Maidjeurtam asks: "I'm a multi-OS user. Although Linux is what I use the most these days (I run it on my primary P4 box and on my iBook), I also run Mac OS X and a Windows XP on other machines. Of course, those boxes are networked, but sometimes, I just prefer to plug one machine's hard disk into another. I often work with big DV files (> 4GiB) and it looks like I have no other choice than having a different filesystem on each of my boxes. Granted, Linux can read NTFS (Macs can too) and even write to NTFS partitions thanks to tools like Captive, but I don't like the idea of running Windows code on my Linux box. In fact, I don't want my data stored on a proprietary, closed filesystem. I've googled a bit and it seems there's no modern (free-as-in-speech) filesystem I can install on Windows. I'd love to have ReiserFS running on my XP box, for example. Am I condemned to stay with NTFS, or do you guys know of a Windows-compatible, open filesystem that I can use?"
