Hi, I have a Linux dd file thats an image of the entire disk. If I use the fdisk-linux and do : # fdisk -ul some-big-3.5.0_Update_2-103909.i386.dd You must set cylinders. You can do this from the extra functions menu. Disk some-big-3.5.0_Update_2-103909.i386.dd: 0 MB, 0 bytes 64 heads, 32 sectors/track, 0 cylinders, total 0 sectors Units = sectors of 1 * 512 = 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System some-big-3.5.0_Update_2-103909.i386.dd1 8192 1535999 763904 5 Extended some-big-3.5.0_Update_2-103909.i386.dd4 * 32 8191 4080 4 FAT16 <32M some-big-3.5.0_Update_2-103909.i386.dd5 8224 106495 49136 6 FAT16 some-big-3.5.0_Update_2-103909.i386.dd6 106528 204799 49136 6 FAT16 some-big-3.5.0_Update_2-103909.i386.dd7 204832 430079 112624 fc Unknown some-big-3.5.0_Update_2-103909.i386.dd8 430112 1535999 552944 6 FAT16 Partition table entries are not in disk order It looks like a good filesystem. So then I : mdconfig -a -t vnode -f some-big-3.5.0_Update_2-103909.i386.dd -u 0 mount -t msdos /dev/md0s5 /mnt to be able to get the dd5 on /mnt. I then edited the files I wanted, replaced them, and copied back to /mnt. I did "umount /mnt" and copied the dd file back to where it needed to be. It seems it didn't like it, and I'm trying to find out if editing it the way I did wasn't quite "allowed". Thanks, Tuc
