Check the cylinder/head/sector against the BIOS. If neccessary, you can use fdisk (or cfdisk) to force a change, but this will likely destroy any data on the disk. Also make sure both disks are partitioned identically - RAID1 will only be as big as the smallest of the partitions. It does look like fdisk has picked up the wrong CHS numbers - the disk only appears to be 127GB is size according to those. (255*63*16709*512)/(1024*1024*1024) = 127.
