so u added spinpoint as second (non-boot) drive to machine??? have you partitioned or formated it? They dont come partitioned or preformated... but it should have a drive letter until you partition it...
What type of format is on second drive verses boot drive there are some combinations that dont work well together... I would try reformating spinpoint to same type of format as boot drive for consistancy... External drive format shouldnt matter
NTFS, FAT16, FAT32, exFat and someother less common ones... the within formats you can have different cluster sizes as well... I would double check your formating. If boot drive is NTFS then if second drive is NTFS or FAT16 shoudl be a problem, but if its exFAT or FAT32 depending on the cluster size that might be your problem.
