@Nox1911:
Hey, you really shouldn't have opened up that drive mechanism if you're still hoping to read the data off it!
Those units are hermetically sealed to keep them free of contaminants.
The gap between the heads and platters is typically so small that a single particle of dust or even cigarette smoke can cause damage if it gets between them...
So get it sealed up again quick and hope that no harm has been done while you've had it apart.
You're best hope is that, being an old drive, it's not made to the same exacting tolerances as modern drives...
Those illustrations you see of disk internals in magazine advertisements are just to make them more interesting to the eye... They're not meant as an invitation to actually open them up!
What next, I wonder...
