Well the title says it after installing leopard NTFS-3G no longer works so i cant write to NTFS so i copied all 300 gigs i had on that drive to my main hard drive and now i need to format to a file system compatible with windows and OS X, I know ext2 can be read/write in windows by installing an IFS my main reason of posting was to to see if anyone has done this and how well Ext2 is for Data reliability and also can it hold files bigger than 4 GB unlike the FAT32 partitions?
