#275 closed System Defect (wontfix)

NTFS filesystem detected as FAT or msdosfs

Reported by: Goette Owned by:
Priority: major Milestone: 8.1
Component: System Tool Version: 8.0
Keywords: Cc: trac-bugs@…


Using 'fdisk -s /dev/da0' shows da0s1 as FAT (or msdosfs cannot remember) when it is NTFS. How can this be?

Also this command is not as explicit as in linux, it is not clear what there is in the slices or the hard disk.

  • Resolution set to wontfix
  • Status changed from new to closed

Since this bug is in the "fdisk" command itself, it'll need to be reported to the FreeBSD project for fixing:

Please open a PR at the URL above with the details of this error and hopefully a developer can get this fixed in fdisk for 8.1 :)
