oh that makes a lot of sense now. i remember reading somewhere that the ext2 translator uses the other 2GB for something else. the ext2 translator maps each byte as a different address? i don't know about how it works internally, but shouldn't data-addressing be kept in sector-blocks (512 bytes)? if i sound ignorant please don't confuse it with arrogance and excuse it. i have some experience with file system driver writing and HURD translators, and a lot of free time. if the code isn't too difficult to dig through i'll attempt at patching (or...gulp rewriting). i know i know, less talking more hacking. -rian _______________________________________________ Bug-hurd mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/bug-hurd
