Not in any fs that journals that _data_, but ext3 doesn't do that by default. It only journals meta-data, and you can overwrite files just fine. If you do use ext3 in data-journalling mode (mount -o data=journal) that yes, it will be a lot slower than ext2. That's why the default is data=ordered. You can make it even faster, and still more safe than ext2, by using data=writeback. See "man mount". Mike. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
