I know that using whole disks gives the benefit that zfs will to try to enable disk write cache on it. But I'm scared of what would happen if I plug such a disk on some other machine, that runs some other OS (Windows for example) since that disk will not have a valid MBR. Will it try to restore a valid MBR and destroy a zpool in the process? ____________________________________________________________________________________ Sick sense of humor? Visit Yahoo!
