That all seems normal, other than the unknown partition table, but the 
device might be all one unpartitioned disk.. at what point is it failing?

Mounting it just claims wrong FS type.  And I've tried most file systems
I can think of just to be sure.

Can you read the whole volume with 'dd'? If yes, you could provide
a hex dump of the first few sectors? Probably someone on this list will
recognize the format...

I did this and looked into the image myself.  It definitely looks like a
FAT32 image.

I've made the first MB available here:

mass-storage problems with Archos AV500

[David Weinehall]

I've got an Archos AV500 here (running the very latest firmware), pretty
much acting as a doorstop, since I cannot get it to be recognized
properly by Linux.

This device has two modes, and one usb-id for each:

Windows device mode:
0e79:1129

mass storage mode:
0e79:1128

I didn't really expect any luck with the former (and didn't have any
either), but I was kind of hoping that the latter would be supported.
Not so.

Relevant info from dmesg:

This is with linux-image-2.6.19-7-generic 2.6.19-7.10 from Ubuntu edgy.
I get similar results with a home-brew 2.6.18-rc4.

Any mass storage quirk needed that might be missing?

It seems to be working just fine. What does parted say about it?

In the end it turned out not even Windows recognized the filesystem.
Reformatting solved the issue.  Sorry for the false alarm.
