I have a 500Gb WD5000AAVS .Bought new 4 days ago.Moved 385Gb of data from my computer on this hdd which came as external usb drive,branded Comstar.Piece of crap!.Suddenly I couldn't access it any more.Bought another one WD5000AAVS-00ZTB0 and replaced the PCB.No luck,just clicking and stop spinning after 10 sec.Not detected.I opened the HDD and found on head missing.In order to swap the heads,should the plates be positioned exactly on the same position relative one of each other?If they rotate one of each other is any chance of recovering data?Can the plate be read individual or needs to be both and aligned like the original?I am not expert and any help will be greatly appreciate.

Hi,

I think, you have ruined allready all your chances...

Anyway, read this:

Bingo !

No hopes u kill the last chance like janos told u WD its very sensitive to alignments at all axis, when u take off , u lost that alignments, unfortunely

Or better... is still possible to get data (assuming no surface damage) and even fix the relative shifting of the platters. If you have something like 10-15'000 $...

No surface damage?
Without head?

Thank you all,this was fully understand.My bad luck.Now is there any chance- assuming i did not rewrite the HDD where I transfered the data from-that I can recover files bigger then 4Gb? R-studio and Stellar are seeing those files as 0kb instead of 5 or 6gb iso ,like the original were before formatting.The partition was NTFS and was formatted NTFS too.What I am doing wrong?Why I can recover 3,9GB and files bigger then 4 gb shows as 0kb?Is there more powerful recovery program for my previous HDD?

yes, there is.

In some DR company's lab.
Ask some, if you want your data back, before destroy the remaining parts....

how much will cost recovery of a 300GB hdd?

It depends on the company of course.
Usually i charge 160-300EUR for this. (Logical recovery ~300GB)
But i am far from you...
Ask your local options, i suggest....
..and don't use more the hdd until the recovery done!!!
