    I jacked in my external drive and I get a alias message error. Not sure what to do. Does you have this problem with your external drive?

    I have EXACTLY the same problem with my Western Digital My Book.

    Although it would appear we're the only ones on the net with it - or at least the only ones to report.

    I had a copy of the retail disk a week before release and the same problem persisted, ive just tried a new install again tonight from fresh in case something was corrupted in the process but no - as i booted up exactly the same thing.

    Unfortunatly that makes it unusable for me as the my book is mounted wirelessly and logins in everytime i boot OS X with all my media files attached...

    It must be a WD/MyBook/SL compatibility problem...

    akutad - I poked around a bit and found the answer.

    Download Path Finder 5. You'll be able to access your drive find - right click on it and chose get info.

    In there you see "alias bit" untick this box and suddenly the drive will work perfectly with Snow Leopard.

    Ive yet to try rebooting, mounting and unmounting etc but for now it works - its obviously not the answer if I have to do this ever time i reboot of course!

    Hope it helps though.

    I'm having this problem but with the WD as a wireless shared drive via my Airport Extreme. I wonder if it's related? My drive does mount via FW800.

    Just use my fix - it will work if its exactly the same problem you're having.

    Mine did the same if connected direct via USB or via Airport Extreme.

    Did you guys keep the drive connected while you did the install? I disconnected everything from my computer when I installed SL and when I reattached my WD Studio Book (thru firewire), it recognized it immediately.

    I dont think the first poster did no.

    And mine was connected via Airport Extreme - so it wasn't mounted properly during the install, either way, its a bug that shouldn't exist.

    WD MyBook Studio doesn't mound with SL

    I'm having the same problem (since installing SL my MyBook Studio 500Gig drive won't mount). I can't recall if it was plugged in during the SL install or not. The drive isn't found by the disk utility and isn't found by path finder 5. Any other advice would be appreciated.

    I had problems with my WD MyBook Studio 1TB after upgrading to SL. System profiler and disk utility wouldn't even recognize the drive connected let alone allow Time Machine to do the backups. Thought it might be a driver issue, and it turns out after several hours on the phone with Apple & WD that according to WD, the new drivers compatible with Snow Leopard require a dedicated power outlet from the wall and cannot be used on a power strip. As soon as i switched from the strip straight to the wall the drive loaded up just fine. Have never had issue with this before, as my external drive always worked like a charm in time machine connected to a power strip, but i guess that's not the case with snow leopard- hope this helps for some out there.

    I am, unfortunately, having the exact same issue.

    However, I can't imagine how the drive can "sense" when it is connected to a wall outlet versus a power strip. This really can't be the issue.

    I have to agree with you there....unless the wall outlet is putting out extra-special energized magical electrons that the power strip filters out :)

    dannys1 your pathfinder hack worked - thanks!!!.

    However the drive (WD 2TB in RAID0) will still not mount if connected via firewire. USB sees the drive with the alias bit on.

    What in snow leopard is causing this strange behavior ?? Will have to keep it connected via USB for now.

    RE: Pathfinder fix. The drive shows up in disk utility but not in Pathfinder. The utility won't let me do anything to it, and pathfinder doesn't even see it.

    It shows up in the disk utility when I connect it via USB, but that only seems willing to let me erase and re-format. It's giving me a number of reformatting options, anyone know which one I sould pick? Seems promising -- it's reporting the disk as unformatted.

    I'm having this very same problem with my 500 GB My Book and 1.66 GHz Core Duo Mac Mini. It worked perfectly fine over firewire before the upgrade and for a few days after the installation, until one day I went to start iPhoto, and I was told that my mac couldn't find the external hard drive on which my photos are stored. I've tried all of the fixes mentioned here, and nothing seems to work. I've tried USB instead, Path Finder, plugging the power cord directly into the wall, and now it's not even showing up when plugged into Windows computers via USB.

