I'm not too keen on using 'fdisk' to switch active partitions anymore. Recently I used DOS 'fdisk' to switch the active partition from DOS to UNIX. After re-booting I found that 30,000 blocks of free space had disappeared from the root filesystem. I'm not positive but, I suspect that DOS 'fdisk' had something to do with it. I could not fix it using 'fsck'. I poked around in the superblock with 'fsdb' but found nothing. I ended up reformating the disk and loading from backups. -- John ---- Westminster Colorado
