Dear colleagues, we present you our latest product:

Platter Stand

Image

HddSurgeryTM Platter Stand Tool is designed to enable the data recovery specialist to safely store and inspect the platters from 3.5'' drives, while they are removed from the hard drive assembly. This tool represents our company's further effort to enhance every aspect of the job a data recovery expert performs on a daily basis.

The tool comes in a form of a modular multi-part platter-carrying subassemblies, mounted on a single base and connected among themselves using precisely machined joints. Every part is made of stainless steel, making the assembly suitable to store the platters without compromising the security of their delicate ferromagnetic coated layers.

For additional info, take a look at PDF Manual and Video Guide on our website.

I think the question on everyone's mind looking at this tool is: What about platter alignment?

I know that modern drives write servo on each platter surface, but it's my experience that they are still extremely sensitive to any loss of alignment. I'd personally never remove multi-platter stacks like this, even if I thought it had a chance to work. Don't get me wrong, I'd love to be able to do a better inspection of platter surfaces before spending $300 on a rare donor, but I can't see this as a viable option either.

I confess my ignorance. Why should there be any alignment issue with an embedded servo?

AISI, if the relative rotational position (disc-to-disc skew) is disturbed, then the platter merely needs to rotate a little more in order to compensate for the difference.

Is this "alignment" referring to eccentricity? If the platter is a little off-centre, then perhaps its "wobble" could fall outside the range of the servo.

BTW, I do understand that there is an alignment issue -- I just don't understand why.

I agree fully that it shouldn't matter. But, for whatever reason if you rotate a platter even a little they tend to stop working. Maybe it's caused by something else, but I still never remove platters one at a time.

The Platter Stand is a support tool, developed after numerous request from our clients. To use it, a certain level of experience and knowledge is needed. If you have ever cleaned the platters of the drive struck by the floods, unskilled/sloppy data recovery technician or client, this tool would be very useful in terms of:

1. Having an easy approach to the platters

2. Avoiding problems with other platters while inspecting one

3. Easily sinking the platter into the cleaning liquid etc. etc.

We have made a simple and safe holder for the platters. It is up to data recovery engineer how to manage the platters and how many of them. We were asked by experienced data recovery engineers to develop such tool and so far we receive nothing but positive impressions.

We encourage the users to continue ‘’playing’’ :)

Well,
I am with you on this one but this is what nikola is saying .BTW nikola i do not use any of your tools til today ,Might be some day i will once we in india start getting good payment for DR work in respected to americans and european DR firms .Anyway i will share my viewpoit cos i said the same to you in a facebok or youtube post

Reply : Totally Useless Idea in my opinion ,You will need a big dia utensil/cleaner and it will need to be deep ,Were as single platter and muti platter stacks can be cleaned [ Properly ] With a 2 Inch Deep Cleaner/Utensil Just at the size of the hdd 3.5" or 2.5" when hdd it vertical standing " .Plus no issue wth mutiplatter adjustment .For inspection well for single platter there are simpler ways to do it and for multiplatter makes zero sense if we cannot reassemble to make it work again .

PS : my opinions are based on the fact of my knowledge and daily working with physical work in my lab .If someone wants to pour in better views of multiplatter alignment i would be grateful .Cheers nikola keep making new tools

I have nothing to add regarding the tool; I just want to congratulate Amarbir for his greatly improved English and typing. Well done, Amarbir!

If you have so many questions this is for sure not a tool for you. As i told you before , we are here to make support tools for our collages. We do not explain data recovery tehniques. For many reasons, fist and biggest one is we do not have enough man power.
I tried to explain all this on FB but as I remeber you did not want to hear me.
You want to explain your self things you do not know using info you have in your domain. It is impossible . You can not look over horisont , you must try to climb more. At least to try...

There are fixtures and methods to ensure platters are aligned and in proper position when re-assembling. Both virtually (after spin-stand read) and physically when putting the drive back together after a cleaning.

There are also ways to inspect the inner surfaces of the platters while they're still on the spindle.

@Keatah, I'm sure many of us would be interested in learning more about how this is done. I assume it requires production-grade equipment that very few of us could possibly afford. Any links?

I am not sure that it links exists, but it is not a topic here. We made a platter stand. Nothing more nothing less.
We know it will be use full. People asked for it.
