Using flash drive both to boot a LiveCD and to share data between OSes


I have Linux, Windows XP, and Mac OS X computers in my household. I have purchased a 16GB flash drive recently, my first flash drive so bear with me here.

What I would like to do is partition the flash drive using fdisk and put a few different LiveCDs (Knoppix, Ubuntu, etc.) onto different partitions. I'll then install and configure grub to boot to the different OSes. What I would then like to do is to leave one extra partition which will be formatted using a filesystem that my Linux, Windows, and Mac can all read from/write to (FAT32?), so that I can use the flash drive to share data between all 3 OSes.

So, I have two questions:

1) Does anyone have experience with doing something like this, that can tell me if splitting the USB stick into several partitions will cause Windows and/or Mac OS X not to recognize the partition I want to use to share data? I would hope that Windows would treat it somewhat like it treats a hard drive during a Windows install... that is, it would make available partitions which are formatted using filesystems that Windows knows how to use, and ignore those that it doesn't... but I am not sure.

2) Is there any filesystem that is better than FAT32 (performance-wise), which can freely be read and write to by all three OSes? I'm pretty sure the answer to this one is no.


Thanks in advance!

I think puppy linux has an install option where you can install to only a part of the USB drive and leave the other space usable by other partitions.

Interesting... I'll look into that.

By FAT, do you mean any FAT filesystem (FAT, FAT16, FAT32)? To have a volume size any larger than 2GB, FAT or FAT16 wouldn't cut it, so I'd want to use FAT32. I've successfully written to a FAT32 partition using Linux, but have never tested using OS X.

afaik, FAT32 works fine in all distros ... I haven't tested / used OS X but I am pretty sure that if there was an issue I would have heard about it by now

Good point. I'll check out Puppy Linux once the flash drive arrives this weekend. Thanks for the recommendation.
