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)

    I'd also consider unloading disk arbitration & manually fscking via the Terminal. It may indicate if the issue is coming from Disk Utility or the disk frameworks. You know how to do this?

     

    Also see if Disk Utilities debug menu helps… Quit it & run

    defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

     

    Enable the all messages in the 'Debug > Debug Message level' & see what appears in the log.

    I’m not ignoring your suggestions. I just don’t know how to implement them

     

    The only fsck runs that I initiated are via Disk Utility e.g. once the Seagate 3T fails to mount. And I only did this to document Disk Utility’s inability to get the right answer when a drive is slow to mount because of the long fsck run initiated by the OS.

     

    I’m never sure when the OS will kick off a long fsck run. IOW I’m never sure why/when the OS will find the file system “dirty” during it’s initial fsck and then kick off a longer fsck run. The odds of this 'slow mount' used to be maybe 1 in 5 attempts, but since I placed this drive in Spotlight’s Privacy panel, several days ago, the odds have gotten much higher. For the last several days this drive has been mounting beautifully

    Mavericks main overhaul was spotlight.        That you have normal external HD mounts since you put it into the privacy panel away from the eyes of spotlight (as you mentioned a couple weeks ago) mirrors other threads about spotlight occurrences.

     

    Spotlight's overhaul (in the case of the WD-ware issues) had apparently created the perfect storm for the WD-ware and fsck, or the WD-ware alone (unlikely),  to 'repair' (corrupt) the external drive.

     

        In detailed examination that the main culprit here is the WD Drive Manager for most, since this can and does have the ability to re-initialized the drive and overwrite the partition table

     

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

    2. The question then revolves around the preceding events / actions taken by Spotlight / fsck (one or either) which forwarded the WD-ware to re-initialized the drive and overwrite the partition table

    3. The point of change for this to occur being Mavericks,    what then is the variable of change in (10.9), which impelled the re-initialization and partition overwriting.

     

    There its a necessary intermediary variable between the WD-ware (pre-existent on ML) and HD partitioning.

    That variable, reductively must be a fsck delay /command/ error  and/or Spotlight.

     

     

       Its a false premise that some have made in this thread that there is directed corruption going on (of course there IS corruption),     but as said, the commands to repair, are empirically identical to corrupt.

         Anything can be directed in error to ‘repair’ something when in fact the opposite is occurring.

     

     

    The release by WD to correct this was the:  WD Drive Manager v3.1.0 Release (11/25/2013)

    so what could we do now, sit and wait?

    is an updated wd driver expected to come from wd or apple?

    i see,

    and if someone does not want to install the smart ware and drive manager software? there is no need for myself to use these softwares...i would like to use the wd drives without any special wd software, i want to use them only with osx 10.9 default drivers.

     

    btw, i downloaded the latest drive manager 3 days ago by accident, it did not manage to show my 2 mypassport drives, so nothing changed in my opinion...

     

    thanks

    I've never had any external drive provided software installed. Amongst my drives are two WD drives which are still working fine under Mavericks. Unistall the WD software rubbish you just installed. Some are having issues, some are not.

    Yes, as stated on page 1 of this thread, if at all possible never use HD software...

    however you asked specifically about updated WD software.

     

    In the case of RAID (not used by you I presume),  HD software sometimes is necessitated and must be used;

    such software is for monitoring RAID sets / modes.

    What Plotinus said is Veritas: never install any Disk Software on a mac EXCEPT for Raid.

    You seem to be implying that the WD software should make previously damaged disks work again?

     

    I don't think that is ever going to be the case. Once a disk structure is damaged there is very little that can be done besides using recovery software or specialist services to retrieve files etc.

     

    Data recovery is a complex problem that should be tackled with the appropriate action & techniques depending on the situation & state of the disk. It seems to be something that is beyond what an updated disk driver / disk management software would do, this thread has several kinds of data loss/ errant disk behavior, how could WD account for these (assuming they were the cause)?

     

    Once a partition gets deleted or overwritten you have to take manual action to recover any data, otherwise you would simply be giving WD software the licence to change the disk structure with little or no human intervention. Giving them this type of access didn't work out well last time, do you trust them to recover the data too?

     

    As was mentioned a lot earlier in the thread, the disks have end user agreements that remove the manufacturer from responsibility for the data in situations like this. Haven't WD have offered a free license for disk recovery software? I think that the best you will get from WD.

     

    If you need the data from those damaged disks you will need to take action to recover it.

    no, my 2 mypassports 2GB are each empty drives, there is no data on it.

    i used it as a temp backup on my previous macbookpro with 10.8, where they were running fine.

    then i removed all data, sold my mbp, bought new macs with 10.9, and formated it with 10.9´s disk utility, 3 weeks ago. after that i could not mount it anymore. i thought it is corrupt, requested a new one, identical model, it came after 5 days, and there was the same problem, i could not mount it a single time.

     

    it is simply not showing up as HD in the finder and also not showing up in disk utility, left column, as partition/or as HD.

    i still dont think 10.9 corrupts harddrives, they are only not mountable..somehow

    i can put it anywhere else, and it mounts (10.8 it works, and i can use it with wd media player on my Plasma screen)

     

    thanks

    I have a 2T Seagate and I put it in a Century docking station. I have no WD software on my iMac with Mavericks. Sometimes, cannot mount the disk. I have to power the docking station off and then on againfor two or three times and then it mount. I also notice that sometimes the mounting time is quite long. I use FW800. I am now doing a long backup and I will use USB later and see if there is any difference.

    Yes FW800 is not working perfectly at the moment. If possible use USB. If the Seagate is USB3, use a USB3 cable (sounds silly but makes it work). I do not know the Century docking station, is it USB3 or USB2? This is important because it translates the sata to USB.
