Q: Mavericks corrupts external hard drive

My WD MyBook studio 2TB (fw800) suddenly shows up empty on my desktop after a Mavericks upfrade on my mid 2009 mbp.

 

Disk Drill is now scanning the WD, and the files are there, about 1,4 TB of it...

 

How do I get the disc structure back?

 

I have no Mountain Lion OS-mac to test the WD in..

 

I had a bootable Mountain Lion on the WD, could that be the problem?

 

In Disk Drill MyBook has four units; EFI(200Mb), MyBook(1,8Tb), Unallocated 128Mb and Lost partition (200Mb)

iOS 7, Ipad mini + ios7

    Are these Apple Drives you are talking about?

     

    Apple doesn't make HD, never has.   WD, Hitachi, Seagate, Toshiba.

     

     

     

    Ahh, yes. I kind of knew that. But thanks for the info.

    petermac87 Well yes, maybe if you're wheel rims and your tires didn't work properly together and you spun off the road you might...

     

    I'm under no illusions here, and don't expect anything from Apple or WD to be honest, but between us users and consumers let's keep it constructive eh? Solidarity and all that...

    Yes I am going to complain to Mercedes about my displeasure with the Bridgestone tyres I am running on my car.

     

    Good luck with all that.

     

    Pete

    All to do with the context of the situation. Mercedes wouldn't recommend Bridgestone tyres for your mercedes but Apple did recommend my mybook studio drive and sold it to me.

    I think the mac part in the name shows where loyalties lie.

     

    Having a crack at people because they state they would like to see a statement posted from Apple on this situation is indeed, insulting. I have kept an eye on these posts and many people like myself have opened cases through apple care and received a non caring not our fault go see WD answer . In my case even the guy from apple was shocked at the dismisiveness of the Apple engineers.

    For me, the AppleCare staff was well aware of the issue when I called them and very much opened to collect as much details as possible from me, which I did by sending them loads of screenshots and logs. At the moment, my ticket is still "work in progress", ie not closed. I agree they're very quiet but I've been told they're dealing with WD on this issue.

    I however don't expect to receive a fix from Apple or WD to recover the partition table as far as my understanding of how file system is handled in OSX. That's the reason why my disk has been sent to and is currently under scrutiny with one of a preferred WD partner in data recovery.

    The lack of Apple feedback I was referring to was NOT on these forums. It was the lack of feedback to the people who actually go to the trouble to communicate with Apple by following the link you provided. And the lack of public feedback when Apple discovers a serious problem and allows their users to continue falling into the pit while they work on a fix.

     

    There is a reason Tim Cook's public admission of the flaw in Maps is so famous. Admitting flaws is simply not in Apples genes. It takes a public relations disaster like Maps to get Apple to admit anything was ever wrong with their products. New updates merely enhance Apple products (and fix a few bugs).

     

    I've been exclusively using Apple computers, smart phones and tablets for over  3 decades ( I still own an Apple ][e....) because I like Apple's products. But I find Apple's arrogance, with respect to communications about flaws in their products with their customers, to be mind numbingly stupid. While I'm pretty certain I won't  be able to cause Apple to change, I am absolutely certain I don't have to be an enabler/fanboi.

     

    It has been a decade since I last participated in the Apple Support Forums. I only returned with a new handle, so that I could post in this thread. My intention was to possibly help myself and other Apple users document/understand what I believe is a flaw in how Mavericks deals with ALL large external drives. If Apple wants to scan this thread for the info I've posted -- fine. But I will not go to the trouble to write this all up again, tie it in a bow and push it through Apple's one way feedback website slot.

    Do the math. There are many millions of users of Apple products. Over seven million of them have signed up to post to the discussions web site. There are thousands of new posts every day & dozens of different forums.

     

    With this in mind, do you really think it would be practical for Apple employees to monitor all this, or wade through long, multi-faceted rambling discussions like this one looking for something useful they could pass along to engineering that they don't already know about?

    Apple is no longer a David fighting Goliath. Apple's current cash hoard is around $150 BILLION. Do the math.  Apple could afford to hire quite a few people to improve their communications with their costumers (i.e. feedback to customers) about the problems they are aware of in their products BEFORE they release a patch and pretend it never happened.

