I did the same file/partition shuffle yesterday. create, move, destroy.
DO it the easy way. DOwnload the following
rescuedisc. It containg Gentoo distro and apps to let you backup/restore and play with your partitions.
It's best to boot to this because to run a partition manager, you don't want any partitoins you want to effect to be mounted, busy.
So, burn the disk, then boot to it. Type menu. arrow down to run rescue disc. Gentoo will load and you will be able to run partimage to save your stuff prior to modifying the partition.
THen, run run_qtparted to do your thing to your partitions.
Yesterday I was able to perform these tasks with no errors. I wanted to modify my partitions to reflect my current fc2 plan, so I put all the data from my windows partitions into one newly resized one, (for this I used ntfs resize on a floppy - bootable) then I deleted and created a new partition on the hdd for backups. (hdb2)
THen on my master hdd, where windows (hda1) and fc2 (hda5) live, I resized the extended (with logical drives) partition that is my / partition (ext3 - hda6). I then made another partition on this drive for all my music.
It was really quite easy -- it just took some time. Only 'cos I was chickenshit. That was ALL my data.
Running partimage was easy. I mounted the partition I earlier created for backups...we're running the gentoo disc here. Then running partimage I told it to make an image of hda6 and put it in the new partition I just made, and call it...
F5, F5 and 18 minutes later a 1.67gb back up of the 6.3gb worth of files in my / partition.
Resizing that extended partition was easy -- since I booted to gentoo on a disc, I could use qtparted and just drag the slider, man. Choose the partition, right-click, resize...drag the slider.
Committ, reboot (to your hdd, change it back in the bios) and there you go. Now, mount your stuff. Goto your fstab file and write a permanent mount for your new stuff.
computing is cool.
