Loopback filesystems in a file on vfat.

TWIMC.

on your NoDo list, you list alternative filesystems.
I appreciate your reasons for choosing not to support this.  :)

In addition to listing partitioning the device as a work around on the NoDo list, perhaps consider mentioning loopback filesystems.

If the issue is just preserving file attributes that fat doesn't support, then with a loopback filesystem you can use whatever filesystem you like. I don't really know or care whether MS can support them, but on a complete OS, it allows you to (maybe temporarily) make a disk image in a file on the player, and mount it like a disk. You could even use strong crypto if need be. http://tldp.org/HOWTO/html_single/Cryptoloop-HOWTO/#loopdevice-setup

Sitting it on a vfat filesystem, you'd obviously loose any other benefits of a more sophisticated file system, but seriously we're talking about writing to a music player... Doing it on a flash based disk could be bad. I don't know. Probably depends on how it's done. Journaling filesystems are apparently really bad for flash disks because they write a lot of little bits of data all the time. Apparently they're broken for loopback in some cirtumstances anyway.

just a thought.

Please follow our forum guidelines. I have no idea whatsoever what "TWIMC" means, and we ask that you attempt to use real words, and restrict yourself to the abbreviations in the project glossary.

Can you think of any real use for this on a DAP?

Llorean:
I *think* he's just referring to people who may want to use their DAP also as an external HD. So, not something that would be used except when attached to a host PC.
