Description of problem:
repartitioning and reformatting a drive that had a single ntfs partition
results in a ext2 or ext3 partition that cannot be mounted.
When attempting to mount the partition, mount returns with:
mount: fs type ntfs not supported by kernel
Somehow, a magic number or other identifier is left unmolested by the mkfs
utility. This results in the erroneous identification of the filesystem as
e2fsck correctly identifies the partition as ext2.
An octal dump (od -c) of the first 16 bytes of the partition show:
Ã« R 220 N T F S \0 002 \b \0 \0
Version-Release number of selected component (if applicable):
Didn't try. I have only one ntfs disk that needs repartitioning.
Whether mount should ignore the NTFS identifier or mkfs should remove or zero
the identifier is not known. I think that mkfs should do more.
I don't know of a workaround.
The kernel should not look at the first sector to autodetect a NTFS
