It finally exists!
http://www.paragon-drivers.com/extfs-windows/FULL Read Write support for Ext2/3/4 File-systems! you've no Idea how happy this makes me.
for those of you who don't know Ext is the file-system developed for unix and linux computers. It's a journaling file system meaning that even through a power failure it's hard to corrupt. Whats more they are built to spread the files out across the drive in such a way that they naturally prevent fragmentation you never have to defrag them. There are examples of high load ext filesystems that have been in service for more than 2 decades that are only at about 15% fragmentation.
So why am I so happy? this means that I can use ext4 on my 3TB drive and not have to worry about fragmentation or data loss like I would if it was NTFS!
