Problems with Partition Magic 8.0

[Piotr]

I have a serious problem with logical structure of my 40GB disk in T42.
After installing Win XP I used Partition Magic 8.0 to create two FAT32 partitions. It worked fine. Then I decided to install Linux, so I used PM again to create a new partitions for a new system. I resized second FAT32 and using PM made 3 partitions: ext3 for / , another ext3 for /home and swap.
I installed Fedora Core 3 smoothly and dual boot worked good based on grub. I checked my logical disks in PM and it found some errors. I don’t remember the message, but I let PM correct them. I restarted the system and tried to enter into the IBM Access system, but the button didn’t start the program. I got the boot menu instead. I didn’t checked Access IBM button before I used PM for checking and mending my disk, so I don’t know if it worked after linux installation.
The second problem came when I extended memory. I didn’t need so big swap. I again used PM, this time to resize swap and create new, small FAT32 disk. It worked, but when I wanted to merge new partition with old one, PM generated error #510 The file system is not supported.
I tried to create big swap, like it was before, but PM finished with the same result – error #510 !!
Now my disk looked like a real mess:

10 GB – NTFS with original Win XP
7 GB – FAT32 disk
8 GB – FAT32 disk
380 MB – FAT32 disk  swap remains
130 MB – ext3 swap
50 MB – ext3 /boot
1,2 GB – ext3 /home
6,2 GB – ext3 /
4,7 GB – inactive FAT32 IBM SERICE

I want to merge two FAT partitions with the same cluster size. PM failed.
What can I do with it ? Any other disk tool will help ?
I can reinstall the whole system. I got everything in backup, but I think that recovering the system from the IBM Service partition won’t help.
