OK, it looks like you have one hard drive in your computer, divided up into one physical partition and one logical partition (with 4 defined logical volumes / drive letters).
I still recommed backing everything up (all 5 "drives"), but if careful, you can just get away with backing up your logical drive (I:, L:, J:, K: )
It looks like you have about 43GB of data to back up on the logical drive. Can you get your hands on a USB external hard drive with about 50-60GB of free space? This is your best bet. I have one you can borrow, if you can't get one. I would copy (not move) everything onto it. If that is not an option, you can fit about 20GB of that on the H: drive (create a folder on the H: drive and copy about 20 GB of data into that folder), and burn the rest to DVD. The second option will take awhile. Regardless, without a third party utility (such as partition magic, etc) you will need a place to put those files while you modify the drive.
Once everything on the logical partition is backed up, you can use disk manager to adjust volume sizes. You may have to delete the logical partition, but I believe that if you delete the I: drive, you can then expand the L: drive to fill up the newly available space. If you cannot adjust the logical volumes individually, just delete the logical partition,and recreate them as you like. When you're done, just copy everything back.
Be careful if you delete anything, and make sure you are only messing with the logical volumes, not the primary physical partition, which is your H: drive. You should not have to touch your H: drive.
Here is why you want to copy vs. move. If somethig happens during the copy, you can just start the copy over and overwrite everyting. If you moved the files and something went wrong, you'll have a partial directory structure on the target and a partial on the source. If you start over, it will see the same folder on the target as the source, and ask to overwrite. If you say yes, it will overwrite the target folder with the source folder, even though they contain different files. IOW, you'll lose files.
When you are done copying, select all files on the source (CTRL-A), and right click, select properties. Do the same on the target. Make sure the # of files and # of folders are exactly the same, with the total size being very close. The total size may differ a little depending on how the drive compresses the files.
I am saying all this from memory, and unfortunately I dont have a computer with a similar setup handy to verify the steps.
Perhaps someone can chime in on the ability to resize logical space?
Whatever you do, just make sure you are only operating on the logical partition and not on the whole drive or the physical partition (H)
Good luck, and let me know if you need anything. I'll be doing my PHH today, but I'll check in periodically
I think I will get back to truck stuff now.
