Hitachi PCB Problem

October 29, 2012

My hitachi s/n: HQ0X920H, is not recognisable by the pc, even if using the usb/ide/sata adapter. When plugging it, it makes some sound, like trying to w/r ant the head knock against something.

Is this a problem of the PCB, if yes do you have it and how much it kan

The PCB can spin but can’t be recognized. In most cases, the problem is not cuased by PCB.
Replacement the PCB will not solve the problem below.
    * The drive will power up normally (no ticking noises, errors etc) but will not be recognized by the computer
    * The drive will power up normally and be recognized correctly but will report a size of 0 bytes
    * The drive will power up but report SMART errors on boot
Those problem is caused by the HDD firmware corrupted.

I do have another case; a 3.5" sata hdd is making a ticking noise, like it tries to read and fails and you hear a tick, like if the laser head is punshing against something.

Is this situation a pcb problem? and if yes do you have this for me and how much it will cost?

If not what kind of other choices I do have to have this HDD data recovered? And how much it will cost if only recovering data?

The model number of this HDD is hitachi, seria number is hq0x90h.

For the first HDD you send me replay about it? Can you flash the suitable firmware in it? And how much it costs?
