Hello all,

First of all, sorry for posting a question on my first participation here in HDDGURU.

I have a Samsung drive (External) with stiction issue (head stuck to platter), but as the head was parked at the end of the disk then I easily took it to parking place without any damage to platters.

The problem now is that after plugging my disk on PC I started copying all data from the disk to my PC but in some cases the transfer speed started dropping to 0 kb/s, so I tried to open the drive again and clean the top platter with a microfiber cloth, very smooth. So after that my drive stopped being recognized in any PC. it just recognize the Hardware but no disk unit is mounted in Windows.

Does anyone know if I damaged the head or entire drive doing that?

As the data inside the disk is really important to me, I was thinking about to try to clean the head using a spray of compressed air or isopropyl alcohol, is it worth?

Thanks in advance,

i cant see up to brazil


i think DIY is over send it to a pro, after the damage is done maybe, just Maybe is still recoverable and who knows how much $$$ is gonna cost

...

Then you shouldn't have done any of the things you did



Just because you can't see the scratch doesn't mean you didn't scratch it



Destroying what was left of your data in the process.



Makes no difference now, your data is gone.

The time to ask these types of questions is before you start, not after you finish destroying the drive.



You're welcome!

First, thanks for all your points and I do know that I made mistakes.

Sorry for bothering you but please can you tell me why I lost data when I cleaned up the platter? Couldn't be just the dirty disk's head?

Dude I'm sorry but the data is important to you and you try to clean the platter with a microfiber ? oh my god.


algorithm to solve your issue:

Disk damaged ?

No ? -> Backup anyway.

Yes ? - > Data is important ? Send to a PRO.

No ? -> Try cleaning the top platter with a microfiber.


You've just made a probably easy recover turn into a 1k+$ job... (tbh i believe your data is gone because you lost head/platter position)

Thing is we don't know the exact mode of failure. But I do know that rubbing the surface with. A cloth isn't kosher.

Sorry to hijack the thread (as the data is now destroyed anyway), but I would be interested to know why the heads sometimes end up on the platters inside of making it back to the parking ramp.

I had assumed that even in the event of power loss, the back-EMF from the spindle motor could be used to retract the heads to a safe parking position. Does this sometimes not work as it should, or is it due mechanical shock or a drop to the drive which causes the heads to move off the ramp?

In my case it happened due to a drop to the drive.

Well,
Have you started doing DATA RECOVERY now ? .

At least I tried, I sent it to analysis to a company here in Brazil and they want to charge me in R$ 2,500.00 (Almost U$800) to try to recover some data.
This is not an affordable price to recover the data, I know that I have some important things on it but I will try to recover by myself.
I bought another external drive (same brand, model, revision and fw) on eBay and I will try to replace the disk head as my last shot. (I am reading the best way to proceed to transplant, considering the lack of tools and knowledge )

Anyway, thanks all for every information shared.

dont kill another working hard drive. it is time to cut your losses

Well,
No one can stop the terminator

These questions and answers are priceless. Curiosity killed the cat.... the hard drive actually.

Eveybody is a data recovery guy it seems
