Ubuntu 10.04 LTS Overlap Partitions

Asked by tomdean

I have two disks, one IDE and one SATA. I think I have upgraded to several versions on this disk.
The IDE disk is used for backup. The SATA disk contains Ubuntu 10.04 LTS. Partitions 2 and 5
overlap exactly.
Is this a problem? Should I correct this? How?

# sudo fdisk -l
   Device Boot Start End Blocks Id System
/dev/sda1 1 20023 160834716 83 Linux
   Device Boot Start End Blocks Id System

You should not be worried about that, because sdb2 is extended partition.

"An Extended Partition is a type of partition that you can create only on basic master boot record (MBR) disks. Extended Partitions are useful if you want to create more than four volumes on a basic MBR disk. Unlike primary partitions, you do not format an extended partition with a file system and then assign a drive letter to it. Instead, you create one or more logical drives within the extended partition. After you create a logical drive, you format it and assign it a drive letter. An MBR disk can have up to four primary partitions, or three primary partitions, one extended partition, and multiple logical drives."
