Firewire Drive not mounting

I have searched on this topic and tried resetting the firewire bus as described in several topics with no luck. So I am thinking that my problem could be something else.
I have a Lacie120 firewire hard drive that is not mounting in Leopard. I see the drive in system profiler and in disk utility. Under the system profiler it shows all the information about the drive. The item I noticed that is missing is a mount point, threre is none. When I try and do a repair on this drive it fails. The error states "Invalid node structure" and "Invalid B-tree node size". This is the the log entry.

So I am wondering if my hard drive is now a brick. Any insight to this will be greatly appreciated.

It's not a brick, unless you don't want to spend more money.

If Disk Utility can't fix it, and it can't; this error is too serious, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy.The only problem,it is not totally Leopard ready yet. Soon, they say! Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.
I use DW once a month to try and catch errors in my system from getting too far out of hand.
An Erase and Install will also rid you of this issue. But, beware! You will lose everything on the drive with this procedure. Let us know if you need help with that!

Dale,

Thank you for your response. I do have a copy of DW ver 3.0. I wasn't able to use it under Leopard. I could not unlock the CD to uncheck "Ignore ownership of this volume" under get info. Don't know why. So I used my old G3 iBook which has 10.3. The rebuild from DW failed. So I had no choice to erase the drive and reformat. It now has a mount point and mounts in Leopard. The files that were lost were backed up on another drive, so all is not lost. What was lost I can recreate.
Thanks again.

Yes, you need to wait till Alsoft (makers of DiskWarrior) have their Leopard ready version. Version 3.0.3 cannot be used. They have a new one out now and you'll get a free upgrade to the Leopard version if you buy. The upgrade cost from 3.0.3 is $49.00 for the new version of DW. Then the Leopard update is free. DW's new version handles a lot more tasks now.
Good Luck!

I am having the same issues with my Acomdata 250 Gig external firewire drive. I can see it in the Disk Utility as well as the System Profiler. I have tried to mount through disk utility, but it won't mount.

I was wondering if I use the disk image tool in Disk Utility, can I save the data, mostly my music, and then erase the external drive, rebuild and then reinstall the data from the image? I'm keeping my fingers crossed. I don't want to lose my 25,000 songs.
