Troubles to find my partitioned disk

Hi, I'm very excited since last night I said good bye Windows, good bye Microsoft, and hello Linux!!. I installed ubuntu, and it has worked perfectly!! Well, I should said it had worked perfectly.After a while of usage, I decided to make a partition of my hard drive using Gparted, in order to put in that disk all my documents, and files, and in the root partition, all the system files. I made the partition 15 GB to system and 25 to my stuff (Q: is that enough for system files and software?)It took me a while, but I could do it. Proud of myself!!. However, I don't know how to take my files  and put them in the new partition. First of all, I dont have this tool that its supposed that I should have: System -> Administration -> Disks. (How do I make it appear??)When I do in the terminal: sudo fdisk -lI getDisk /dev/hda: 40.0 GB, 40007761920 bytes255 heads, 63 sectors/track, 4864 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/hda1 * 1 1418 11390053+ 83 Linux/dev/hda2 4683 4864 1461915 5 Extended/dev/hda3 1419 4682 26218080 83 Linux/dev/hda5 4683 4864 1461883+ 82 Linux swap / SolarisPartition table entries are not in disk orderBut I don't know if I have to format it as reiserfs, ext2, ext3, fat16, fat32 or linux-swap. I just chose reiserfs, since it looked nicer. No idea.Second, I didn't know if I had to put flags: boot, hidden, lba, lvm, palo, prep, raid.Third, I don't know if I have to mount it or not. It's mounted but I don't know where it is mounted. Should I unmount it? How?Finally, I open the file browser, but I can't find the partition. I was expecting to find something as c: or d:, as in Windows. I have to learn more, but I have been fighting with this the whole day.Can someone tell me what should I do??Thank you very much in advance,Andres
