I suppose it could be the chipset or enclosure, but not all that likely is my pure guess.
One of these might answer that question...
In Info under Device Tree there is a node@ with a number: is this it?
Yes, looks like we have that now.
I wonder what this means?
What do working ones report there?
You think new cables might help? You could be right.
I'm not sure about the node question? But for-what-it's-worth, here is what I get under Device Tree: fwx/node@90a9c5c29aa50b/sbp-2@000/@0:10. I've no idea what this means. Some of the mount commands in Terminal require the DeviceNode which looks like this: /dev/disk4s10.
If you get info for the volume in disk utility it reports no, even for working volumes. If you get info for the drive in disk utility it reports yes. I would reason that it reports yes for the drive because it is the whole drive? I'm feeling pretty dopey here.
My sense about this case at this point is that when I inadvertently disconnected the firewire cable w/o ejecting the drive, it changed the status of ownership to disabled, and journaled to no. Who knows why? At this point I'm wondering if I can reinstall the drive software into the chipset w/o damaging the data on the drive? I've submitted this case to WD, but have not heard back from them yet.
I'm relieved that the drive works on my PC. If I can't get it to mount on my Mac, then all I have to do is purchase another drive, and clone the damaged music drive over to it. I won't cross this bridge until it seems definite that I cannot mount the drive to my Mac.
WD has issued a reply to me regarding the damaged drive. They say to "dump to contents into a drive on the computer that recognizes it, and reformat the damaged drive on the Mac." And that's that.
So, unless someone here comes up with solution, I guess that is what I will do.
Thanks everybody and especially to you BDAqua for the effort you gave.
I have this problem too with my Western Digital 1TB My Passport for Mac.
Downloaded Card Data Recovery - did not work. The software self terminated itself when the problematic WD is connected. Starts up fine when the WD is not connected by USB.
Then I downloaded Remo Recovery. Starts up fine, scans fine and appears to save the files but ALL the files 'saved' are unreadable.
Finally, downloaded Stellar Phoenix in a last ditch attempt to recover my precious video files. Starts fine, saves fine BUT it cannot save files above 200MB because the WD stops working every 10 minutes.So, did not solve my problem totally because I have so many files above 200MB.
And yes, I PAID for all the software above. And the first two software are reluctant to refund me my money until their development team can ascertain whether it's a software bug, over online web conference. And because of the time differences, I can never get online with them. So, all my money gone.
Until one day I opened Activity Monitor and noticed this 'fsck_hfs' starting up everytime I connected the problematic WD My Passport for Mac.
So, tried to Force Quit 'fsck_hfs' and VOILA!
A dialogue box popped up and says that the Passport for Mac cannot be repaired and that I can move and copy files from it but not save to it.
At least I can access the files and save them to my Seagate 1TB although now I am having a problem opening FCP X project files rescued from the WD.
I have the same basic problem BDAqua, but a different cause. I'm sure theres a simple remedy
I formatted an external hard drive from NTFS to HFS I think you say? ( Mac OS Journaled) using Disk Utility in Snow Leopard.
It all went fine, I loaded some files (this is a media player for television set) and that was that.
Now this media player has its own file system (Linux) giving me the ability to move files and folders around on the Hard drive, so I made the mistake of moving all hidden files ( /.DocumentRevisions-V100/, /.fseventsd/, /.Spotlight-V100/, /.TemporaryItems/ etc. to another folder so they were actually hidden; being on the Linux system and all
After trying to mount the drive on my macbook again it would not show up. I tried to put the hidden files back in the same place I got them but no luck. One thing I noticed is that somehow I had two /.Spotlight-V100/ folders, I know there should be only one and have tried mounting with either in the right location. No luck
Any help please?
Thank you thank you THANK YOU mdazlan76! I have been trying to get access to my GDrive Slim for hours and after running Disk Warrior and Stellar Phoenix Mac Data Recovery I almost gave up. I just so happened to stumble across this forum and I tried your suggestion and I IMMEDIATELY regained access to my external HD. Thanks again for your help, you seriously saved my day.
