I'm running OS/2 Warp with HPFS on several of my drives. I noticed that Linux 1.1 fdisk reveals two different file system identifiers for these HPFS partitions:
/dev/sda5 id 7 OS/2 HPFS /dev/hda2 id 17 Unknown The Unknown partition type (id 17) was created by OS/2 Warp fdisk during the installation process. It is also a primary partition. The HPFS partition type (id 7) was created by OS/2 Warp after installation. Note that this is an extended partition. Has anybody else observed the two different identifers for HPFS filesystems? Is this a Bug? Linux produces some error messages when mounting the id 17 filesystem but it everything seems to work ok. I didn't observe any error messages when mounting the id 7 filesystem which also works fine. OS/2 Warp doesn't complain at all.
