I have two Toshiba HDD's-- everything is the exact same, ie, CYL16383, H16, S63
500GB-LBA 976,773,168 Sectors on both of them././.

My Question is:
The voltage on the old HD is +5 VDC /1.1Amp
The voltage on the new HD is +5VDC and 1.0Amp

The actuator has failed on the old HDD and it took .1 Amp more in power to operate..

Will this be a failure from the start if I do this swap???

Why on Earth are you swapping platters?

Sorry to say, this is a DIY disaster waiting to happen

I have done several over the years. Fortunately, I have always located and exact match. This biggest thing is .. take your time, use gorilla tape to press yo the sides of there is more than one platter.. you can make some very nifty tools to keep head separation.. it's not to bad.. I have had some fails along the way. P

If the "actuator" failed, then why are you swapping the platters rather than the actuator?

I am pretty sure it's all non recoverable. It was dropped from about 15' in the air. HD had a pretty good dent on the out side.. Pretty sure I sure I had multiple issues with this HD
Because of the impact.. Just ruling it out. When the hard drive was dropped a tiny pin broke that supports the magnets position.

Exactly so!