    Well, as far as my issue with an external 3TB WD Red drive is concerned, I went through the whole reformatting and rewriting process again and this time the bad drive worked in the same enclosure that it failed in previously. I did look further into this on WD's website and they acknowledge there are rare circumstances that can cause this to happen between their drives (and other manufacturer's drives) and Mavericks. So I guess my reformat etc. didn't encounter those rare circumstances this time around. Weird.

     

    Also, as a fellow 3 decade user of Apple products, I completely agree with GetRealBro's comments about Apple's escalating arrogance but I also know that Apple do read these forums and heed what's going on. In the past I've provided very specific details about how to induce and fix a difficult to pin-down bug for my hardware and it tweaked their interest and an Apple engineer contacted me (citing my post). If Apple officially said they read the forums then they'd officially be exposed to more liability. It's a lawyer thing...

    Has anyone else noticed the WD uninstaller seems to create another launchd job…

    /Library/LaunchDaemons/com.westerndigital.WD-Software-Uninstaller.plist

     

    Which launches…

    /Library/PrivilegedHelperTools/com.westerndigital.WD-Software-Uninstaller

     

    When do we get to download the uninstaller's uninstaller?

    I eventually (thanks to this forum) found the WD software files in my Mac's Library. The WD software was not in my Apps folder and wasn't (or shouldn't have been) running at the time I plugged in the drive.

    Keep in mind that anything that requires entering an admin user name & password as part of its installation process may install one or more small software programs that constantly run quietly in the background. Some of these things, like the launch agents & launch daemons that have been mentioned earlier in this long topic, may do nothing other than run other software programs when they detect that certain events have occurred.

     

    This is the preferred method of implementing many system level functions & services because it doesn't use a lot of memory or CPU time when it isn't needed. Both Apple & third party software makers use this method. There is nothing new about it; it has been a standard, fully supported part of OS X as far back as 10.4 Tiger.

     

    When the OS is upgraded or reinstalled, unless users do a "clean" install by first erasing the drive, these third party items are preserved. If they were not, users would have to install them again. Likewise, migrating from an older Mac to a new one will migrate over to the new Mac many of these things, depending on the user choices made during the migration process.

     

    Because of this, & because most third party software doesn't make it obvious it might be installing anything besides an application, it is often true that users have some outdated stuff running in the background or triggered by various events, not all of which are user initiated. Often, this doesn't cause any problems at all, but sometimes when a new OS version is released these things no longer work as intended because, for example, they were coded to use an Apple-supplied system level framework that has been upgraded to support new features that didn't exist when the third party software was developed.

     

    Ideally, the third party developers discover & fix these problems long before the new OS is released (since most have prior access to the OS through Apple's developer program). But if the problems are subtle or occur only under certain conditions, they may not be detected until enough users are using the new OS to make it obvious there is a problem that needs fixing.

     

    It would be wonderful if this never happened but the reality is OS's are now so complex & there are so many of these third party add-ons users might install that is impossible to test everything, in part because the add-ons may behave normally by themselves but not in combination with others.

     

    For that reason it is important for users to know if any of these things are installed on their systems. Since that isn't easy, one of the ASC regulars wrote a small application called EtreCheck that automates the gathering of this & other info that can be very helpful when dealing with this & several other kinds of problems.

     

    Posting the results of EtreCheck is one of the best ways users can help discover the cause of problems like this one. Sometimes it becomes obvious that a third party add-on is the culprit, but just as important it can help show that this isn't true, that the problem must have some other cause, including a bug in the OS itself.

    To that end, may I suggest that you post the results of EtreCheck for your system?

     

    If more users did that, it would be much easier to see if (for instance) there are any remnants of the WD utilities or other third party add-ons that may be a contributing factor.

    Don't be too sure about that. Some of the users of these forums have developer accounts with Apple & submit bug reports that cite posts made here when they contain enough detailed info to help pin down some bug.

     

    Also, level 6 & above users have access to the "Lounge" forums with a little better access to the forum moderators & hosts. It isn't unusual for one of these users to request that the mods take a look at some discussion to see if they think it is something that should be passed on to Apple engineering.

     

    (In case you are wondering, we don't usually get any more feedback about if it was acted on than anybody else.)
