problems resizing root partition

[John Hendrickx]

Hello,

I'm having problems trying to resize my root and home partitions. When I run
"parted /dev/hdb print" I get:

Disk geometry: 1-767, 4032k cylinders
Minor    Start    End      Type            Filesystem     Flags
1        1        64       primary         FAT            boot
2        65       767      extended
5        65       67       logical         ext2
6        68       416      logical         ext2
7        417      767      logical         ext2                                 

Parted reports my disk geometry as 767/128/63.

But when I boot using the parted bootdisk, I get different values:

Minor    Start    End      Type            Filesystem     Flags
1        0.0      252.0    primary         FAT            boot
2        252.0    3020.0   extended
5        252.0    263.8    logical         ext2
6        263.8    1638.0   logical         ext2
7        1638.0   3020.1   logical         ext2

Using the bootdisk, I can't get the resize option to work. I enter

resize 7 2438.0 3020.1

But I get an error that I can't write past the end of the partition (I don't
remember the exact text). Trying "resize 7 2438.0 3020.0" doesn't help, I get a
different error message. Could you point out what I'm doing wrong here?

I'm using  partboot-1.2.9 and I've installed parted-1.0.17 on my harddisk. When
I installed Linux-Mandrake, I went with the defaults and created a large 1.3G
home directory. Now I want to shrink it to 500M and assign the rest to the root
partition. 

Any help appreciated,
