I swapped 2 platters on 80GB Hitachi Travelstar (without platters tool) and want to know if it is possible to
synchronize or make to work again because bios doesn't detect the drive, I want to get the drive working again !
!!! THANKS !!!

I think this one is for the bin; no hope whatsoever.
Sorry, this site is full of warnings not to swap platters; somehow people think that is THE solution.

Sorry for your data.

Is this your personal hard drive?

I don't want the data I want to get the drive work !

And my problem was : "first done and then reading manuals and warnings"
My fault and now want to know if it's possible to get working again ?

No, bin it.

I probably have a solution but :

1) involves using of a >5'000 EUR instrument
2) if the skewing is more than expected it would be almost impossible to fix
3) the platters and he rest are surely contaminated
4) it takes time
5) a new drive is less than 50 EUR.

...sorry

Agreed, I know the manufacturer can potentially realign the platters. I had a Seagate .10 in that took a nasty shock and had misaligned platters. I contacted Seagate, there recovery costs for something like this are £3500+

Can I ask a related question

How do the manufacturers initialize (aka 'low level format') the platters on newly assembled frsh drives ?
Do these use soem other manufacturing electrics to drive the motors and heads and write the tracks and sync info etc
Or do they use the standard electronics and some low level init commands

Since they would want to do it as fast as possible, I guess they have some special production line electronics to do it (which then updates the p-list and alignment info in the SA)

@Xsoliman : google "SERVO TRACK WRITING" : specialised equipment from several hundred thousand $ to million $ are used and there are other production steps involved but these are proprietary info.
Until a certain extent is possible to recert the drive but it is usually a destructive process for the data (fix the drive but you'll loose everything on the disk).

About the misalignment, is possible to fix and the $3500 quote was appropriate for that case IMO.
