Disk geometry problem.

Hi all.

I have a CentOS server:
CentOS release 5.7 (Final)
2.6.18-274.3.1.el5 x86_64

I have two SSD disks attached:

hdparm -g /dev/sdc /dev/sdd

/dev/sdc:
 geometry      = 14593/255/63, sectors = 234441648, start = 0

/dev/sdd:
 geometry      = 14593/255/63, sectors = 234441648, start = 0

sfdisk shows:

sfdisk -g /dev/sdc;sfdisk -G /dev/sdc
/dev/sdc: 14593 cylinders, 255 heads, 63 sectors/track
!!!! /dev/sdc: 228946 cylinders, 32 heads, 32 sectors/track !!!!

sfdisk -g /dev/sdd;sfdisk -G /dev/sdd
/dev/sdd: 14593 cylinders, 255 heads, 63 sectors/track
/dev/sdd: 14593 cylinders, 255 heads, 63 sectors/track

I have /dev/sdc{1,2} mounted and used by /dev/md0, /dev/md1 RAID1. I
would like to add /dev/sdd{1,2} to these RAID's but sfdisk has problems
when I try to make partitions on /dev/sdd.

sfdisk -d /dev/sdc | sfdisk /dev/sdd
Checking that no-one is using this disk right now ...
OK

Disk /dev/sdd: 14593 cylinders, 255 heads, 63 sectors/track
Old situation:
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

   Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sdd1          0       -       0          0    0  Empty

/dev/sdd4          0       -       0          0    0  Empty
Warning: given size (233937920) exceeds max allowable size (233933761)

sfdisk: bad input

As I see in fdisk's and sfdisk output there is a difference at some level
in disk geometry. Could you suggest a solution?

Best regards,
Rafal.
