probably the partition has been created, as per EMC specification, with
an offset bigger than 63 sectors, so when you destroy it and recreate it
does not start anymore in the same place.

A better solution would have been, as Philip said, not to partition at
all, and align the start of the data, but since you are there, you could
try using a different tool, i.e. parted to extend the partition instead
of recreating with fdisk.
