I'm having an older MaxLine III SATA drive here (7V300F0, JFTR), which does not contain world's most important data, but WTH, it works 100%, it just needs a kludgy self-made connector thing to "bypass" the broken-off cheap plastic top pieces that hold the connector in place. But as kludges are known for, they are always perfect sources of instability and data inaccuracy, too.

Look, I CAN solder. But only up to a certain extent. There can be cases where it's simply nonsensical to do such attempt (as here as well).

I got pretty surprised when I heard that a totally unrelated drive, the 6V200E0 uses the VERY SAME board as my drive:



( cf. http://pcb-hdd.com/6v200e0-va111630-302 ... p-945.html )

Now to my actual question:
My EAN (barcode) says


whereas the EAN on the replacement PCB says


I'm asking especially because of the R6GVC / R6GVA difference.
What do these codes stand for?

I mean, the PCB ID is still the very same, although these are fairly different drives. (Rule of Thumb: 6..... = DiamondMax series, 7..... MaxLine series).
