Fried PCB on a Maxtor 6y160M0

I lost a hard drive a couple years ago due to stupidity. It's a Maxtor DiamondMax Plus 9 SATA drive with the following numbers:
YAR51BWO
K,G,C,D
6Y160M004531A
R5FYA (F/W number I think)

I've done a lot of searching online and the closest thing I've found to solid information is this (from HDGuru Forums):

"For the following Maxtor hard drive models: Fireball 3, DiamondMax 16, DiamondMax Plus 8, DiamondMax Plus 9, Diamond Max 10 and all MaxLine products there is also a GTLA Number on the model (next to barcode on the bottom of the drive). Format 1Y222J2223322. 1, 2 and 3 stand for numbers, Y and J for letters.
The numbers 1 and 3 as well as the letter Y need to be identical to be able to replace the PCB on these drives.

This number can be found on the large sticker on the top of the drive.

Kind regards,

So in my searching I have NOT been able to locate a drive with the matching "33" number. Does anyone know if the firware number matters (R5FYA) or the "YAR" number (YAR51BWO)??

I've searched eBay (admittedly only at times) and a lot via Google. If anyone comes across this post and can direct me I'll be very very very happy and I'll even send you a reward.
