    You can scan this thread for other people having the same symptoms. I don't recollect anyone having a crash, so I suspect you may simply have damage from a disk left in a bad state. Don't forget it's possible that the disk iteslf caused the crash if it was damaged before the backup began. 


    If you have a bootable Mac OS before 10.9 use that to look at the disk. Others have reported issue with disks appearing in older OS's.


    It's possible the disk itself is failing or has been damaged. Backup the data once you can access it or if you have backups already consider using repair tools to look at fixing the disk.

    Drilldisk should tell you what can be recovered (before you buy).


    I have had success with Disk Warrior (but under different circumstances).


    There are also some free tools if you can use the Terminal?


    I don't think you have the same situation as the other posters here, but then again this thread is too long to remember everything. There are some hints on how to use recovery tools ealrier in this thread too.


    Also see my comment above about using Etrecheck to look for WD software - it doesn't help anything on 10.9.


    If you have no other choice you can use 10.9 to inspect the disk, but it's still unknown if it is at fault (and which of the many failures it causes).

    Basically I seem to have the same problem as everyone here. My external WD hard disks (3 different ones) fail everytime I wakes my MBPR 2013 from sleep. Tried to repair it but can't, here are the details:

    The only way to solve it is to attached it to my windows laptop and run the repair from there. I already tried reformatting my hard drives already (ExFAT formatted) but they are still giving me problem.


    Could anyone point me to a correct direction to solve this issue. I read through the threads, my problem seem to be milder but I just cant seem to get rid of it. Thank you in advance for any form of help.

    The messages you posted are the messages that Disk Utility issues when it tries to access a disk that is "busy" running a long fsck. While I was testing this bug in Disk Utility, the disk/partition always mounted correctly if I waited for several minutes for the longer fsck run to complete (8 min in my case).


    You can check to see if this is your issue by opening the Console and monitoring the /var/log/fsck_hfs log.


    IFAIK there is no know solution besides patience.

    The Bad News: As far as I know there is no know fix for these long fsck runs.


    At least I was able to narrow it down to a fsck issue a couple months ago.



    Now the rest is up to the coders in a resolution.

    Yes, as a "collector" of 100s of hard drives, and study of them, and constant updates on new / changes etc. you can be sure of two things:


    1. never buy consumer grade WD drives


    2. regardless of what you buy in hard drives, OR what you use it on PC or Mac,.....youre always in horrible danger with a single external copy of your data.


    always, period, without question. Thats just a tragedy waiting to happen.




    IBM technicians were screaming about the perils of of the need for data redundancy 20+ YEARS AGO


    that message got lost somewhere.

  • BOBBOBKK Level 1 Level 1

    Not on this thread for a bit, but for what it's worth, but with my 2013 iMac, I had loads of problems with USB3 connected hard drive enclosures - specifically, the Probox 4 drive and the Voyager - but tried Highpoint RocketStor 5212, using thunderbolt, and both Hitachi or WD hard drives are working perfectly. 


    I had also noticed my 2010 Macbook Pro had no trouble with the other enclosures, but of course was limited to USB2.  For me, Maverick's and USB3 was the problem combo.

  • southarena Level 1 Level 1

    Did the new Maverick Update 10.9.2 fix the disk utilities problem ? Did someone give a try ? Cheers

    Well I am fed up with WD, Seagate and Apple and they all can go to **** as far as I am concerned.

    So far this year I have purchased over a dozen new drives for differnet jobs and none have been Seagate or WD and I have instructed my guys to choose other alternatives when buying new devices. I am also giving strong consideration to doing the same with Apple, I have 2 systems due for upgrade this year and after being a loyal apple customer this whole experience has left me sour and likely to look at moving back to Windows and HP hardware.


    WD took over a month to respond and they as good as admitted liability and offered to cover the costs of data recovery till they found out the drive I needed recovering was a seagate product and then refused, even after admitting liability, they were happy to recover wd products, but nothing I lost on any of those drives was of any consequence.


    Segate took about 3 months to respond, and all I got was a form letter telling me who they recommend for Data recovery and the costs.


