Title:
  after using cfdisk to format a mac disk, parted still uses the mac
  partition table

Status in “util-linux” package in Ubuntu:
  Triaged

Bug description:
  parted reports a disk as having an hfs+ partition, when in fact it has
  a single ext3 partition.

  fdisk, sfdisk, cfdisk and gdisk all report the disk with an ext3
  partition as expected, and fsck reports that partition as clean.

  I tried both my standard parted 2.2 (2.2-5ubuntu5 in "Ubuntu 10.04.3
  LTS") and a freshly compiled parted 3.0 with the same result.
