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)

    Just took the drive that wouldn't mount in Mavericks, plugged it into the MBP with Mtn. Lion through FW. The drive wouldn't mount, so took it into Disk Utility, formatted, then verified. Disk working fine now.

    Not sure I understand what your issue was.

    Mine is that I had a working disk (MyBook Studio 2x1TB, factory default to a RAID0 2TB volume connected FW800, in the Spotlight scheme, formatted HFS Journaled with Disk Utility at the time I bought it a couple of years ago) that has been sort of wiped after the Mavericks upgrade and is now properly mounting OK in Mavericks Finder but with a volume name called "MyBook". In Finder drive is seen empty.

     

    Was your problem identical? Erase the Disk or Erase the Volume?

     

    I tried to plug the dodgy disk into a Mtn. Lion MBP, but unfortunately I've got the same result: Disk is mounting OK (still with "MyBook" as the volume name) but still no files listed in Finder.

    Not identical. Fresh G-Tech drive. Mounted fine, while reformatting the disk, the write became corrupted. Wouldn't mount, wouldn't repair. Disk or Volume. All OSX Journaled.

     

    Mounted on MBP with Mtn. Lion. Repaired disk and mounted fine. Could be the drive. Could be Mavericks. Not sure at this point. On a commercial set, so pulled the drive completely and haven't returned to check it further. Just wanting to let folks know, as well as Apple, that I experienced similar external drive corruption through USB 3 with Mavericks.

    Please can someone help me understand if I should be concerned:

     

    I have 2 WD External Drives, a My Book and a Mybook Live NAS that i use for Time Machine

     

    Since updating to Mavericks, back ups appear to be fine to my untrained eye, it seems to back up without issue, it works quickly and i can browse through whats in TM without issue

     

    My My Book LIve NAS takes forever to do anything and Im not sure why - could it be becuase its corrupted?

    I have been running Mavericks since the day of release.  Today, my WD MyBook was wiped clean of over 2 TB of data, including unreplacable photos and music.  Just prior to this event my computer went through a weird hiccup that required a couple of reboots and showed an error. I was running iTunes and all of a sudden it stalled playing a song after playing music all day.  There was an error that included "Unable to find driver for this platform: \"ACPI\"n"@SourceCache/xnu/xnu-2422.1.72.lokit/Kernel/IOPlatformExpert.cpp:1541 ...............

     

    Once it started up again, I was worried about the 27" iMac hard drive (2.8 GHz Intel Core i7, 14 GB 1067 MHz DDR3 memory) so I ran disk utility and that is when I saw the name of my drive had reverted back to the default and all files were gone!!

      Today, my WD MyBook was wiped clean of over 2 TB of data

     

     

    Prior to the WD repartitioning and corruption, ...did you run the uninstaller for all WD software as recommended and released by WD roughly 10 days ago?

     

    ....or was the WD control software still in place at the time of corruption?

     

     

    You can run recovery software for data extraction off the corrupted drive, however there is ultimate certainly that metadata has been lost.

     

    Many such recovery platform applications are listed in this thread,

     

    ....also contact WD, since they are apparently giving out free APP registration keys to peoples for data recovery software to help those who have been affected

    I need to buy a portable, external hard drive for back up. From what I have read it seems, the problem is only occuring with WD? Correct? Anyone had any problems with Seagate?

    the problem is only occurring with WD? Correct?

     

     

    absolutely incorrect, ...Yes, many numbers of seagate and otherwise have had repartitioning data loss,... as to chain of causation, it is still indeterminate to be certain.

     

    Known high risk potentials reporting are -

    RAID

    partitioned drives

    2TB and higher drives

    use of WD control software as resident on the computer regardless of WD drives or otherwise

    ,..increasing statistical examination of spotlight / finder as causative.

     

    To be certain, the mechanical drive in and of itself (be it seagate, WD, toshiba or hitachi) is playing no causative role in the corruption, no would it sensibly.

     

    I have tried to induce failure on nearly 20 drives, both partitioned and fake TM backup redundant copies (without the use of WD software) and cannot replicate it, oddly, with use of Mavericks on a macbook Air and Mac Mini

    As with most on this forum, I have experiance data loss. In my case on a WD Studio Edition ll Raid 0, that ran fine with all information until I restarted the new IMac. Shortly after I noticed the the Drive Name as My Book and found all data apparently missing. I have put that drive away until I hear something definitive as to whether anything will be able to be recovered in usable form.

     

    Pertaining lifesaver 101 question. This whole thing happed as I was transitioning from an old Mac Pro to a new iMac. When I upgraded to Mavericks the problem begain. I have an external WD Thunderbolt Duo 8T operating in Raid 1 (4T), which was copied from an internal Raid 1 in my MacPro. I have had no issue with the Thunderbolt drive and therefore have that data, as well as the original data still residing in my MacPro, which I will not get rid of until all of this has settled.....and may keep the drives anyway.

     

    As an experiment and after uninstalling all WD software using recent uninstaller on both my new iMac AND the MacPro running 10,7.5, I bought a WD Studio 4T drive and reformatted on the MacPro using Disc Utilities. Then cloned the drive using CCC over USB2. I just connected the drive to the iMac, still running Mavericks, and the drive mounted just fine with no problem - could see all data. I then restarted the iMac, with new drive still attached via USB 3 and all was fine with no reformatting issues. I have only done this once, but so far so good. Ultimately, as many have said, it's not a WD problem alone, it some unknow combination of external drives and Mavericks. I may leave this drive attached for a few days to see if if it fails eventually, as I have rududant backups.

