Almost all songs deleted from iPhone after plugging into computer

I've been playing songs from my iPhone through iTunes on different machines for years without any problems but as soon as i updated to iOS7 this issue has occured with no fix?!

What you do to listen to music will work as long as you don't sync the phone with the alternate computer or restore or update iOS (which forces a sync). You need to go to iTunes Preferences on the computer, Devices pane, and check "Prevent iPods, iPhones and iPads from syncing automatically". Once you have done this yu can play the iPhone's music through the computer without it erasing your content.

As pointed out earlier, iTunes warns you about this every time you connect, unless you click to not be notified.

I fail to see how this is related to iOS 7, since we both have had this problem since upgrading to iOS 7.

Our problem is not just syncing among computers, it's the fact that, even on the main computer (the one with which we initially set up the iPhone), adding songs to any playlist will leave the songs disabled, uncopied, with a dotted circle in the leftmost column, and this state remains unless/until we click on “Sync”, for a manual syncing (then, all apps are also re-synced). In short, automatic syncing of added tracks is broken.

And this seems to affect only a subset of users, so there's something special happening.

I've checked the box, gone through all the settings on phone and iTunes and it still keeps happening...?

I don't keep much music on the company machines in work which is why i tend to play through iTunes, i know i can just plug phone into computer to charge without launching iTunes and just play music through the phone, as normal, but its a little fustrating when i this used to work without any sync problems pre iOS7.

things are getting a bit WINDOWS with all these bugs for my liking...!

😕

You cannot sync iPhone with multiple computers, period. But that's not what this thread is about anyway, it is about plugging in to a different computer for playback purposes only, not syncing.

That also is an entirely different issue than what this thread is about. That concern belongs in a separate thread, where you will very likely get help to resolve that particular issue.

I normally auto-sync, but just for kicks I changed to manual management back home and connected to my iPhone at work. I as able to play my iPhone's music through my work PC just fine, with no deleted music when I returned home and connected back to my main computer (at which point I went back to auto-sync mode).

One thing that may be a factor is that there are actually two places where you can prevent automatic initiation of syncing -- there's the setting you showed above (which is a global setting for any device connecting to that particular library), and there is a device-specific setting on the summary page for the device (where you set your sync options, etc.)

It looks like you set the global iTunes setting correctly to prevent a sync, but did you do that on work computer, or your "home" computer? It would need to be done on your work computer for sure.

You might also look at the device-specific setting while connected to your home computer. The "Automatically sync when this iPhone is connected" should be un-checked if you want to ensure that syncing doesn't start when you connect to another library (in case the other library does not have the global setting enabled).

Verify those things, because I'm on iOS 7.0.6 and have no trouble at all connecting to my work computer and playing music through it, without getting music deleted. My work PC by the way is not using a copy of my home library file as I had suggested above.

The iPhone is meant to only connect to one computer, even if you manually manage your music on the iPhone. Connecting to another computer will delete music, surely there was a warning when you first connected your iPhone to a new computer.

I need to correct/clarify my statement above:

You can connect an iPhone to multiple libraries and not get music deleted from the iPhone, provided that you have the appropriate sync settings to prevent automatic initiation of syncing (which is not the same as "auto-sync").

What you cannot do is sync an iPhone to multiple libraries, nor manually drag music to the iPhone from multiple libraries even if your iPhone is set to manage music manually.

HELP ME PLEASE. Why everytime i disconnect my iPod (5thgen) from itunes the music is gone? but when I plugged it again all of my music are there. My question is how to keep songs in itunes even if my iPod is unplugged? When my pc is still on Windows XP, the songs in my itunes is there even if my ipod is not connected but. now Im having a windows 7 and i re-install the itunes and my music is not there if I didn't connect my ipod 😟

Your problem has ZERO to do with the subject of this thread. If you would like help with it create a new message describing your issue in detail.
