When you fdisk'd hda, did it successfully re-read the partition table, or
did it fail with a device/resource busy message?
The last time I saw a device too small was because the kernel hadn't noticed
that the partition had been created.
reboot is the simplest cure, or call a sysctl to re-read the partition table
for the purists :)
good luck
Jim
