invalid assertion for number of heads in partprobe

[Phil Howard]

The partprobe command failed on Ubuntu 10.10 and also on Slackware
13.37 with a similar device.  The gist of the message suggests it is
applying an assertion of the device geometry number of heads against
the valid 63.  The actual value is 128.  Any value from 1 to 256 is
valid for heads (MS-DOS cannot handle more than 255 heads due to a bug
there, while sectors are the thing that is limited 63). Here is the
situation on Ubuntu which has parted version 2.3:

lorentz/root /root 227# partprobe /dev/sdh
