Fixing errant partitions

[David Baron <d_baron@012.net.il>]

Partitions, created by linux fdisk, seem to have errors (disabling 
parted/qtparted, etc.) The table looks like this (I do not know whether it 
made it this way--I only gave fdisk types and sizes, or other things caused 
the errors. There were originally two fat32s plus one linux and swap on this 
disk, made by PartionMagic--one fat32 was eliminated and the space taken for 
several ext3 partitions made using linux fdisk):

   Device Boot      Start         End      Blocks   Id  System

Partition table entries are not in disk order

Fdisk 'v' command complains about hdb5 and hdb6 overlap. Appears as if the 
same is true for hdb6 and hdb7. How do I SAFELY fixe this up? hdb2 is either 
not needed or needs to be shrunk to same size and hdb5 in which case hdb5 
should probably be tagged 'b' -- the only simple change it seems clear how to 
do.

Any advice appreciated. Thanks.
