I've got the same problem. I installed a -current snapshot about 2 1/2
weeks back, and the fdisk editor obviously wrote the partition tables
with a different assumption about disk geometry than 4.7-stable. Now,
my partition tables have boundaries that Linux's fdisk disagrees with.
For example, using Linux fdisk from my Gentoo install:
fdisk -l /dev/hda
Disk /dev/hda: 255 heads, 63 sectors, 2432 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 36 289138+ a0 IBM Thinkpad hibernation
Partition 1 does not end on cylinder boundary:
phys=(573, 11, 63) should be (573, 254, 63)
/dev/hda2 * 37 765 5855692+ c Win95 FAT32 (LBA)
Partition 2 does not end on cylinder boundary:
phys=(1023, 2, 63) should be (1023, 254, 63)
/dev/hda3 766 1403 5124735 5 Extended
/dev/hda4 1404 2432 8265442+ 82 Linux swap
/dev/hda5 766 767 16033+ 83 Linux
/dev/hda6 768 778 88326 83 Linux
/dev/hda7 779 798 160618+ 83 Linux
/dev/hda8 799 831 265041 83 Linux
/dev/hda9 832 1403 4594558+ 83 Linux
I never had this problem with FreeBSD-stable and Linux. And now, with
the DP2 install CD, I can't delete any partitions with "D", as the
cursor just moves up.
Here is FreeBSD's idea of my disk geometry:
C/H/S == 38760/16/53
Here is what Linux reports:
dmesg | grep hda
ide0: BM-DMA at 0x1080-0x1087, BIOS settings: hda:DMA, hdb:pio
hda: TOSHIBA MK2016GAP, ATA DISK drive
hda: 39070080 sectors (20004 MB), CHS=2432/255/63, UDMA(33)
So, I tried pressing "G", and entering in "2432/255/63", but the DP2
fdisk editor still wouldn't let me delete any partitions.
I suppose GEOM is the "culprit" here.
