Problems with Extended partitions

Post by Houchy » Thu Oct 08, 2009 4:41 pm

Hello all!

looking at my disk configuration, I'm seeing some weird things I'd like to understand.

1- On sda, I installed Windows XP on a 20GB partition and I created a 60GB NTFS partition. However fdisk shows 3 partitions? Why? Is there an extended partition? Can I make it a primary partition without destroying everything?

2- I want to create an image on my XP partition (sda5), with this configuration, will the restoration work?

Here is the description of my file system :

Code: Select all

Disk /dev/sda: 82.0 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xac68976f

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        7413    59544891    7  HPFS/NTFS
/dev/sda2            7414        9963    20482875    f  W95 Ext'd (LBA)
/dev/sda5            7414        9963    20482843+   7  HPFS/NTFS

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x51195119

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1       31871   256003776    7  HPFS/NTFS
/dev/sdb2           58252       60673    19454683+   f  W95 Ext'd (LBA)
/dev/sdb3           60674       60801     1028160   82  Linux swap / Solaris
/dev/sdb5           58252       60673    19454652   83  Linux
3- My 500GB Hard drive (sdb), on which Ubuntu is installed has an Extended partition. Is it possible to switch back to have only 3 Primary partitions?

Thanks a lot for your help!

Questions #1 and #3 are about partitioning -- probably best asked elsewhere.

#2 The only way to see whether "it works" is to try a test save and restore.
