Running the big disk builder after the regular builder does in fact work. However, it may not work very well.

I thought everything was well after doing the wipe > big disk builder 6 > mkIIA 2.01 software w/hijack. Unfortunately, my first sync had an error at the very end. (after 3 days of syncing)

"Synchronize failed while writing player configuration. An operation was attempted on something that is no a socket. (error 0x80072736)"

The player is displaying this: 0000.0 segfault err

I only uploaded 180GB of music to the player, and there is 110GB free still. What could be the issue?

I used ethernet, and also a direct connection with the computer rather than going through a switch.
