- Add new API device.[hc]::ntfs_device_heads_get() and make mkntfs use it.
- Provide a new command line option "-H" to mkntfs to allow the user to specify the number of heads manually. - Add new API device.[hc]::ntfs_device_sectors_per_track_get() and make mkntfs use it. - Provide a new command line option "-S" to mkntfs to allow the user to specify the number of sectors per track manually. (Logical change 1.345)
