Well,
Platters can be taken out all together and even one by one without loosing platter alignment and also inspection can be done .A custom tool can separate platters ,help you in visual inspection and reassemble them back so they work ,but the story changes when it has passed via a lab with lousy techs i recently got a seagate case were top platter was scratched when top head was not ever present in headstack lol

Did you manage to image it and recover successfully bro? What is the process that happens after the imaging process in detail? thanks!

after a successful imaging, is there a chance that the data is unreadable due to system area damage? Are there any algorithms or software that can decipher it?

without system area access it is not possible to read a single sector from the drive, so it is the very first step to gain access to important SA objects.

Encryption on the desktop internal HDD is enough rare situation (if we are not talking about malware). If your drive has been imaged successfully, so what is the problem to get access the data?

Do you mean that even after imaging 100%, without SA, you are still unable to access data? How do you gain access then? Thanks bro

perhaps they used RAW rec, which is crap on Ext fs unless written smart. Just an idea how it can be truncated...
btw, it is not appropriate to say the drive imaged 100% when it's not. If they cloned 95% but the FS metadata is in the remaining 5% it can bring up some problems.

An hot swap would be completly out of the question


hotswap is not out of question, but probably not the case here.

i just meant it can be done. But i don't think the actual recovery has gone this far.

Well,
For These DM series i have given up .Mostly they end with bad platter surface and scored media .As fas as hot swap is concerned ,We can take a donor after we initialise it using translator etc from other patient .Then make it standby swap donor heads to patient and voila .But who goes this farrrrrrrr offffffff

what are some of the software available out there to translate the data? Will it be successful?

really sorry to bring my thread up again as I have been banned previously for asking regarding this issue. I am not a tech person and just want my data back. I am confused at what is happening and am trying to seek help here from you seniors.

The DR firm managed to image my drive but the result is in raw data form and is not readable as the files are all messed up. They said they are unable to read the data properly. Is there any recommendations anyone can make? Thank you once again for any advice.

Re: Small scratch on edge of platter - is it over?

Eh, it seems i was on the spot then with the RAW recovery idea....

I think there is no more recommendations we can give unless sending the bad drive and the image for further investigation.

Dear Pepe, do you mean your reply on 9th May? This one

yes, i meant that but as you told me it wasn't Ext but NTFS, it puts things in a different perspective.

Re: Small scratch on edge of platter - is it over?

I could look your drive, if you can send it to me.

Re: Small scratch on edge of platter - is it over?

yes I have pm-ed him, thanks for the suggestions! Would it be possible to recover from a scratched platter? is getting the drive to image the hardest part?

Re: Small scratch on edge of platter - is it over?

July 8th, 2017, 9:32

It is not possible to say yes or no responsibly without evaluating the damage. What's not possible for one company might be possible for another... I also recovered many drives others refused or failed. Economical questions also arise sometimes.

I sense that the OP is not interested in your offer, @drHDD. He just keeps posting more questions on Toms Hardware - http://www.tomshardware.com/answers/id- ... l#19921551

It is starting again to look as if the question is not real.
