I also have:
Disk /dev/sda: 19457 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Disk /dev/sdb: 10337 cylinders, 240 heads, 63 sectors/track Units = cylinders of 7741440 bytes, blocks of 1024 bytes, counting from 0
OT: do you have any idea, why and how sfdisk determines the number of heads on the disk differently above, 240 vs. 255 ?
IIUC, it's calculated based upon upon the entries contained there. It's unusual to see two different head usages in the same two HD system. 240 is usually only found in use for laptop drives and Compaq desktops. For virtually all other desktop systems if a legacy cylinder multiple configuration is used, and the HD size is more than 4GB, 255 is the head count used.
The Windows version is all XP SR-3 here.
