screenshot of cfdisk after the new partition was created
I created the new partition by selecting the free space, pressin [N]ew and accepting the offered size ( the entire free space ). I'm not sure if cfdisk is even recommended for use - I vaguely recall that there were some disk features that only fdisk could handle. I'm curious if everything works properly if you use fdisk? Apologies for the unresponsiveness of the previous util-linux packager... No response, can't blame the dude, can't fix the problem. Seems like cfdisk is confused when partitions are not in physical order. Here is how to reproduce it without harming your hard drive : 1. dd if=/dev/zero of=testfile bs=1024 count=80 2. mv /dev/hde /dev/hde.backup 3. mv /dev/loop0 /dev/hde 4. losetup /dev/hde testfile 5. fdisk /dev/hde # enter the following commands : x s 1 h 1 c 80 r o n p 1 2 10 n e 2 11 80 n l 12 20 n l 60 70 n l 22 30 w *EOF* # do not enter this 6. cfdisk /dev/hde : - select the free space between hde7 and hde6, press 'n', press ENTER, voila , two hde7 partitions listed ! 7. to clean up : losetup -d /dev/hde ; mv /dev/hde /dev/loop0 ; mv /dev/hde.backup /dev/hde rm testfile 8. fdisk and cfdisk were from util-linux-2.10s-12.rpm this time This is a good explanation of the problem, but the response remains as before - use fdisk, not cfdisk. Sorry about the confusion, I've removed cfdisk from the util-linux package so that this type of confusion doesn't happen again. |
My disk has the partitions hda1, hda2 <hda5-10> When I try to add a new partition in cfdisk, using the free disk space, the new partition gets the name hda8 and the old hda8 is renamed to hda9, giving two hda9's ! I'm using cfdisk from util-linux-2.10p-4 on Fisher/i386. cat /proc/ide/hda/geometry : physical 39560/16/63 logical 2482/255/63 fdisk -l -u /dev/hda : kernel version 132097 Disk /dev/hda: 255 heads, 63 sectors, 2482 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 255 2048256 7 HPFS/NTFS Partition 1 does not end on cylinder boundary: phys=(1023, 0, 63) should be (1023, 254, 63) /dev/hda2 256 2482 17888377+ f Win95 Ext'd (LBA) Partition 2 does not end on cylinder boundary: phys=(1023, 13, 63) should be (1023, 254, 63) /dev/hda5 256 892 5116671 7 HPFS/NTFS /dev/hda6 893 1283 3138754+ 7 HPFS/NTFS /dev/hda7 1283 1665 3070305 7 HPFS/NTFS /dev/hda8 2300 2482 1469947+ c Win95 FAT32 (LBA) /dev/hda9 1666 1716 409626 82 Linux swap /dev/hda10 1717 2000 2281198+ 83 Linux Partition table entries are not in disk order sfdisk -l /dev/hda : Disk /dev/hda: 2482 cylinders, 255 heads, 63 sectors/track Warning: The first partition looks like it was made for C/H/S=*/1/63 (instead of 2482/255/63).

Note that I never saved the "weird" partition tables from cfdisk to disk !
