Damn. Looks like LBA is being disabled, most likely because the drive was initially partitioned without LBA. Parted might be able to fix this, but I'm not sure. You may have to restart from scratch.... If you are brave, follow these steps _very_ carefully to see if it is simply due to the partitioning of the disk. If you are careful, you can do this without damaging any data on your system. All of this will be from the livecd: First, backup your partition table and MBR to a floppy disk: # mount /dev/fd0 /mnt/floppy # dd if=/dev/hda of=/mnt/floppy/mbr.backup bs=512 count=1 # fdisk -l /dev/hda > /mnt/floppy/partitions.txt # umount /mnt/floppy Now we need to erase things: # dd if=/dev/zero of=/dev/hda bs=512 count=1 ## DOUBLE CHECK THIS LINE And reboot the live CD. If LBA is working, CHS should now be reported as xxx/255/63. To restore things, run: # mount /dev/fd0 /mnt/floppy # dd if=/mnt/floppy/mbr.backup of=/dev/hda bs=512 count=1 ## DOUBLE CHECK AGAIN If you have logical partitions also, use the data in /mnt/floppy/partitions.txt to recreate them using fdisk with the exact starting cylinder, ending cylinder, and Id. # umount /mnt/floppy And reboot. If all went well, you didn't lose any data... If you do decide to rebuild the system, and we did not get LBA mode from blanking the partition table and rebooting above, then you can try running fdisk with "-H 255", partition the drive, and reboot. That should basically force things to the right mode. -Richard -- gentoo-user@gentoo.org mailing list
