IPod won't backup?

Ok, I've been trying to update the latest version on my iPod Touch and it always says, iTunes could not back up the iPod because an unknown error occured (-20). I've been searching everywhere on what error code (-20) means, but nothing pops up!
Please help me!

i fixed the back up (-20) problem!
In iTunes go to preferences and delete any existing back ups. Then right click your device and click "Back Up" and voila!
I fixed this a long time ago but i couldn't come onlinefor my exams. sorry guys

My 4th gen ipod won't backup after it froze during a software update to 4.3.5. I had to cancel the backup at the start of the update and now it won't let me backup to my computer, freezes during backup or says my backup is corrupted.

I pressed 'X' during a backup after it froze during an update to software 4.3.5 and now it won't let me backup on my computer. Does anyone have any ideas? It either freezes during backup or says my 'backup is corrupted' or 'I cannot backup on my computer'. I have had to abort quite a few attempted backups since the initial problem, which I think has made it worse. I have already tried restoring my ipod, deleting the aborted backup from my preferences/devices in itunes and deleting it from my user/appdata/etc on my PC hard drive. Any ideas what to try next?

After hours of frustration I eventually decided to restore. I lost my apps, but i didn't have many and was able to reinstall them for free. During the restore it updated my ipod to the latest software 4.3.5, which i think may have caused the initial problem, but the backup issue remains. Sometimes it stops me from syncing and other times it allows me to skip the backup, but still says that i can't backup on my computer. I'm worried that it has done something to my computer as it took me six hours to do a Bullguard scan, which only normally takes about an hour. The scan didn't come up with any viruses, but it stalled at system32 for ages. The only other thing that i can think of is that a demo CD I uploaded may have caused a problem. iTunes couldn't find a track listing for it but gave me a few different options. i thought I had to choose one to continue, so did that then changed the track details to the correct tracks. I'm now worried that may have introduced an issue or caused a glitch in iTunes. How paranoid am I sounding?

Ipod won't backup or install version 4.2

Please help!
My IPod is version 3.1.3. I haven't backed it up/synced since October of last year. I wanted to upgrade it to 4.2 so I can use some of the new apps.
I started the backup and it took about 30 hours. It completed and the sync completed.
I tried to upgrade to 4.2, and it started the backup again. After 6 hours, it got to about 2 bars.
I've deleted some of the apps to try and clean it up, but it didn't have any impact.
I have another IPod (on another computer) and it works fine.
Any thoughts on how to fix this? Any help would be appreciated.
The IPod was purchased in 2010. It's a 3rd gen 8 gig.

Ops you are correct.
I have a backup, but it took 30 hours to complete. I am connecting directly to the pc using the usb port. I do not have another computer to try and sync it too.
I was going to try the restore and then backup the data into the itouch, but I'm concerned about losing all the data.
The other itouch on an older computer does not have any issues.
Is it possible to run 2 different ipod touches on a computer?
Thanks for any help. Very annoying.

My ipod won't sync any of the music i downloaded and says that iTunes can't backup the Ipod because a session couldn't be started with the Ipod how do i fix this

My ipod won't sync any thing in my iTunes library it always stop as soon as it starts backingup the Ipod a message appears that says iTunes cannot backup the Ipod "my Ipod" because a session couldn't be started withthe Ipod how do i fix this problem?
This is exactly what the message says: iTunes could not back up the iPod "austins ipod" because a session could not be started with the iPod.

Try connecting your ipod to another computer and sync only 1 file or song just for isolation purpose only to see if it'll sync.
If still not syncing, then porbably you may have a bad iOS installed in iPod which is hard to see if it has a problem because you said nothing's wrong with iPod. I just saying is, it MIGHT have a bad iOS.
If you are unable to do a restore, put your ipod in DFU mode, then connect to iTunes and iTunes will detect your ipod in restore mode. Press shift key (PC keyboard) then click the restore button on iTunes. I hope you have your copy of IPSW file for restoration purposes.

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.

To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

Moved my entire iTunes library to a new PC laptop from an old PC - iPod won't sync

I recieved a new Dell PC laptop for graduation and wanted to add my normal iTunes library from my old PC desktop. I moved my entire iTunes folder via a 16G flashdrive (in pieces, but accurately - the folder is 43G) to the laptop, and my up-to-date library was restored, play count and all. However, I decided to test out my iPod with the library, which should be the exact same library as before, by syncing a new song to the device. I plugged in my iPod to the computer, which iTunes recognized and acted as though it were syncing, but when I checked my iPod, the song did not show up on the device. It shows up in my iTunes library, but I can't figure out why iTunes won't sync with the device. I made sure that I moved EVERYTHING in the iTunes folder, so it should be recognizing the library as the same exact one as before. Help?!

You can only sync with one iTunes library. To change syncing libraries:
- Connect the iPod to your computer and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup.
Note that the backup that iTunes makes does not included synced media like apps and music.

IPod won't work when iTrip is connect to car charger

When I connect my itrip to the car cigarette lighter the iPod won't work, i.e. it will plsay the current tune but the controls don't respond and it stops playing when the current tune ends. It works ok when I disconnect the power.
Ipod model M9244B version 2.3
Any ideas?

Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Unsync all music and resync
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem that indicates a hadware problem, likely a bad battery. Make an appointment at the Genius Bar of an Apple store.

My ipod won't sync. keeps coming up with error message saying ' itunes could not back up ipod because a session could not be started with the ipod' help?

My ipod won't sync to my itunes. Keeps coming up with the error message 'itunes can not back up the ipod because a session could not be started with the ipod? it has been coming up with this message for the lst 2 weeks now. Will let me charge it but won't let me sync anything. Really not sure what to do or where to start or anything!