     

    Whatever you do, make sure you have multiple backups, especially untill this issue is resolved by Apple and HD vendors.

     

    Hope this helps.

    PlotinusVeritas,

     

    Thanks for pointing that out, Since, thanks giving is coming near, I thought I might buy a portable HDD on the cheap. Do you think a software patch from Apple/HDD vendors will fix this? Or should I wait and not buy a HDD at all?

    Same problem - upgraded to Mavericks a while back, and suddenly today my 2010-era WD MyBook II 4TB showed up with the "MyBook" and "EFI" only, and all data supposedly gone from the original RAID partitioning.   It only showed 2TB as usable and available in the various utilities.   (Why, since it is a 4TB capacity?)

     

    I am now running Data Rescue 3 (says it will take 36+ hours) and hoping to recover what was lost (music, photos and videos only, really - I used the external drive just to store media).    A test run of DR3 showed that a lot of my files had the original filenames and the music files seemed to have the data (album, year, etc.)  

     

    I am worried that either the program will freeze, the drive itself (continuously running) will overheat, the data will be incomplete, the filesnames will be generic (despite my test run), and so on.  

     

    Is it some case whereby the data is there but not being reported correctly?   I would assume somehow given that I have perfectly fine filenames under "Music", etc. and also a bunch of jpgs in the "Images" section.    It doesn't seem like (at first glance) the data has been erased or reformatted or something - but then again, that is only after 2% scan finished in the first test.

    This post consolidates info I’ve posted previously and adds new info that may help others in dealing with their Mavericks external drive issues..

     

    As I have reported previously, I was in the process of cleaning up 4 Seagate GoFlex / Backup Plus drives that had been used as external Time Machine drives on our iMac and MacBook Pro running Snow Leopard prior to the clean install of Mavericks. What I hadn’t reported is that I had never used the Seagate software that came with these drives. My practice when purchasing an external drive is to copy off any software (just in case I should ever want to use it) and then I use Disk Utility to partition the drive with a GUID partition map and Mac OS Extended (Journaled) volumes. In other words I treat external drives as raw drives in a nice case.

     

    In addition to these 4 Seagates, I had just purchased a new Seagate GoFlex 3T FW800 drive that I was using as work space during the cleanup phase and am now using as the Time Machine drive on the iMac. The clean up involves deleting or transferring the flotsam and jetsam that inevitably accumulates in the free space of a Time Machine partition and then archiving the Time Machine backup file structure using Disk Utility to create a compressed read only .dmg of the Time Machine partition. This makes the Time Machine backup portable and allows restoring files directly from the mounted .dmg. This cleanup process is very disk intensive and requires lots of mounting and un-mounting.

     

    About mid way through clean up Mavericks damaged 2 of the drives’ directories making them un-mountable in Mavericks. But they would still mount (and verify) in Snow Leopard (10.6.8) on my MBP and Tiger (10.4.11) on my PBG4. So continued using the MBP (running 10.6.8) or the PBG4 for most of the "removing or transferring the flotsam and jetsam”, spot checking the files after transfer.

     

    But now one of the 2 Seagate Backup Plus drives, that first showed signs of trouble after being unmounted when attached to my MBP running Mavericks (10.9), will no longer mount when attached to the same MBP running from the Snow Leopard (10.6.8) boot partition. Luckily it will still mount (and verify) when attached to my PowerBook G4 running Tiger (10.4.11). The Seagate GoFlex & Backup Plus drives vary from 1.5T to 4T and have inter-changable bases with either USB2 or Firewire 800 interfaces. So I’ve tried both interfaces on this problem drive and get  the same negative results in 10.6.8 and 10.9 on the MBP. And the same positive results with 10.4.11 on the PBG4.

     

    I’ve already cleaned up the flotsam and jetsam on this drive. So I’m down to the nubs — creating the .dmg archive. And I’m not sure that the 10.4.11 Disk Utility can do this correctly with a Time Machine partition. Any advice is welcome.

     

    In summary…Despite Mavericks being unable to mount/verify/repair 2 of the drives I have been able to retrieve all of the data on these drives (except one older Time Machine backup) by simply mounting the drives on Macs NOT running Mavericks. And the only Thing I see stopping me from archiving that Time Machine backup is that it is stuck in Tiger territory.

    PlotinusVeritas,

     

    What is your aim in these tests?

     

    Are you trying to witness the corruption at any measure (with a view to analyse damage & help recommend recovery steps) or are you trying to see if it is only stock installed 10.9 causing the issue?

     

    Have you tried any tests with the WD tools installed on 10.9?

    Is it just because you are only concerned with stock 10.9 issues or were you unable to get copies of the WD tools?

    ~*One drive cannot be corrupted by this current issue, ...and thats on a server farm.

     

    consider buying a private website as part of triple platform redundancy. (HD, optical, online).

     

    private websites average $100 a year with unlimited storage and bandwidth.  (godaddy.com. etc.)

     

     

    online data storage is very easy to setup and very handy for travel, propagating certain files to friends etc.

     

     

     

    To drew reece---- I have the WD software yes but Im trying recreate the corruption without same

    Didn't work for me.   I connected my MyBook II to a Mac running OS X 10.8 and the drive still showed up as "MyBook" and "EFI".     I'm running the Data Rescue 3 on that same non-Mavericks Mac to try to salvage the files.
