Re: multible partitions?

i just want to warn you: i recently trashed a 160gb lacie d2 firewire harddrive with linux (see: http://lists.debian.org/debian- powerpc/2005/05/msg00464.html). if you wan't to mount hfsplus on linux do it read-only for now...

Thanks for Your hint - are You a "single case" - or are there more such issues?

i hope this is a single case. however i posted this to a slighly older thread in which a person described a very similiar problem. i think the problem is the combination of kernel version, firewire driver. i am pretty shure that hfsplus is quite stable now, because i used it often with my internal volumes.

now to your problem:

mount /dev/sda1 -t hfsplus /hfs

you don't specify the right partition. you can read the partition- number from the output of macos disk utility below, from the "Medien-Identifikation" label: e.g. "disk2s10" means partition 10 on disk 2, which could map to /dev/sda10 on linux. alternatively you can run "fdisk -l /dev/sda" in linux which prints the partition table of /dev/sda.

Unluckily there is no output just running the command.
Inserting my USB stick, than removing it leads to results - but they are not so friendly. Here comes dmesg stuff - a left the lines related to usb and FireWire, maybe this is of some use. The external disk issue is at the very ending:

possibly you still don't specify the right disk/partition. the device node files are constructed like this: /dev/sdXY, where X is a disk character and Y is the partition number. if the usb-driver mounts a drive on /dev/sda it's possible that your firewire drive is in /dev/sdb.
