Is it possible to update my ipod from a different computer without it erasing all the songs on my ipod?

connect your ipod and open it up (the folder) then go to tools, folder options and display hidden folders. then click on music, and there will be a lot of folders with music in each one named oddly, they are all your songs but with weird names, just copy all the folders to the computer this is assuming you're using windows, or you can just copy all the songs from your original computer

you could continually pass into your ipod settings once you have it plugged into your comp and consider the field that asserts manually manags songs, then all you need to do is spotlight and drag songs onto your ipod out of your friends comp. the only subject is you could no longer replace on your comp after that with out dragging the comparable way or you may lose all your friends songs.

Yeah! Ok, I, a while ago, ask the same question, but now I've got the answer! You could either go to www.apple.com and search for your solution or read the solution that I got off that website!

How to use your iPod to move your music to a new computer

Got a new computer? Because your iPod contains a high-capacity hard drive, you can use it to move all your music from your old computer to the new one. Note that you can't transfer songs from the iPod library to iTunes, so you'll need to follow the steps below to use iPod as a hard disk to transfer music files from one computer to another. Once you have the files transferred, you'll need to authorize any iTunes Music Store content. If you won't be using your old computer, you'll want to deauthorize it.

Important: Windows operating systems don't recognize Mac OS-formatted disks (HFS or HFS Plus formats), so you can't use a Mac-formatted iPod to move your music to a Windows PC. See "iPod: How to determine iPod's hard disk format" if you're not sure what format your iPod is.

Switch the iPod to manual update and enable disk use

The first thing you need to do to use your iPod as a disk is to turn on manual update and enable disk use. To do this:

1.Open iTunes on your old computer.

2.Connect your iPod to your old computer and wait for it to appear in iTunes.

3.Select your iPod in the Source list and click the iPod button that appears in the lower right corner of the iTunes window.

4.Click the Manually manage songs and playlists button. Changing from automatic updating to manual puts a check mark by Enable disk use. A message says "Disabling automatic update requires manually unmounting the iPod before each disconnect."

5.Click OK in the message window.

6.Click OK in the iPod Preferences window.

Is all the music together?

To make the move as easy as possible, be sure your music is all in one place.

1.From the iTunes menu, choose Preferences.

2.Click Advanced.

3.Look to see if the checkbox for "Copy files to iTunes Music folder when adding to library" is selected. If it is, skip ahead to Is there enough room on the iPod. If it not, continue to step 4.

4.Select the "Copy files to iTunes Music folder when adding to library" checkbox.

5.Click OK.

6.From the Advanced menu, choose Consolidate Library. A window appears reading: "Consolidating your library will copy all of your music into the iTunes music folder. This cannot be undone."

7.Click Consolidate.

Is there enough room on the iPod?

iPod shares its hard disk space between the songs that iTunes puts on it and any files you've added when using its disk mode. To transfer music with your iPod, you need enough free space to hold a copy of all your music files in addition to any copies that may already have been placed by iTunes (this is because songs placed on the iPod by iTunes cannot be copied off the iPod while in disk mode). To figure out how much space you have on your iPod:

1.Open iTunes on your old computer.

2.Click on Library in the Source list. The size of your library appears at the bottom of the iTunes window:

3.Connect your iPod to your old computer and wait for it to appear in iTunes.

4.Click the iPod in the Source list.

5.The amount of free space on the iPod appears near the bottom right of the iTunes window.

If the amount of free space left on your iPod is larger than your library, skip to Copy iTunes folder to iPod.

Free up space on the iPod

If your library is larger than the amount of free space on your iPod, you'll need to free up some space on it. Here's how:

1.Click your iPod in the source list.

2.Click any song that appears in the main part of the iTunes window (to the right).

3.From the Edit menu, choose Select All.

Important: The next step will delete all music from your iPod. If you have been using automatic update you don't need to worry, because all your music is also on your computer. If you have not been using automatic update, and your iPod has music on it from another source (other than your iTunes library), following the next step will delete that music.

4.Press delete on the keyboard. If you see a message that says "Are you sure you want to remove the selected items from the list?", click Yes.
