reach the correct RPM without working preamp!

Janos

would be more usefull im think if u post here the full terminal log

Correct

Pepe Sir ,
you To Correct ,It Depends on Model

I would love to hear Doomer's oppinion.
According to my knowledge the coarse rpm setting is done using BEMF signal and fine tuning of the speed is achieved via the servo labels.

The fact that the Spin "recovers" and then the head mask pops up seems to support Pepe, but these are somewhat foreign to me.

I am still waiting on the donor to arrive. I will update the post withe the results once it does.

Sorry pepe, it really depends of the model
For example Maxtor N40P can stabilize RPM w/o signals from a head
But many other drives using servo for RPM stabilizing

The horror Noted... are all of the seagate 2.5s susceptible to media damage? I thought it was mostly isolated on some 3.??? firmware or apple drives. Not that I would ignore the possibility, more so just to continue the conversation.
