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)

    PlotinusVeritas  The drive was already in the Spotlight Privacy.   Actually, removing the drive from the Spotlight Privacy fixed the problem. After removing it from the privacy tab and restarting the machine it meant that instead of taking 'about an hour' to copy 4GB of data, I could do it in a couple of minutes.  Thanks to info I've learned on this thread in regards the Mavericks Spotlight changes, I would never have figured that out.  Thanks all.

     

    Seems there are still a few bugs in Mavericks 10.9.1 (of course).  I should be able to have volumes and drives in the privacy tab of Spotlight preferences without it being a major issue correct?

     

    And aren't all these issues related?  Am I missing something but doesn't it seem like the problems with HDD indexing, mounting/unmounting and the like were possibly part of the problem that caused the WD software to behave the way it did and reformat the drives?

    1. This is the case of any operating system, Mac OS or otherwise.   3rd parties must make their products compliant.

     

    2. Apples Time Capsules are working fine, as well as the Hitachi hard drives inside same.

     

    There are 10s of 1000s of 3rd party hardware and software suppliers for Mac OSX,....all these companies know, without question their products are to be made compliant FOR Mac OSX,.... never the inverse is ever the case.

     

    3. Apple conventional hard drives currently only exist in:

    A: macbook pro non-retina (only 13" still made)

    B: mac mini

    C: Mac Pro

    D: Time Capsule

     

    A thru D work perfectly on Mavericks, as they should.

     

    You shouldnt worry about this in general, ...These boards are for those 'with problems' like an Emergency Room, everyone going along fine has no knowledge of this nor are coming here with any concerns.

     

     

    estApple, both before Mavericks, or even before Western Digital existed  -

    IBM technicians were warning users, very loudly, about the fragile nature of digital data on hard drives 20 years ago.

     

    Nothing has changed in 20 years regarding this nature of "necessitated data redundancy (multiple off-computer archives)".

     

    HD have gotten much smaller, and can contain more data, and are far far more reliable,... but the premise of same as warned by IBM technicians has not changed from those 20 years ago.

     

    Thankfully HD today are extremely cheap. 


    Peace

     

     

     

    And aren't all these issues related?

     

    Indeterminate

     

    working theory in test:

    B (WD-ware) causing A (fsck command) when on platform C (Mavericks), 

    or A causing B on platform C

     

    Known --    A fault B,   or B fault A   not occurring on platform D and E (ML and Lion)

     

    WD-ware (B) is forcing A to perform false command,... there is no logical likelihood that a false A is causing B to fault the HD, (open to correction)

    1. One or more aspects of WD-ware is/was (dependent upon version) Mavericks incompatible

    2. Once resident in Mavericks, the WD-ware can/is possible of cross-populating this fault to any HD,....WD, Seagate or otherwise

    3. Indications of fsck commands in conjunction with WD-ware ON Mavericks causing repartitioning / corruption.

    4. fsck commands in conjunction with WD-ware ON Lion & Mountain Lion had no such occurrence.

     

    ergo, B fault A-as-C-resident = current issue

    B fault A-as-D-or-E-resident  = not possible

     

    Resolution:    remove B on C-resident,

    Avoidance:    format all new HD,   never install B

     

    That the WD Drive Manager can: re-initialized the drive and overwrite the partition table

    (which is the premise of this thread)

    If external drives were not being wiped with ML and they are now with Mavericks, and nothing else has changed, then it's Mavericks that's doing it. Not the external drives.

     

    Duh....

    Tom, you still have time to edit such a ridiculous reply. Follow the thread instead of just jumping in to insult people. WD has admitted fault on their part with both drives and software.

    Mavericks cannot place "Mybook" on the partitioned HD (or 'corrupted' HD), this designation belongs to Western Digital and doesnt exist anywhere in Mavericks.

     

    What users report ON their HD after corruption (MyBook) doesnt exist in Mac OS, Mavericks or otherwise.

     

    You even wrote you have searched for "MyBook" and couldn't find it in Mavericks code.

    Could it be that it exists in a compressed or encrypted form?

    cox,

    no problems should happen when uninstalling WD software, problems will happen when you do not remove the software...

    In general, you should never install the extra softwares delivered with disks by a lot of suppliers: they conflicht with OSX, and cause not-spinning down at the minimum, and real data loss (WD in Mavericks) as the worst.

    After uninstall run an Etrecheck list and post here to see if something was left behind.

    @jeff

    I agree completely with Plotinus about better having 2x2TB instead of 1x4TB.

    callohanh,

    you not only have WD software still installed, but even worse you have the worst crap software installed that exists (pfff), Zeobit's Mackeeper.

    I also advise you to uninstall TechToolPro.

    cox:

    "Thanks, but LexSchellings wrote regarding Mountain Lion.

    The WD software had been designed for Mountain Lion."

    To be sure about this: you should never, in any OSX, install "supporting" software that comes with a HD from any supplier (except Raid situations).

    If you have something like this, you do not need to use supporting software even for RAID. there are buttons/switches at the front or at the back to configure the RAID types.

    Thanks. I really understand.  I should only use WD-ware for setting the RAID mode on my My Book Studio II (2 x 1TB as RAID 1) - then uninstall it immediately.

    I read that OS X sees this RAID 1 unit as one single drive - WD internal management does the parallel writing or mirroring.

     

    1.

    WD writes, when the RAID setting is changed (e.g. from RAID 0 to RAID 1) the disks are formatted as Mac OS Extended (Journaled). I read in this thread that this isn't good enough, and I should format again via Disk Utility. Is this really recommended for RAID units? What makes the difference? If I do it, will the WD internal management "forward" disk utility's formatting request to both 1TB disks?

     

    2.

    I don't need the "capacity gauge", but without WD RAID manager, how will I be notified if one of the disks gets defective?

     

    I know that normal external non-RAID drives can be controlled perfectly by OS X - but I don't fully understand how (and how far!) the communication works between OS X and RAID units/disks. I assume WD does some kind of "translation" in between.

     

    Many thanks.

    So I am running 10.8.5 on a iMac with 15 different WD drives and have never had a problem since 10.8.5 came out.

     

    Having watched the Mavericks issues with hard drives I have held off upgrading. I have run the WD Software Uninstaller 1.0.0.8 and yesterday ran EtreCheck.

     

    I found these items that seem to be related to western digital

    All of the Startup Items are in red

    Startup Items:

                      MissingSyncMounting: Path: /Library/StartupItems/MissingSyncMounting

                      PACESupport: Path: /Library/StartupItems/PACESupport

                      Parallels: Path: /Library/StartupItems/Parallels

                      ProTec6b: Path: /Library/StartupItems/ProTec6b

                      RetroRun: Path: /Library/StartupItems/RetroRun

                      WDBMService: Path: /Library/StartupItems/WDBMService <------this one here

     

    and

    Problem System Launch Daemons:

                      [failed]    com.apple.wdhelper.plist

     

    I am hoping for some clarification

    1. Am I correct in assuming that all of the Startup Items in red are not being used?  I think I read some place that Apple has moved away from using the Startup Items.

     

    2. What is 'com.apple.wdhelper.plist' related to.  My understanding again is this is Apple code and not western digital's code.  What problems does failure of the .plist to launch create?

     

    Thanks

    You see in StartupItems a lot of entries: delete them all, even Parallels should not be there.

    Go to your HD /System/Library/StartupItems/  delete them all.

    If you miss one in there, look in   your HD /Library/StartupItems/

    Do not touch the    com.apple.wdhelper.plist  : nothing to do with WD.

    Maybe it is better to post the complete etrecheck list here after this.
