I think you have mac partitions (the first item is the partition map itself - very different from the dos partitions common on x86). Certainly, fdisk from util-linux doesn't know about mac disks, and I thought the same was true for cfdisk and sfdisk. Many years ago there was mac-fdisk, I think also known as pdisk, but nowadays the common tool for partitioning mac disks is probably parted. > [EMAIL PROTECTED]:~# mke2fs -v -j /dev/sdb1 > mke2fs 1.38 (30-Jun-2005) > Filesystem label= > OS type: Linux > Block size=4096 (log=2) > Fragment size=4096 (log=2) > 48840704 inodes, 97677200 blocks > 4883860 blocks (5.00%) reserved for the super user > First data block=0 > 2981 block groups > 32768 blocks per group, 32768 fragments per group > 16384 inodes per group > Superblock backups stored on blocks: > 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, > 2654208, > 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968 > > Writing inode tables: done > Creating journal (32768 blocks): done > Writing superblocks and filesystem accounting information: done > > This filesystem will be automatically checked every 36 mounts or > 180 days, whichever comes first.
