Bug 212066

We only load drivers for devices that seem to be there -- thus, if there's no
usb-storage plugged in, we don't load it.

What does the output of print from parted on the ipod show?

But it's not possible to load the driver afterwards, and I needed to reboot to
get the iPod recognised.

Smells like a bug in parted.

Reassigning to parted on the basis of comment #2.  Looks like if parted
recognizes this partition table, we at least won't offer to reformat it.  We may
still offer it as a device to install to, though.

What kind of disk label is on the iPod?  Is it DOS or Mac?  The first partition
is probably throwing off parted's label detection code because of the id 0
partition that's listed first.

I don't have an iPod, so I'm not sure how I can recreate this problem.  Can you
give me a dd image of the entire contents of /dev/sdb (your iPod)?  That would
be most helpful.

Thanks.

That's the partition used to install new firmwares (dd the firmware to it,
unplug and restart the iPod).

It's a 30 GB iPod, so I'm not sure that would be the best. I'll get a dd of the
first partition and first bits of the second one instead.

I could reproduce the problem with parted with this disk image. I admit I
didn't test with a more recent version of Fedora.

Still a problem in F8.

Doesn't work on rawhide either.

patch to check for ipod partitions.

Tested with parted on git and it doesn't work on that either :)  There is a
patch on the mailing list (somewhere), that was also discussed with Eren on the
#parted channel.  It seems to work for the detection of the ipod partition (or
at least in my test and on Erens test as well)

Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:

Bastien:

Where you able to test this patch?

Can't really use this in fedora devel as the code there is from parted 1.8.8 (latest upstream release), not master.  discussion is ongoing in upstream, not a lot of attention though.

Seems to work as expected now.
