Comment 102 for bug 599255

# fdisk -lu (all 4 disks have exactly the same sizes)
Disk /dev/sda: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

I could not find a way to get the sector count for the array in windows...

Additionally, if it helps, RAID option ROM reports the CHS as 65535/255/63, but I doubt the values are correct.
Capacity for the whole array should be 7 999 999 967 232 bytes, and 2 000 331 825 152 bytes for each LD.
