What are the chances for this to work? Head and PCB swap
Posted 15 July 2010 - 04:51 AM
I have got this hard drive which is not seen by the computer.
I have found this drive one ebay
What do you say?
Before I order this drive, is it can work for PCB swap and/or Head swap?

(No offence, btw)
- First of all you want to swap the PCB of a 120GB drive with one of
a 80GB drive
Maybe in that you *might* be able to succeed, but unlike Seagate drives
Western Digital drives store their drive-specific data (calibration data,
head-alignments, etc.) on an (EE)PROM on the PCB and not on the platters,
so you'll have to solder that (SMD) component over as well.
- Second: because of the size (and therefor the platter-) differences,
the heads of both drives will be different.
If I recall correctly: in a prior thread, you were advised by someone to
practice first with a working, non crucial, drive; opening its case in a
clean (-ish) room, removing the heads and replacing them again, to see if
the drive still works after re-assembly.
When you've succeeded, practice over and over again a couple of times before
actually trying to perform the operation on a drive that needs data recovery.
And only try it with parts you know are compatible; it's for a reason data-
recovery services have cabinets full of different donor-drives to temporary
swap parts with.
I can only emphasize this again: harddrives ARE NOT crystal radio-sets that
can suffer a bit of rough handling, but highly sensitive and complex devices.
...although: I do appreciate your persistence

@CrazyDoctor, you have already been told WHAT to look for to determine if a drive is compatible and WHERE to find the info.
You have also been already told how switching a PCB should be done AND the procedure that is needed (soldering/desoldering, etc.).
You have also been told that a Head swap is NOT something within your capabilities (yet).
You cannot ask the same questions, every time you get a new dead hard disk, comeon...
If the question is to be intended literally:
What do you say?
The answer is NO, and additionally even if the PCB was compatible, I seriously doubt you would be able to do a proper PCB swap, and I am pretty sure you would be able to do a head swap.
