that used to happen with the old iTunes to me. I have a 3G iPod, but i haven't had that problem in a while now.

didn't that guy know that you can't talk against apple on this site?
hey you stupid *%&#?, go buy a dell if you're not happy

Stwike him, centuwian!

So out of however many millions of iPods that have been sold, "dozens" have this problem?

Doesn't sound like a "problem" to me. How many of these people have run diagnostic software to check for and repair disk errors?

If your iPod cannot be used as an external hard drive, that sounds more like a disk error than an iTunes 4.5 problem. Almost every time I've had problems with my iPod, DiskWarrior fixed the problems. On only one occasion did I have to do a complete reset with the iPod utility.

Before blaming Apple, how about trying to fix the problem yourself? If it IS a serious falw in the software, fine. But do some diagnostics first and make sure it's not simple disk corruption.

I was actually experiencing this just this past weekend. My girlfriends Mini was acting every strange. It would show up on the desktop, but iTunes would sometimes not rec. Then, when I tried to update it, the updater says no iPod is attached, yet it is sitting their on the desktop.. Very strange...

try pluging it in again or restarting the computer. that usually fixes most problems i come across.... of course i leave mine on for days at a time...

I use a first generation iPod with iTunes 4.5 with no problems.

I had all kinds of problems, too, and picked up a fix on one of the other forums out there. As best I can recall, the solution is to delete ipodriver.kext in /System/Library/Extensions, download and reinstall iTunes (you can do a custom install to install only the driver), and restart. This fixed it for me - I have never had any further problems.

I would guess that sometimes the iTunes installer doesn't properly replace the driver file with the updated one.

OK. So did you run the disk utility to scan your iPod for errors? Have you run DiskWarrior?

If it's got a hard drive, it can be corrupted. It's happened to me many times. DW works 99.9% of the time in correcting even major errors, and that one .1% was the time I had to run the iPod restore software.

If you still can't fix it, is there an Apple store nearby, or do you have a friend with a Mac? Take it in and see if it'll mount on any of the machines there. Maybe the people there can give you some assistance as well.

Hope you get it working again!

I've had some problems with my iPod and iTunes, but I'm pretty sure it started happening before iTunes 4.5 (I think it may have started when I got a replacement iPod for my original one, which stopped playing or something). Basically, if I put my iBook to sleep when the iPod is connected and mounted, when I wake the computer, the iPod refuses to show on the desktop or display in iTunes. It shows up in Disk Utility, and I can mount/unmount it there, but that doesn't get it to show. If I go to /Volumes, it then shows on the desktop, but still a no show in iTunes. I have to restart to get this to work again (and it seems like if this occurs, I also can't see disk images on the desktop either).
