I think the fdisk in 6 tries to align on 4k boundaries. Does fdisk -c do the
same thing?

Scott - thanks I just tried -cu and same result.

have you tried sfdisk?

Steve - I had not - but asking sfdisk to list the device on centos has 
the wrong geometry to start
with just like fdisk does. it should be 255 heads and 63 sectors.

sfdisk -v
sfdisk (util-linux-ng 2.17.2)

  sfdisk -l /dev/sde

Disk /dev/sde: 1022 cylinders, 247 heads, 62 sectors/track
Warning: The partition table looks like it was made
   for C/H/S=*/255/63 (instead of 1022/247/62).
For this listing I'll assume that geometry.
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

    Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sde1   *      0+    974-    975-   7830616+   b  W95 FAT32
         end: (c,h,s) expected (974,221,63) found (1023,254,63)

This is centos 5
