how to resize partition with no data loss?


I have a dual boot laptop system with Suse 9.2 and Windows XP Pro. Using grub2 loader. 20GB hd with 10GB for both Windows and Suse. I am nearly out of space on the Windows NTFS partition and would like to reduce the size of the Linux partition by 2 GB and increase the Windows partition by the same.

Is there a Linux utility that will allow me to resize my Linux partition without data loss?

I also have just purchased Partition Magic 8. If i run this (from Windows of course) I get an error message:

"Partition magic has detected an error 116 on the partition starting at sector 20290095 on disk 1.
The starting LBA value is 20290095 and the CHS value is 15468704.
The LBA and CHS values must be equal.
Partition Magic has verified that the LBA value is correct and can fix the CHS value.
Would you like Partition magic to fix this error?"

Can I proceed with partition Magic or will it trash my system? Is there a Linux utility that I can use?

Suggestions?

Thank you

Just let PM fix the error, it is nothing major and then use PM to resize the linux and windows partitions. It is the easiest tool for the job.

Thanks wimnat.

If I use PM to resize the Linux partition do I have to worry about any data loss? Can my data be distributed all throughout the Linux partition where I will lose data that is near the end of the partition?

If so is there a good defrag utility that will make all the data contiguous and free the space at the end of the partition? Do I have to worry about this?

Nope PM is very clever. It calculates the free space on the partition not where the last piece of data on the partition is. Therefore, if it needs to move data it will. It can take some time though so when PM asks to reboot you might as well go and get a cup of tea. By the time you come back your partitions should be successfully resized with no data loss. I have never ever had a problem with PM BUT BACKUP ANYWAY. You never know when your HDD is going to fail.
