NTFS partition recognized as OS/2 HPFS
/dev/sda1 (installing to sdb) is NT 4.0 NTFS which disk druid
recognizes as an OS/2 HPFS partition
Both NTFS and HPFS have the same partition type (7) so that is the reason that
they are coming up as the same. Disk Druid is picking the first one that it
comes to to identify the type 7 partition that it is looking at, and that label
happens to be HPFS.
