iPod I/O error and unmounts when trying to read files

Asked by Travis Larson on 2007-05-09

Just installed 7.04. Ubuntu mounts my iPod after I plug it into the USB port. There is a fancy iPod icon on the desktop. I can open up Nautilus and browse the files on the iPod. When I try to copy the files (or open directly from the iPod) to the home directory the file transfer errors out:

**********
"Error "I/O error" while copying "/media/NE...filename".

Would you like to continue?
Skip|Cancel|Retry
**********

At this time the iPod is automatically unmounted and the desktop icon disappears.

The iPod itself seems fine. I was able to connect it to my laptop (Win XP) and copy files to a thumbdrive. Any ideas?

Here are some log files that will hopefully help:

In which file system is your iPod in? In other words did you connect it first to a mac, windows or linux?

Travis Larson (tlarson) said : #2

The iPod is formatted FAT32. It was first connected to Windows.

Thanks!

Travis Larson (tlarson) said : #3

I've ruled out the possibility of the iPod being the problem. The same thing happens with a different iPod (same model).

Here's a really odd twist to this situation. The iPod works fine under the Live CD!!!!? What could be different between the Live CD and the actual install?

stvmty (stvmty) said : #4

Confirmed. Same problem here.

Xubuntu, 7.04 iPod Nano formatted FAT32.

Joachim Beckers (jbeckers) said : #5

this is a long standing issue (I've had this bug hit my ipod on and off since hoary). it's something that no one seems to want to/be able to fix.

the best workaround for now is to use usb 1.1 instead of usb 2.0 to access the ipod (to do that: sudo modprobe -r ehci-hcd).

also, if you're lucky: with some kernels, the issue does not arise. 2.6.20-13 was such a kernel (at least for me it worked ok)

Travis Larson (tlarson) said : #6

Joachim - Thanks for the information. I'll give usb 1.1 a try.

Also, just to clarify, I was incorrect when I said it worked fine with the LiveCD. I just tested it again and it failed.
