[lug] FAT32 USB drive

[geobodley at aol.com]

I put a USB stick with my back up files which was formatted to ext4 into my Samsung tablet and Android formatted it without asking my permission.   My files were there but I couldn't see them.   I was able to recover them, but without their proper name which is a real pain.   You have to look at them one by one to see what it is.   I hate to use FAT 32, but sometimes you are forced to and I despise Android taking it upon itself to format a device without ask for permission.

Folks,
I have a digital piano which can put stuff on USB devices (unspecified filesystem), so I formatted an USB drive to FAT32, put some stuff from the piano to it and tried to read them from my linux box.
Funny enough, the drive showed empty in Linux, but the content was there when looking from the piano. I tried on a Mac which responded "The disk you inserted was not readable by this computer".
So I tried Android. In fact I can see the digital piano files via Android (yay!) 

Funny thing, if I create files and directories on that USB drive from Linux, none of them shows up in Android.
So it looks like this USB drive has two lives: one which is visible only from Linux, and the other which is visible from the digital piano and Android.

Am I still sleeping and having a bad dream? Simple Googling did not reveal anything obvious....
Thanks for any clues!
Davide
