Doing a headstack replacement - help with post-diagnosis!

I had a Fujitsu mhv2080bh that suffered a fall in a macbook pro laptop. These laptops have the sudden motion sensor which is supposed to withdraw the drive heads to prevent problems but after the fall the hard drive just thunked/sproinged and didn't boot or appear as a drive when booting off cd.

So I decided to have some fun and attempt a headstack replacement. Ordered some mhv2080bh's and replaced the head stack. Now what seems to happen is the heads scoot over to centre sit and then back to the edge and then back to centre etc. etc. Obviously still not booting or being recognised.

What is this a symptom of? Can anyone point me in the right direction? The software options on the mac seem to be very limited and I haven't found the equivalent of mhdd or such.

Any help very much appreciated!

were the donor drives the same FW ver?

To be honest I didn't check (although I read that on these boards). How can I tell? The firmware isn't printed on the label is it? I suppose you can tell with MHDD or something like that? My problem there is that I'm trying to do this on a mac Sad Disk Recovery II doesn't see the drive and as far as I could tell that's about the only software out there for mac and it's not very low level at all.

Yes, it's on the label.

Can't remember where though. As far as I remember it's usually an longish number with loads of zeros in it.

You in UK?

Hi again pcimage and thanks for the help!

on the lable I've got Model, Part no, Serial no, Date, Rev. no and then OFFDIA-0081002D. Could that last bit be it? The donor drive has OFFE1E-00000028.

Yup in the UK!
