Seagate bearing failure survey

[jono-ats]

I'm currently working with a Seagate Barracuda 7200.10 (Tonka) drive with motor spindle bearing resistance.

I would like to remove the bearing cap and lubricate the motor, but on this model bearing cap that is recessed inside of the casting. It is like looking down inside of a small crater.

Has anyone drilled out this type of cap? If so, how? Or alternately, had success swapping platters and motors with the Salvation platter tool (on a Seagate Barracuda drive with two platters)?

I've got a dental appointment tomorrow and I'll see if he has any bright ideas. I'm desperate!

Thanks in advance.

Hi Jon, thanks for the Pcb Btw you have back soon
I've great success with my home made tool for free stucked motors and bent axxis.
The last one I had success with was an 500Gb Seagate with plastic airlock.

Have nice time with the dentist tomorrow

mr_spokk,
Hi,

Can you tell me the price of that tool for free stucked motors and bent axxis?
if you cant sell, pls tell me how to make one (you said it was Homemade).

Thanks,
RDS.

I had a tool custom made that was similar to the one that was shown, except that it used a standard "T" and was drilled for Maxtor, Seagate, & WDC.

I used it to free up the Seagate I had posted.

However, the bad bearing vibrated enough to keep the heads from reading . . .

I wonder how people deal with the collar that is between the platters? I can't figure out a way to do a head swap. I can't think of any good reason why Seagate might have added this part except to prevent platter swaps!

Hi Jon,
There is one more reason I'll guess: http://services.seagate.com/business_solutions.aspx
And thats probably a very big reason for them.... unfortunately

Of all drives I am receiving for recovery at the moment (large capacity, recent manufacture) I am seeing more Seagates than all other drives together.

I have been working on a solution for this with a CNC -capable toolmaker and we are meeting up on Thursday to discuss possibilities.

I have raised the issue with Seagate directly, as I believe it is a design flaw, but have yet to receive a response.

Two years ago Seagates were the best; now they are the worst.

I would not be inclined to purchase shares in their company at the moment....

I suspect It's NOT a design flaw (Flaw or feature: Open to interpretation). I find it very suspicious a number of things have happened around the same time:

Seagate bearings start going like crazy
Seagate adds a collar to prevent platter swap
Seagate opens up a Data Recovery service.

I really hope it's a coincidence, because that would be a really nasty thing to do.

I wouldn't be surprised if Seagate has also embedded special registration marks allowing them to line up platters, or perhaps they have a special Firmware that allows reading platters even if they aren't aligned.

I have tried the drilling method, i have got inside and put oil in there but the 'burr' is jammed so tight it does not move with oil added. In cases where i have had jammed motors, i cannot even move the motor manually with full force using plyers or other tools! It's just stuck solid!

Does your 't-bar' tool you created actually get the motor loose/free again?

I've had to do platter swaps out of desperation...no other quick fix found.

I tried it on only one drive and it worked.

How do you do a platter swap on a Seagate with the plastic ring?
