Ok first stop using seagate software to do your partitioning.
just boot again to the XP cd (does the dc already have service pack 2?) use xp to delete all partitions on new drive. then create 1 new partition of what ever size you like load onto that partion. once windows is loaded create the additional partitions to what ever size you like inside of disk management in windows. as far as the copy errors that is most of the time some sort of cd problem either drive or disk.
