Ever since updating my kernel I've been unable to mount my 5th generation Ipod Nano. I can mount it perfectly using kernel 2.6.32-r29. I've been unable to mount it using kernels with version 2.6.38-r6 and above. My current kernel is 3.0.6. dmesg after plugging in nano: [ 84.299497] scsi 2:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 84.299773] sd 2:0:0:0: Attached scsi generic sg1 type 0 [ 84.304006] sd 2:0:0:0: [sdb] Spinning up disk....ready [ 85.808462] sd 2:0:0:0: [sdb] 1946049 4096-byte logical blocks: (7.97 GB/7.42 GiB) [ 85.809019] sd 2:0:0:0: [sdb] Write Protect is off [ 85.809019] sd 2:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 85.810020] sd 2:0:0:0: [sdb] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [ 85.811461] sd 2:0:0:0: [sdb] 1946049 4096-byte logical blocks: (7.97 GB/7.42 GiB) [ 85.833449] sdb: [mac] sdb1 sdb2 [ 85.835016] sd 2:0:0:0: [sdb] 1946049 4096-byte logical blocks: (7.97 GB/7.42 GiB) [ 85.837012] sd 2:0:0:0: [sdb] Attached SCSI removable disk [ 87.060697] sd 2:0:0:0: [sdb] Bad block number requested [ 87.060697] hfs: unable to find HFS+ superblock Dmesg after mounting: [ 91.903154] sd 2:0:0:0: [sdb] Bad block number requested [ 91.903154] hfs: unable to find HFS+ superblock Error message after "mount /mnt/nano" mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I have enable the necessary support for HFS/(plus) in the kernel: CONFIG_HFS_FS=y CONFIG_HFSPLUS_FS=y CONFIG_MAC_PARTITION=y Entry in /etc/fstab: /dev/nano /mnt/nano hfsplus noauto,rw,user 0 0 Reproducible: Always Steps to Reproduce: 1.Plug in Ipod Nano. 2.Mount with the "mount /mnt/nano" command Actual Results: mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so (Dmesg error messages have been shown above) Expected Results: Ipod should be able to be mounted without any error messages.

I cannot reproduce this with gentoo-sources-3.0.6. I formatted a flash disk using Disk Util in Mac OS Snow Leopard, booted into linux and mounted the filesystem successfully. I can also mount my local Mac OS partition. If you have a Mac OS installation, can you try this: # diskutil info <disk> where <disk> is possibly something like /dev/disk1s2. Can you try mounting it without referring to fstab like this: # mount -t hfsplus /dev/sdb2 /mnt/floopy One more question: Is /dev/nano a udev rule?
1. Sorry, I don't have a MAC OS. The only time I used disk util was when I first bought the nano when I used it to disable journalling for the nano. 2. I've tried: mount -t hfsplus /dev/sdb2 /mnt/nano with the same result (After disabling my udev rule): mount: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so 3. Yes, /dev/nano is a udev rule which reads as follows: SUBSYSTEM=="block", ATTRS{serial}=="000A27001D03B23A" KERNEL=="sd?2", SYMLINK="nano", RUN+="/sbin/fsck.hfsplus -r /dev/nano" 4. Some users had the same problem like mine with the Ubuntu system. A bug was filed here: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/734883 Could it be the same problem?
The corresponding LKML discussion points to: http://lkml.org/lkml/2011/5/25/248 This is fixed in 3.1: commit 6596528e391ad978a6a120142cba97a1d7324cb6 Author: Seth Forshee <seth.forshee@canonical.com> Date: Mon Jul 18 08:06:23 2011 -0700 hfsplus: ensure bio requests are not smaller than the hardware sectors Currently all bio requests are 512 bytes, which may fail for media whose physical sector size is larger than this. Ensure these requests are not smaller than the block device logical block size. BugLink: http://bugs.launchpad.net/bugs/734883 Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Can you try any of the >=sys-kernel/gentoo-sources-3.1.0 to confirm this?
Hello! I've just compiled kernel 3.1.6-gentoo and would like to confirm that this problem has indeed been solved. I don't get anymore errors and am able to mount my ipod correct. Thanks a lot for the follow-ups.
