Replacing logic board soon, everything same except motor control chip

[franztoro]

Hello everyone.
Pretty much the title is self explanatory. I have a hitachi hard drive that doesn't even turn on so im praying that the logic board just died on me. I found the same logic board on ebay for the same hard drive. Everything is exactly the same including the main controller chip (same #). However, the motor driver chip is off by one number. Mine ends in 4 and the one I looked up on ebay ends in 5.

Do you guys think this will make a difference ?

Thank you.

Most important is the firmware rev. If they're both the same it shouldn't matter which chips are being used.

How do I verify the firmware version? Isnt the firmware encoded in the main controller chip (they are both identical)

if the drive is cheap enough, I would go ahead and try it...

if you do get the drive to function, then copy all important data from it ASAP...

It should be printed on the label or in the model number. Here's an entertaining guide:
