[Wine] wine: /intended/PREFIXdirectory/not owned by you

[Indubitableness]

I am attempting to create a folder for my wineprefixes on my external hard disk. The plan is to symlink to that location from inside my user folder (ie. ~/.wine/PREFIXES -> $iomega/.wineprefixes)
For reference:
$iomega=/media/Iomega_HDD
This is a 400GB external drive with a single NTFS partition.

The plan is to create folders for all my WINEPREFIXes at $iomega/.wineprefixes
(Example: $iomega/.wineprefixes/Blizzard)

I keep getting the following error: wine: /media/Iomega_HDD/.wineprefixes is not owned by you

Okay, I figure, I'll make sure it's owned by me.

chown -R indubitableness.users $iomega/.wineprefixes

No go. Same error. Why is this happening? I'm seeing some posts that seem to imply that maybe wine just simply doesn't support making Prefixes outside of one's user folder. I really hope this isn't the case as I keep losing all my installed games every time I break my linux installs (every time I try some new unfamiliar advanced thing I have no qualifications for messing around with) and putting my prefixes on my back up drive would be the perfect solution.