    Apple are yet to respond. When I phoned, the tech offered to help me wind back from maverick to Mountain lion, but was unable to assist on the HDD issues.


    While in the grand scheme of things i guess i am only a small consumer, spending $5-7k per annum on equipment, but it is $5-7K less ********** will see.


    I would be keen if anyone has any recommendations on suitable hardware, primarily running Adobe Creative Cloud applications for Video, Graphic Design and Web applicaitons, as well as Avid Media Composer 7, hence why I will look again at the HP products due to their specification preference.

    hard drives are $50 per Terabyte, on average.  


    Didnt you have multiple redundancies of your data, considering how extremely cheap hard drives are  





    Your Hardware Warranty

    Apple One (1) Year Limited Warranty - MAC
    For Apple Branded Products Only






    ...DATA and information are not covered under this warranty.






    All PC makers, Hard drive makers etc. have very similar disclaimers as above. 




    Never practice at any time for any reason the false premise and unreal sense of security in thinking your data is safe on any single external hard drive. This is never the case and has proven to be the single most common horrible tragedy of data loss that exists.


    Many 100s of millions of hours of lost work and data are lost each year due to this single common false security. This is an unnatural disaster that can avoid by making all data redundant and then redundant again. If you let a $60 additional redundant hard drive and 3 hours of copying stand between you and years of work, then you've made a fundamental mistake countless 1000s of people each year have come to regret.


    Many countless people think they're safe and doing well having a single external backup of their vital data they worked months, years, and sometimes decades on. Nothing could be further from the truth. Never let yourself be in situation of having a single external copy of your precious data.

    Must be just me that has a perfectly good WD My Book drive that has worked flawlessly from Lion thru to Mavericks. And a Seagate Aperture vault. And several other vaults dug out of old laptops and put in $2 enclosures. All fine.

    But then I didn't install any of their crapware.

  • Graeme Hodges Level 1 Level 1

    don't be sarcastic mate, yes media is cheap and we use **** loads of it. This particular working drive was my on shelf backup, I was in europe when first upgraded to maverick and phisically lost the working drive somewhere on my travels, that was bad enough, but getting home my intention was to update the media from there to get it off my macbook, but i ended up loosing my redundant copy as well. with the amount of projects I have either on HDD or LTO i feel I have an adequate archiving system it just ***** that work im progress that was on that drive is effectively lost.


    I am sure there are lots of you that have Seagate and WD products that are functioning just fine, but there are a **** load of us who have lost media and be it smart or stupid the contributing factor was defective software (that in hind sight should never have ended up on this machine, but it was so beit.) supplied and recommended by Western Digital and they have admitted that this was the cause, but will not take responsibility for the cost of recovery.


    I'm no IT Genius, but i'm not an idiot either, yes I love the mac products, but over the last few years thier customer service is getting worse and worse, yet we remain loyal, we are primarily running imac and macbooks, multiple ipads and iphones, We are already running Media Composer on HP Z800's at the office, and samsung are getting better with thier phones and tablets, im just saying, semi decent customer service on an issue that Apple contributed to would have kept a loyal customer loyal, instead im now open to all options.


    As for WD and Seagate, yes they own the market, but they aren't the only manufacturers out there and the 5 to 10 drives I go through a month are no longer theirs.


    Now im using my FTP more as a short term redundant back up when in the field, data is costing me a fortune, but I have learn some lessons... but at the crux of it, my systems were acceptable APPLE AND WD caused this and they are wiping their hands of it, its bull **** and not good enough.

    But none of that is Apple's fault, so I'm a bit puzzled by your comments about Apple's part in causing your problems. Apple doesn't tell anyone to install the WD software, nor can it control what software WD offers to its customers or recommends that they install.


    Also consider that the same thing could happen if you were using a Windows PC with an external WD drive. There is no guarantee that any third party software will work correctly with any OS. It is up to the software vendor to insure that it does, be it OS X, Windows, or whatever.

    That wasnt your redundant copy to which you speak......, but most people think that.


