    Have you tried going to Disk Utility and seeing if it's listed there? If so, just mount it from there.

    Have you tried refreshing the devices and volumes page of the Apple System Profiler? Maybe that'll force it to show up on your bus.

    you could remove the cable and then reconnect it... you wont have to power off the device but you will still have to do something ITRW

    If you aren't averse to messing with the Terminal, I bet you could do something with the mount command.



    I'm not at my OS X box right now, but I'll try playing with this once I am there. I would imagine that your HD might still be listed under /Volumes/hd_name, but it might vanish from there once you unmount it... if it is still listed, I would imagine just a simple 'mount /Volumes/hd_name' would work.



    I'll try it later on this afternoon.



    By the way, what the heck does ITRW mean, Paul?

    /Volume/name is just a folder, when a disk is connected, a folder is created and the device is then mounted, which means that its filesystem is mapped into that folder. When you eject a disk, the volume is unmounted and then the folder in /Volume deleted. So, the folder will probably not be there anymore, however, you can just create one yourself.



    But you then still have to mount the drive (and I have absolutely no idea about external drives in OS X, it would be /dev/sdaX in linux). But you can try: find out which device it is in /dev (type "mount" when it is attached and visible in the finder, you should see something next to the /Volume/name string), then eject the drive and type "sudo mount /dev/the_thing_from_above /Volumes/afolder_that_you_have_created_before", might work. This only works if the firewire driver isn't unloaded when the disk is ejected, I think it isn't, though (as for example the samba kext isn't unloaded either when you disconnect and causes all sorts of lock ups and kernel panics later).



    I'm sitting on a beige g3 with OS9 and only remote access to my G4 with no external drives attached. I only had moderate success as the machine is not responding anymore, possibly a kernel panic (file system stuff is really poorly implemented, was fiddling around wirh the mount_ftp command, so it's not directly related to your problem, still it is annoying. Also: Apple should really clean up their man pages, most of them are outdated or don't exist at all).

    "automount" from the Terminal would work too, if you just want to mount whatever powered-on drives you have.

    Is this your internal HD? you might get it back by relaunching the Finder, I haven't tried it yet, but worth a shot.
