No need to do that. Can you post the results of fdisk -l and show what you have in mind?

/dev/hda1 is too small.

Code:

Disk /dev/hda: 60.0 GB, 60040544256 bytes
16 heads, 63 sectors/track, 116336 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        1221      615352+  83  Linux
/dev/hda2            1222        2558      673848   82  Linux swap / Solaris
/dev/hda3            2559      116336    57344112    f  W95 Ext'd (LBA)
/dev/hda5            2559       63511    30720280+  83  Linux
/dev/hda6           63512      116336    26623768+  83  Linux

Disk /dev/hdb: 100.0 GB, 100030242816 bytes
255 heads, 63 sectors/track, 12161 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdb1   *           1       12161    97683201    c  W95 FAT32 (LBA)

i'm confused now, i clearly remember formatting hdb1 ext3 and it has a 4.4gb file & a lost+found directory on it which is liek impossible for a fat32 partition, its also listed as ext3 in /etc/fstab

Unfortunately, /dev/hda2 is not big enough that using it would be worth your trouble.
The next one over is /dev/hda3 ( Extended ) and you can't remove that without messing with 5 and 6.
If it was my system, I'd fix the partitions on /dev/hdb and use a livecd with partimage . Save the partimage image to someplace on /dev/hdb and also save your jpg and mp3 stuff in a folder on /dev/hdb .
From a livecd still...
I would remove all partitions on /dev/hda and create /dev/hda1 to the larger size which you desire.
Next, restore the partimage image to the new /dev/hda1.
Next, run the command: e2fsck -f /dev/hda1
Next, run the command: resize2fs -f /dev/hda1
Next, create the swap partition and run the command: mkswap /dev/hda2
Next, create the Extended partition
EDIT: If partitions 5 and 6 are used for something like /home and /usr then you will want to backup those partitions and restore them with partimage.

Finally, create partitions 5 and 6
Format them, for example... mkfs.ext3 /dev/hda5 && mkfs.ext3 /dev/hda6