    1. All data on the computer is just that, your data

    2. All data on the 1st external HD is your backup

    3. Only the 2nd external HD is technically the first redundancy



    data redundancy begins at the 2nd external copy due to:

    1. it not being connected

    2. being the backup failsafe to the 1st external HD, not to the data on the computer which never counts in terms of data protection as "a copy".



    anything connected to anything is at risk and not by denotative definition a genuine redundancy


    Perfect portable redundancy is either:

    1. a second small HD

    2. uploading files via FTP to a private website or server.



    There are 4 conventional HD makers on earth, WD, Seagate, Hitachi, Toshiba



    They all can and do crash and fail, some statistically higher than others 






    Hard Drive Warning (all makes and models)

    Ironically but logical, new hard drives are far more fragile than one that has been working for several months or a couple years. So beware in your thinking that a new hard drive translates into “extremely reliable”!


    Hard drives suffer from high rates of what has been termed "infant mortality". Essentially this means new drives have their highest likelihood of failing in the first few months of usage. This is because of very minor manufacturing defects or HD platter balancing, or head and armature geometry being less than perfect; and this is not immediately obvious and can quickly manifest itself once the drive is put to work.

    Hard drives that survive the first few months of use without failing are likely to remain healthy for a number of years.


    Generally HD are highly prone to death or corruption for a few months, then work fine for a few years, then spike in mortality starting at 3-4 years and certainly should be considered end-of-life at 5-7+ years even if still working well. Drives written to once and stored away have the highest risk of data corruption due to not being read/written to on a regular basis. Rotate older working HD into low-risk use.

    The implication of this is that you should not trust a new hard drive completely (really never completely!) until it has been working perfectly for several months.

    Given the second law of thermodynamics, any and all current mfg. HD will, under perfect storage conditions tend themselves to depolarization and a point will be reached, even if the HD mechanism is perfect, that the ferromagnetic read/write surface of the platter inside the HD will entropy to the point of no viable return for data extraction. HD life varies, but barring mechanical failure, 3-8 years typically.


    Hard drive failure and handling


    The air cushion of air between the platter surface and the head is microscopic, as small as 3 nanometers, meaning bumps, jarring while in operation can cause head crash, scraping off magnetic particles causing internal havoc to the write surface and throwing particles thru the hard drive.


    Hard drives are fragile in general, regardless, ... in specific while running hard drives are extremely fragile.


    PDF: Bare hard drive handling generic instructions

    hard drive moving parts



    Some of the common reasons for hard drives to fail:

    Infant mortality (due to mfg. defect / build tolerances)

    Bad parking   (head impact)

    Sudden impact   (hard drive jarred during operation, heads can bounce)

    Electrical surge   (fries the controller board, possibly also causing heads to write the wrong data)

    Bearing / Motor failure   (spindle bearings or motors wear during any and all use, eventually leading to HD failure)

    Board failure   (controller board failure on bottom of HD)

    Bad Sectors   (magnetic areas of the platter may become faulty)

    General hard drive failure

    Have anyone find any solution?... I am in the middle of editing a video, and my HD GRaid has the same situation as you described ! SOLUTIONS PLEASE !

  • Richard Campbell2 Level 1 Level 1

    Hi fellow sufferers,


    I am now convinced that the answer to the Maverick vs. External Drive battle, at least for Western Dig drives, is to keep after WD and get them to send you a replacement drive in keeping with their warrantee.  My WD MyBook Studio was about a year old when I advanced up into Mavericks.  At that point the WD drive I owned began to screw up.  I disconnected it and dumped the WD software/smartware.  I got a replacement in the mail and sent the old one back.  The new MyBook didn't work either.  I disconnected it and again dumped all of the WD smartware, software and underwear and asked for another drive.  They sent me a third drive, a MyBookStudio, and I followed the installement directions.  And lo and works.  It remains mounted.  It backs up every hour on the hour and I don't notice that it is happening.  I even uploaded the latest correction to Mavericks so now I have 10.9.2 and the WD thing is still functioning like it is supposed to.  I am not sure what to conclude except that all of the WD drives that come off their assembly line are not exact replications of those before and after.  You gotta keep trying WD drives until you find the one that works with your computer.  I know that doesn't sound very technologically savvy, but I am not and the solution seems not to be either.  With this being stated, I rest my case.
