results seem a little bit worse. There is an added message that says
that the system thinks that I have 16 heads. And, BTW, partition magic
says that the geometry changed from 255 heads to 16 heads.

sfdisk -l -H255 /dev/hdb
Warning: HDIO_GETGEO says that there are 16 heads

Disk /dev/hdb: 158816 cylinders, 255 heads, 63 sectors/track