    Any other suggestions?

    different cord

    I tried everything, including the pathfinder option. My book was just not being detected. My solution was to just try a different usb cord that I had for one of my cameras and it worked immediately and I am able to back up again using time machine and access all my files on the my book. So try a different cord!!

    I am having a similar problem, where drives will just refuse to mount. Even some DMGs refuse to mount.

    WD Studio II Drive USB to Airport Extreme Will Not Mount in SL

    Hi everyone...

    Thank goodness that this forum exists; I didn't know what was going on with my 1Tb WD MyBook Studio II Drive.

    I have two external drives connected to my network via a USB hub to an Airport Extreme: a 1TB WD MyBook Studio II drive and a 1TB WD MyBook Premium II drive.

    I use ChronoSync 4 for periodic network backups from one WD MyBook drive to the other.

    I have routinely updated firmware on both these drives and both are up-to-date and all is working fine with OS 10.4 OS 10.5 and Windows XP.

    Upon installation of OS 10.6, I am unable to mount the 1TB MyBook Studio II drive; but the 1TB MyBook Premium II drive mounts just fine.

    What is surprising about this is that the WD Premium II drive is an earlier version of the MyBook Series drives!

    Judging from this forum, I suspect a firmware problem for the Studio II is the cause.

    I thought it helpful to post my issue so that others won't get unduly frustrated after spending needless time checking over network configurations, connections and settings.

    Bye for now...

    WD Studio II Drive USB to Airport Extreme Will Not Mount in SL

    Hi everyone...

    I've just received a reply from Western Digital Support regarding my WD Studio II Drive networking issue; confirming that firmware is to blame:

    "Thank you for contacting Western Digital Customer Service and Support. My name is N.V.

    I truly apologize for the inconvenience you are currently experiencing. At this time we are working in order to create the firmware update to make this unit compatible with Snow Leopard, unfortunately we do not have a release date yet. Please keep checking WD website for any news update.

    I hope that we have met your expectations today and that you are satisfied with our service. If you have any further questions, please reply to this email and we will be happy to assist you further."

    So I guess that I'll (we'll) just have to wait...

    Went through this all over again after reinstalling Snow Leopard after a hard drive replacement.

    After installing the WD Button Manager and rebooting the computer I unplugged BOTH the Firewire connection and the power to the drive.

    Wait 30 seconds before plugging in just the power to the drive.

    TURN ON the drive after plugging it in from the button on the front. It should now be lit up.

    Now you can plug in the Firewire cable to the drive. Do not plug the Firewire cable in until you have done everything else.

    Drive should appear and will work normally now upon reboot and such. Follow these steps again if the drive ever fails to appear again.

    This works for the MyBook Premium. Other versions may vary but it usually comes down to the drive uses power from both Firewire and wall outlet and needs to be completely powered down and brought back up in sequence.

    I hope this helps at least some of you out with this problem.

    Hard drive format

    Hi guys,
    Had the same problem with the WD My Book Home edition not mounting from Airport Extreme. It would show as shared in Airport Utility but you couldn't access it. I did the firmware update but still no success, then I remembered something to do with partitions. If you partition the drive (with 1 partition) and choose in the options to have GUID Partition Table, problem solved (for me anyhow). My drive was formatted Windows fat32 when I got it. As such it had the option "Master Boot Record" which I assume was preventing the drive from mounting.

    WD Studio 1TB Drive Won't Mount in Leopard

    I had the same issue on OS 10.5.8 (Leopard). I have two WD My Studio 1 TB drives that I rotate for Time Machine backup. I connect via FireWire 800. Time Machine stopped working and neither drive would mount.

    Solution: as mentioned earlier, the sequence to connect the drive.

    1: remove both the power cable and FW cable from the drive
    2: wait for the drive to spin down
    3: plug the power cable back in
    4: press the power button; you should see the light
    5: then connect the FW cable

    Now enjoying the quiet purr of a Time Machine backup. Bizarre issue. Thanks for the help, all.
