Question: WD External drive won't mount

Hello everyone! I haven't been here in a while because I just haven't had any Mac issues. Now I do.


I have a 1 TB WD external HD that won't mount. I connect it via firewire to an Old G4 Sawtooth running OS 10.5.8. My mac sees the drive, it just won't mount. I've also tried to mount it via USB, but again, my system sees the drive, but won't mount it. I inadvertantly disconnected the firewire cable, which I didn't realize for several hours. I reattached the cable, tried to mount it, and nothing. I ran disc repairs, and Disc Utility actually told me the drive was successfully repaired. Again I tried to remount it, but nothing. I repaired permissions, and this didn't work. I've tried different cables, and this doesn't work.


I don't have another Mac to connect it to, so I don't know if this would work. Here's where things get a little wierd, but interesting. I connected it to my PC laptop, and it mounted. Now, this is a drive that was formatted Mac OS Extended (Journaled) on my G4, so I have to use Mac Drive so my PC will recognize and mount The Drive. So My PC sees The Drive as Mac OS Extended, and mounts it. All files are in tact, and the drive runs normally. This is a music drive and it plays normally on my PC. Meanwhile, if I try connecting it back on My Mac, the name of The Drive randomly changes from 931.5 GB WD to 931.5 GB WD My Media Book. I believe My Media Book is the factory name of The Drive before OS formatting. The Volume name remains the same on my G4 each time I've tried to mount it.


I do have another identical drive that mounts from all the bus ports on my G4. Any ideas here? Can I get my Drive to begin mounting on my G4 again? Any and all answers are appreciated.

Sawtooth G4; 1.8 GHz Dual 7447A; Radeon 9800/128MB; 2GB Ram, Mac OS X (10.4.11), Seagate 200 & 500GB HD; WD 120GB HD; Lacie DVD±RW; 550 Watt PSU

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.


PHEW!!


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.

Hi, I assume you were trying to mount it in Disk Utility by highlighting it & clicking on the Mount icon above?


In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)


Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.


Does it show there?

Hmm, interesting that you think the PC changed the drive. How could it change the directory, or mapping w/o initializing the drive, and wiping out all the data?


I'm heading out for the day, so I can't try the terminal mount 'til later tonight. Perhaps that will work. Of course, I'm terminal ignorant, so unless someone tells me exactly how to write the command, I'm usually at a loss. But, I'm willing to try.


The other option is to try mounting the drive on another Mac.


Thanks for now BDAqua.

I need a little help with the terminal command.


I think I need to use this command: diskutil mountDisk MountPoint|DiskIdentifier|DeviceNode.


I know the MountPoint is the Drive's Volume Name. In this case 1TB Music Drive. I think I found the DiskIdentifier thru Disk Utility, by highlighting the Volume name and clicking on Info. Disk Identifier is clearly at the top. But where do I find the DeviceNode? In Info under Device Tree there is a node@ with a number: is this it? I tried it in terminal w/o success.


Also, should I just use the command mountDisk and omit diskutil? Not sure here. Or is there another command I should be using?


Thanks.

Hi!


I've tried the two ways you mention. All that happens when you type that into terminal is you are given a list of ways to mount or eject a disc with possible command forms....I think?


It seems that the command I listed above is what will work. I just need to know where to find the device node, and how exactly to type the command.


Thanks!

I've discovered in disc info thru terminal that the external hard drive that won't mount has Owners: Disabled. All my other drives have Owners: Enabled. So when I enter the command to mount my hard drive thru terminal I'm told, "permission denied." I've tried to enable ownership thru terminal, but I just don't know the right commands.


So I'm wondering, if I can enable ownership for said drive, will I be able to mount it thru terminal? Can I enable ownership of of a hard drive that won't mount thru terminal?


Thanks.

Good work! 🙂


Open Terminal and type these commands carefully with the spaces & change 320GB HD to the name of your drive.


sudo chflags 0 "/volumes/320GB HD"

sudo chown root "/volumes/320GB HD"

sudo chmod 1775 "/volumes/320GB HD"

sudo -k

Hello again,


And thank you for all your patience and help BDAqua.


I typed in the first command: sudo chflags "/volumes/1TB Music Drive", and terminal tells me there is no such fule or directory.


Just to remind you, Disk Utility sees the drive, and the volume name, and I can access info on the drive thru terminal. So I guess the question remains: can I enable ownership on a drive that won't mount, and isn't mounted?


Thank you

Two more things I've noticed thru Disk Utility information. First, the unmountable drive is not showing up in the IODeviceTree. All my other drives show up there. Second, and finally, the unmountable drive has Journaled: No. Though it does show itself as Mac OS Extended (Journaled). All my other drives have Journaled: Yes.

I've read that WD uses crappy chipsets in their external drives. I'm wondering if the chipset is suspect here? Just not sure. I did discover that I can clone the drive from my PC as an exact Mac OS Extended (Journaled) drive, and my Mac doesn't even know the difference. I've also read that I can initialize the drive, and reinsert the drivers, and the drive should function normally. Interesting, huh? Well, let me know what you come up with BDAqua. And again, many, many thanks.

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...