Follow these instructions to completely remove Apple software
http://support.apple.com/kb/HT1923
Then use free Ccleaner to repeatly repair your registry until it's fixed.
http://www.piriform.com/ccleaner/download/standard
download iTunes again from Apple.
http://www.apple.com/itunes/
If you have 64bit Vista or Windows 7, look for the seperate download of iTunes for that further down the page.
Once installed, use the Apple Software Update under your Start Menu to fully update all Apple components.
Your content will remain on the drive in the Music > iTunes Folder, nothing is deleted.
You should be making backups of your content regularly, either through iTunes or via copying the iTunesFolder in your Music folder to a external drive.

My ipod won't open the apps when i click on them?

My ipod won't open the apps when i click on them, i've restarted my ipod multiple of time, closed everything that's open, and they are still not working, but i get the notifications through, please help!

Try downloading and installing another free app from the App Store. This has resolved the issue for a number of users. Otherwise, you may need to try and restore your iPod from a previous backup via iTunes.

My Ipod won't transfer purchases.

My Ipod won't transfer purchases. I've tried all of the options to do so, but I click it and it doesn't do anything

Point 2 might still be applicable, it explains finding which file is causing the problem.
"Watch the display at the top of the iTunes window while your iPod is being updated. The name of the problematic file should appear in the display right before the error appears"
If the file is corrupted in some way you'll most likely have to put the iPod in Manual mode and delete it unfortunately. Further down in the article is this passage "To prevent future issues, you should delete the unusable files, then restore them from a backup". The problem then might be do you have a back up or not?

IPod won't connect after 2 weeks of working perfect

After using my iPod for a couple of weeks with no problems, all of a sudden, it does not connect when I plug it into the dock. It will charge, but the "Do not Disconnect" logo does not come on and iTunes won't recognize it.
I definitely have the newest software on the iPod. I even downloaded iTunes again, even though I already had the up to date version. I am using the iPod Video on Windows with the Universal Dock. This is my fourth iPod so I am not a total newby. I have tried all of the normal fixes.
I have tried three different connection cables with the same results. The kicker is that my iPod Nano connects and works perfectly sitting in its dock right next to the iPod Video.
If anyone has had this problem or has any ideas please let me know.
I have reset the iPod more times than I can count.
iPod updater does not recognize it. "Please plug in an iPod to update it" is all that I get from that.
I have connected the iPod directly to my PC using three different cables (all of which work fine with my Nano).
The iPod is showing as a USB Mass Storage Device in XP's device manager.
The iPod DOES charge while in the dock.
Thanks, Rick

Without knowing which iPod model, Operating Systems, USB or Firewire and other specifics everyone has, it's hard to isolate what exactly the problem may be. I don't think all of you are having the exact same problem, but maybe you are.
Richard, looks like you covered all the bases. Here are a few more things, if you haven't tried. If your Nano and Video are both connected, it could cause problems. I saw a post awhile ago about a guy who's problems went away when he only connected one iPod. Actually, it's best to disconnect all USB devices you can while trouble-shooting, especially if they are a USB storage device. You mentioned trying different cables, what about different USB ports? You mention that the "Do not Disconnet" logo does not appear, but the device manager sees a USB Mass Storage Device. I'm not sure if that's possible, that the Do Not Disconnect will not appear, but it is being recognized by the device manager. Is the device manager seeing a different Storage Device? ...or is that what's happening? Maybe it's time for Steven's option #4. Here's a few more ideas for everyone.
-Make sure the iPod is charged, charging for 4 hours will do it. Some USB ports are not high-powered ports and won't charge an iPod.
-Reset and Restore do different things. Reset mostly resets back to factory settings and calibrates the keys (don't touch any keys while it is calibrating), and you should not loose any data on the iPod. Resets are mostly done by holding down key combinations on the iPod and different iPods have different key combonations, make sure you are resetting for the iPod you have. If the iPod won't reset (comes up with Exclamation Folder, Frozen, etc...), mostly likely will have to be serviced.
-Uninstall iTunes, iPod. This means completely uninstalling. There are some folders that may have settings stored in them that are not removed when uninstalling iTunes. Remove them also; http://docs.info.apple.com/article.html?artnum=93698. Restart the computer between uninstalling and reinstalling, especially if using Windows.
-Update the iPod. Download the latest version of Updater for your Operating System, there is one for MAC and one for Windows. Updater is also where you will Restore your iPod; http://docs.info.apple.com/article.html?artnum=60944
-Restore will erase all the data on the iPod (have backups of the data, it can't be recovered from the iPod) and restore it's factory settings (disable disk mode, etc). Restore is done from the Updater program. Here is information on restoring; http://docs.info.apple.com/article.html?artnum=60983.
-Check the system requirements for your iPod model. Win XP (Home and Pro) usually needs Service Packs (SP) 1 and 2. Some iPods will work with only SP1, but it's best to have both. Win 2K requires SP 4.
-Try getting updates for your computer, especially if you are using PCI cards for USB or Firewire.
-Isolate the iPod. Disconnect other USB devices, especially if they are storage devices. Stop any programs that might be running in the background, disable virus software...3rd party software can interfere.
-Some Toshiba notebooks with the VIA chipset "will not work" with iPods. Hopefully you have access to another computer.
The following article might help. "iPod appears in Windows Explorer but does not appear in iTunes"; http://docs.info.apple.com/article.html?artnum=93716.
I'm interested in what everyone finds out. Good luck.

My iPod won't let me delete certain songs from the device

I'm not sure why, but there are certain songs that I've bought that my iPod won't let me delete. You know when you swipe over the song and red delete button shows up? That just isn't happening for certain songs on my iPod and I can't figure out why. There's probably a simple solution hut I'm not exactly great when it comes to technology so I'd really appreciate it I any one could help me out!
