Same thoughts - my V series died a few years back but that updater EXE in the other thread always worked when I needed to re-do the setup on the hard drive. Granted, I always used 32-bit XP or Win7 when doing that.
Rockbox itself never worked on the V series, at least not that I know of. Of course I had attempted that years back, including pulling a drive that I know had the correct setup but the S/V, although similar, are not the same.
