Hi all, I am running 3.2.5-gg987 and I am experiencing a problem mounting my 3TB HFS+ formatted drive. The drive has been used on a mac (and formatted there) for a long time. I just need RO access to it, so journaling shouldn't be an issue. Regardless of my mount attempts it errors with: [681648.160023] hfs: invalid secondary volume header [681648.160026] hfs: unable to find HFS+ superblock Here's the drive info: $ sudo parted /dev/sdb unit B print Model: ATA WDC WD30EZRX-00D (scsi) Disk /dev/sdb: 3000592982016B Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 20480B 209735679B 209715200B fat32 EFI System Partition boot 2 209735680B 3000458743807B 3000249008128B hfs+ 3TB-Backup Things I've tried: Direct mount: sudo mount -t hfsplus /dev/sdb2 /testmnt Offset mount: sudo mount -t hfsplus -o ro,loop,offset=209735680 /dev/sdb /testmnt Manual loop device offset mount: sudo losetup -f /dev/sdb --offset 209735680 --sizelimit 3000249008128 --show sudo mount -t hfsplus -o loop,force,ro /dev/loop0 /testmnt Manual loop device direct mount: sudo losetup /dev/sdb2 --offset 0 --sizelimit 3000249008128 --show sudo mount -t hfsplus -o loop,force,ro /dev/loop0 /testmnt None of this works. For what it's worth, the block headers are per HFS+ specification in the right place: $ sudo dd if=/dev/sdb2 bs=1024 skip=1 count=1|hd|head 00000000 48 2b 00 04 80 00 21 00 48 46 53 4a 00 00 15 d6 |H+....!.HFSJ....| 00000010 cd 0e 7c 22 cd 0f 0d 10 00 00 00 00 cd 0e 6e 12 |..|"..........n.| $ sudo dd if=/dev/sdb2 bs=1024 skip=$((3000249008128/1024-1)) count=1|hd|head 00000000 48 2b 00 04 80 00 21 00 31 30 2e 30 00 00 15 d6 |H+....!.10.0....| 00000010 cd 0e 7c 22 cd 0e 6e 12 00 00 00 00 cd 0e 6e 12 |..|"..n.......n.| Thanks, -fcpk/Paul-Kenji -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
