How much of a disk wear factor is there with modern disk drives? The heads aren't touching the disk, and we have plenty of sectors which are constantly getting rewritten with traditional filesystems, with no ill effects as far as I know. For example, FAT filesystems, the superblock, block allocation bitmaps all are constantly getting rewritten today, and I haven't heard of disk manufacturers complaining that this is a horrible thing. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
