Hi all!

I have a Seagate ST1000LM024 type 1 TB SATA hard drive.
It is in a MAXELL portable hard drive chase.

Some days ago when it was in use accidentaly dropped from 15 centimeters to the hard floor.
The USB connection lost. Next time i try to connect with USB the win7 not recognize the drive.
I get out from the chase and try to put the PC directly using the SATA connection but the BIOS seems to be not detect the drive. It is spin up every time without bad noise or any suspicous sound.

I buy an another hard drive with same PCB what is works well.

What do you thing it is enough to change the PCB or need to do any other thing (change BIOS chip etc. ) to get data back from the old hdd?

Thank you for your help and sure I missing some information so please ask me if anything not clear


Thanks

Zoltan

PCB replacement will probably not fix your problem.
Don't do it yourself and find pro datarecovery service near you, if data are valuable for you

What do you think what is the problem?

Just think about it: could the PCB, whose main material is plastic overall, sustain significant damage from a 15cm drop? I think no.

Matter of fact, to convince yourself, remove the PCB from the donor working drive you just bought and drop the PCB (not the drive itself) onto the floor in a way that would replicate the fall of the bad drive. Does anything get damaged on the donor PCB? I think no.

It is likely internal mechanical damage inside the drive. Should no longer power the bad drive on and have a specialist take a look at it.

Yeah maybe you are right.
I just think the mechanical parts are OK bevause the disks are spinning and no bad noise.
There is a way to determinate the defect area more precisiosly?

it is more than 1000usd to recover a HDD in a clean room and simply I have no enough money

Maybe, maybe not. All depends on the failure circumstances.

If hiring a specialist, ensure they specialize in data recovery.

From your location I guess you're in Hungary?

If so, I suggest you contact member "Pepe" who is also in HG

Hi Cirip!

I your case most probably little media damages that affect to FW, maybe heads problems too or maybe very bad media damages too.

if only little media damage maybe cheam, but is necesary to get the drive and examinate on a clean room enbiroment.
