How large is your hard drive exactly and is it a real IDE hard drive or some kind of flash? If the disk/flash is very small, ext3 may be a bad choice since it's a journalling file system which means that a) it'll take up quite a significant portion of space on a small drive and b) it'll write to the same sectors all the time, which will kill the flash in no time. -- Martin Michlmayr http://www.cyrius.com/
