I, and of course you can disagree, would not waste time or resources on these units.
ask yourself the following questions;

- How many of these units will be produced worldwide?
- How many units per month can you get to your company?
- Of those who arrive, how much will recovery cost and how many will they accept?

It is more interesting to invest time and money in other places, you are an example, there are not many who can work with SandForce (I can not and I would like) and that if you have more market

Maybe there is still some ways to unlock the drive ... I will have to test it out ....

But yes, if the goal is to do head swap on HE drives .... it will be expensive as when opened the drive will be gone .... so waste of $$$

1. You don't need 10 drives to learn how to recover them . You need only one , second hand and having bad sectors, i.e. cheap. You may read some documentation about the new command set as I did, but you are lazy . Oh sorry, you don't have time for this.
2. You ask the same amount of money (+500$) even in simple cases like burn TVS or dirty contact pads. Your excuse is that you'll cover your investment, but in fact this is an ugly robbery.... and you know it very well.
3. Another excuse - the family. But your victims also have families , don't they?



This is uncalled for.

You got a point about He drives, but it was just an example about how challenging DR could be.

What about new WD drives like Charger? Do you think you won't be seeing them soon for recovery?

every month we have a fixed budget for research (been increasing recently), and buying those new drives is one of them trying to be 10 steps ahead to understand things better later

Now that's exactly the reason DR is expensive.


Its not the DR, its the research & the results that costs specially when you get to know something new and nobody or FEW knows


Yep, this is what I mean.

I believe that the DR business will change, as will all the lines of business that depend on technology.

Mechanical hard drives have little life left, in DR we will still receive many drives for a few years, but I don't think many drives over 10 TB will arrive. Currently and in the short term, whoever buys these drives is basically for mass storage (cloud), with redundancy, so if they fail, they are replaced, they are not recovered, and they will not have time to reach the mass market because the solids in a few months will surpass the mechanical hard drives in capacity and cost per GB.

The reliability and recoverability of data after a failure? It doesn't matter, only the cost per GB and the transfer rates are important

The DR will be very different, many cases will be irrecoverable, there will be much more competition (infrastructure costs are lower, there is no need for clean rooms, many spare parts, combs, etc..) and here yes, the secrets, and therefore the research, will have much more value.

The main enemy of the DR business is called "backups" and the depletion of morons not backing up their important files....

I'm not forced to give the customer all these things for free.
Proper diagnosis worth money by itself.

I've got more then 20 years of experience. How about you?
Just another excuse for cheating....

I'm working as individual and I supposed your are working as individual too so, let's make it between you and me.
An example:
How much would you charge for: Dropped Shrek_LT 2 TB (4 platters and 8 heads) side 6 and 7 have serious scratches to platters. Donors risk is at me, and I have lost 2 donors now until I have imaged 88% of the drive until this moment and still try to image the rest. Working on that case since 30 July (6 days). If I didn't get the customer specific folders I won't charge anything from the customer (even for donors used)

Why do you even bother?
He claims he can fix a beeping drive by solving slow responding... :mrgreen:

Nothing ... since I'm not in the DR business. And yes, I have repaired or downsized several drives like this. And hundreds other drives as well.
I know that DR people are very scornful to HDD repair, but believe me, my knowledge is not less (or much less) then yours.

Stressful.
I'm waiting for you to post the vendor commands to unlock the WD Arch7 drives.

@Northwind
I don't know about you, but I fix the “slow responding” by changing the configuration module with a proper one. Maybe you are doing something else and for this reason my suggestion looked strange to you.

I didn't post any VSC's until now (I do know many, many) and I'm not going to post in the future.

You didn't answer my specific question?

I am not talking about refurbishing here.
Don't tell me that you never make a DR cases in all your 20 years of experience.

Well, I have done many DR cases in the years , but I have never asked more than 25-30$, believe me or not....
If the case is too difficult or time consuming I redirect the customer to a DR company.

I will believe you if it was a logical DR cases (related to FS, deleted filles...etc). And of course I won't believe you if it was physical cases.

For me DR is more like doing a favour, not a business. Somebody needs help and I help him to get his family pictures back, for example. Not a big deal. Only a person born and grown up in a socialist country could understand this....

May I ask, what's your main profession?
What I mean that you are not doing data recovery for bread and butter?
How could you survive all this years with 20-30$ maximum per case if this only your mainly profession?

I used to repair computer parts like mobos, video cards, monitors, hard drives, etc....I didn't rely on DR for bread and butter, only for peanuts...
