[solved] ipod hfs + archck + usb

Hi,

I have an ipod that strangly refuse to be formated in FAT32 (write disk error when I try to format it) but works well using a mac.

I'am currently trying to use it with arch. Since i've read on this forum that some user managed to get it working with an archck kernel ("Mine came formatted as HFS+ and I use it fine with ArchCK"), i switched to archck (using a tutorial on the french archlinux wiki) without any problem (i'am currently using it).

Of course i compiled hfs support as a module while compiling archck with abs and did a "modprobe hfsplus" before plug in the ipod (its the only modification i made to the kernel config, the rest is the generic config).

But I still can't get my ipod to work, here is dmesg when i plug it :

There isn't anything that show up in /dev exept "sda". I tried using another usb port but it didn't changed anything.

(fdisk can't read the ipod too...)

# fdisk /dev/sda

Unable to read /dev/sda

And i repeat, the ipod works perfectly with a mac, even after this dmesg output.

Any ideas? thx.

Re: [solved] ipod hfs + archck + usb

Does the ipod work fine with a regular ArchCK kernel from testing? (testing/kernel26archck)

If it doesnt, I'd say the ipod is bust and you should get another one while its in warranty... The fact that it refuses to be reformatted, and spits out disk errors isnt good.

Re: [solved] ipod hfs + archck + usb

damn, this ipod is just out-of-the-box (it come from an apple center, i already change my ipod twice in 9 months).

i'll activate testing and install kernel26archck.

Re: [solved] ipod hfs + archck + usb

Well, here are some news.

I installed and rebooted with kernel26archck... the ipod didn't work too.

But i managed to read the partition content with parted.

[root@tux max]# parted /dev/sda
GNU Parted 1.6.25.1

We use /dev/sda
(parted) p
Disk geometry for /dev/sda: 0kB - 20GB
Disk label type: mac
Minor    Start       End     Filesystem  Name                  Flags
1          1kB         32kb                   partition map
2          32kB       34MB                  firmware
3         34MB      20GB    hfs+              disk
(parted)

So parted reads it whereas fdisk can't (as i said and as you see, the ipod is empty, i just tryied to use it with both a mac and arch... and it just come out of the box). I read over internet that parted "is better" than fdisk because it try to read the partition table by its own and so can even read an mac partition map if the kernel as not been compiled to...

I'll try once again with a custom kernel and some others options
(CONFIG_MAC_PARTITION, CONFIG_MSDOS_PARTITION, CONFIG_SCSI_MULTI_LUN). (i've read on internet that even if the ipod is formated by a mac (and so use a mac partition map), you need to have the support for msdos partition otherwise it doesn't work. how can i see the config for the archck kernel i just installed from testing?) Thank you for helping me.

Re: [solved] ipod hfs + archck + usb

I had the same problem. It's some kind of conflict with module "ehci_hcd"

modify /etc/rc.conf add ehci_hcd to your MOD_BLACKLIST()

maybe there has been some changes now and you need to add !ehci_hcd to your MODULES()

I can't remember which that early in the morning.

Hope that helps.

Edit: Hmmm.. after all i'm not at all sure anymore hehe. good luck anyway

Re: [solved] ipod hfs + archck + usb

It finally worked out !

The errors messages and the especially long time to scan the device were due to a conflict with "ehci_hcd".

The non-recognition of the partitions was due to the absence in the kernel of CONFIG_MSDOS_PARTITION and CONFIG_MAC_PARTITION (and its not a rumor, i tested without the "msdos", you DO need CONFIG_MSDOS_PARTITION even if you don't have any).
