Hi,
I prefer it showing up as a hard drive..... Personally, I never liked how the synching process took over with my Gigabeat S60..... I did the same on my son's F40....
I like to have manual control over what gets copied onto the player.... Then just update the database inside Rockbox....
Also Now I can use the S60 & F40 as an external hard drive which greatly expands their general usefulness.....
Just my 2 cents...
