Whenever a partition table is printed out, a consistency check is performed on the partition table entries. This check verifies that the physical and logical start and end points are identical, and that the partition starts and ends on a cylinder boundary (except for the first partition).

FYI: Data on this disk will be damaged. If data are important, Linux partitioning tools should not be used.

An extended partition ending 1 based cylinder 1024 or later *must* by type 0F or 85 if DOS or Windows is present. The type of hda6 should be 0B.

A FAT16 partition > 32 MB is type 06, or 0E for a primary FAT16 partition ending 1 based cylinder 1025 or later. Type 0C is used for primary FAT32 partitions ending 1 based cylinder 1025 or later. Logical FAT32 partitions always are type 0B.

If cylinders are numbered from 1, extended partitions ending cylinder 1025 (not 1024) or later should be type 0F or 85.

You can just change the type of hda4 from 05 to 0F (F), and the type of hda6 from 0C to 0B (B) using the Linux fdisk t command. This however should be done before hda6 is formatted.
