Have a 7200.10 drive. Came from a Dell with a dead MB. Drive powered up once out of the machine, but now it is dead. Won't power on. Data is worth the effort.

PCB swap from PCB Solutions web site? Do I need a chip swap as well?

Model: ST3320620AS
P/N: 9BJ14G-033
Firmware: 3.ADG
Site Code: WU
Capacity: 320GB
Main Chip #: 100404225

Post a pic of the PCB, component side up.

It seems that the board it's a little brown.
Post a picture of the other side.

If the HDD won't even spin up then you can try testing the 2 components in red here:

If they measure 0 ohms or very close to it then you can try and remove them and try and power up the HDD. Use side cutters or a heat gun to remove them. The HDD has no power protection once they are removed.
There are obviously risks involved.
Search for 'TVS' in this forum for more info on it. If that doesn't work then something more important on the PCB is fried, like the MCU or something else.

The serial flash memory IC is the 8-pin chip (Atmel) in the bottom right corner of your photo. It should have a "25" in its part number.

TVS is a hard term to search for. Can you expand on that term?

One of these has 65Kohms, the other is cooked I think at 1.9ohms. I'm using an external drive caddy to test this disk. When I apply power the power LED on the drive caddy immediately goes out. I'm worried this drive has a short somewhere.....

I have another 7200.10 320G drive that works slightly, but doesn't model/date code. Can I at least use that PCB to test this drive and see if it will spin up? Or is that a bad idea.....
