Details

Sansapatcher is set to detect partition in FAT32 so if the player is formatted in FAT then it will not be detected. The Sansa is by default in FAT, not FAT32 and Windows set FAT as default when formatting the Sansa as well (I think it only applies to e250 because FAT does not support anything beyond 2GB, I believe). Maybe someone can slightly change the code to detect FAT partition as well or maybe change the manual to tell people to format their players in MSC mode with FAT32.
This task depends upon

This is a known issue. As I recall, FAT support broke at some point a while back and no one was very interested in fixing it. You should use FAT32.

sansapatcher doesn't look inside the FAT/FAT32 partition to see how it's formatted, it checks the partition type code in the partition table. Currently it only checks for type "0xb" which is "W95 FAT32".

It would be straightforward to check for other valid partition type codes - assuming they are valid. i.e. if the original Sansa firmware can boot and use such a partition, then sansapatcher should support it as well.

If someone can check what partition type a non-recognised (by sansapatcher) e200 has, I'll modify sansapatcher.

This patch should do it.

Oops, I forgot to mention the partition type is FAT16.

So has this been solved?

FAT16 partition type detection was added to sansapatcher quite a while ago. I think this is solved. Can someone who was having problems please report back if it works for them now?

I can confirm: this one is solved.
