If you are having sync problems with 100gb drives, I doubt that prior music is the cause of your problem. Zeroing out the drive will erase past music, but I think you've got a larger problem stemming from the drives being "large drives" and not having been built properly.

I suggest going over to riocar.org, hitting Disk Upgrade Guide, and using the builder images linked from there. Go through that whole thing carefully, paying particular attention to any section that says SPECIAL NOTE FOR LARGE DRIVES or similar.

I recommend running Mark's bigdisk builder twice: Once with only the primary drive plugged in, and once with only the secondary drive plugged in (with its jumper removed). Each time, also do as the disk upgrade guide suggests, and install the bigdisk version of the player software onto each drive as well.

If you get errors during this process, then you might be having data errors with the disks, possibly caused by cable/IDE header troubles. Investigate that, too.
