hmmm, if you could format the partition it would go away? hmmm, have you tried shrinking it MAX making a new fat32 partition in the free space and copying things over to that, then remove the cppied files shrink the ntfspartition, maximize the fat32one.- ... --- .- ... ---
if you did that is MIGHT work to finaly removing partition and recreating it and reverse the process.
i think it should work, okok, it would take a LOT of time, and be a possible risk, yes... but it should work.
hmmmm, come to think of it have you tried the captive ntfs? search foryum for it. might work.
