Bad bug in partitioning in squeeze installer

["Andrew Hill" <andru@treshna.com>]

Hi All

I'm working from the nightly builds of squeeze. I've noticed a number of
desktops and servers I have been testing with squeeze have been generated
with incorrect partition tables, causing data loss and corruption.

Using the text GUI partitioning tool it appears to make the cylinders
inclusive, not exclusive.


fdisk /dev/sda -l

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xe0c5913d

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2550    20482843+  83  Linux
/dev/sda2            2551       17750   122093748    7  HPFS/NTFS
/dev/sda3           17750       55804   305664000   83  Linux
/dev/sda4           55804       60802    40144897    5  Extended
/dev/sda5           55804       56290     3905536   82  Linux swap / Solaris
/dev/sda6           56290       60802    36238336   83  Linux

As you can see sda3/sda5/sda6 all have overlapping cylinders.

This is error from cfdisk
FATAL ERROR: Bad primary partition 3: Partition ends in the final partial
cylinder


I had the same problem on 3 different computers I have checked. All of
them suffering the same overlapping problem.
