Isn't it mis-leading? how is it possible?

August 12th, 2016, 8:32

One of my client gave me this link about stellar data recovery.
https://m.youtube.com/watch?v=ooBGG7RoSOc

At the end of the video, they show they have thousands of heads residing on table. Those are used as donor. And my client said, I'm wrong we don't need donor hdd. Stellar has stock of donor heads instead of full hdd.
What do you think of this one? According to my understanding, those are the already used donor heads that were arranged on the table

Well, if someone is organized enough to have heads already removed from a drive, labeled and stored in a safe place, it should work. It certainly would occupy less space and speed up the transplant process.

Do you really think its organized donor heads? Suppose they need a head from the middle of the table then how do they pick up this one without destroying others?

They may have a database with a reference number correspondent and attached to each head stack (which contains the information of the drive they came out of - lots of work upfront, but less later in theory).
Some techniques shown are qu______able.


Needless to say, good for advertising.

The first thing I noticed is that they powered up a hard drive that had been dropped.

Best practices dictates that the drive must be opened and thoroughly inspected first, or the damage can increase.

We sometimes store heads outside of the drives. The heads are usually separated by combs; the head is boxed in a transparent enclosure and labeled.

We have junk heads arranged like the ones shown on their table.

Everyone does things differently. :-)

they are using Screw Drive to MOve Heads check end of the VIdeo :shock: :shock: :shock: :shock:

Just another BS promotional video. Air-bath entrance yet carries in a cardboard box that no doubt spews particulate/fibers, no cloves while they work on the drive, and oops! ... dragged the heads over the platter at the end. Most end-users would be impressed. :roll:

If that pile of heads laid out on the table is really the ones they are using, I'd guess their success rate sucks pretty bad. For one, there's no clear labeling of where they came from so they'd only be guessing at which ones are which based on their appearance??? Also at the end of the segment when they are talking nice and loud right over the whole table with no dust masks on, I'm pretty sure they contaminated all of them with spittle. I'd guess those are just old heads they laid out for appearances. Usually, I try to keep the old heads and put them back into the patient drive after I'm done imaging, but I've still got a box of old ruined sets of heads laying around.

Heads already has labels from which model are they. Why anyone needs to mark them additionally?

How about the part number, DCM code, DOM, first three of serial, site code, preamp vendor / rev, etc.? There's a whole lot more to finding a set of heads that actually work than just model number or the fact it's the right head map & fits. Just this weekend while doing an emergency project I had to swap heads three times before I found one set that worked. All from the same model WD drive all built around the same time and nearly identical in every way.

I suppose they could be scanning in the barcodes of each set of heads and putting the rest of the necessary data into a database. Just seems like an awful amount of work to go through.

Also, if they leave them out on the table like this all the time, they'd need to run their clean room filters 24/7 to protect them. If their HEPA filters cost the same $400/ea that mine do, I highly doubt they are doing that. Plus there are clear advantages to keeping the heads in their original drive for storage, like the fact that you can pre-test them before each use to be sure they are good. That way you avoid unnecessary extra head swaps which could be causing damage.

Look like all this stuff (the part number, DCM code, DOM, first three of serial, site code, preamp vendor / rev, etc. ) didn't help you, ah?

I had to work with only the drives I had in stock as an entire retail store was shut down until I finished. They couldn't even process any payments because their entire POS server was on this one drive. So I picked the three closest matches I had and gave them a go. Had the store back up and running by the end of the day. None of them were what I'd normally have purchased as donors, but all were the same model.

1. Those two are the most annoying people I have ever watched on YouTube.
2. Professionals use professional tools and all I see is Chinese garbage.
3. You never power on a dropped drive without checking it internally. Data recovery 101.
4. I would carry it in a anti static bag rather than a dumpy dirty box.
5. The guy is worried about keeping the drive safe but stacks running drives over a foot tall with used CD spindle boxes next to walking areas. Crazy!
6. They encrypt all your data. How wonderful!
7. They go through all the steps to enter the nice clean room but bring in a dirty box. Weird!
8. I don't buy the entire table devoted to working head stacks. Seems like they stuck dead heads on a table to look good on video.
9. Bare hands. Weird!
10. A professional business doesn't use paper to separate heads.
11. I don't see any anti-static tools.

So you didn't care about all this stuff and got result after 3 attempts? Same as it could have all credential the same and you still need to check some heads before working one, right?
