    Four Days and who knows how many hours later , I am still in the process of trying to retireve my data.

    My advice is DO NOT download Mavericks until you have had your computer checked by Apple.

     

    Mavericks completely corrupted my Hard drive and have only been able to retrieve 90% of my data not to mention no applications. I am using a Mac Book Pro with Mountain Lion.

    Seems there are large number of people that have had issues with this update and yet Apple Support claim they have not had many customers with issues. I find that very hard to believe.

     

    As this computer contained my whole business to continue with work I bought a PC, and what do you know all those user friendly and what I thought were special features of MAC are actually now all available on PC.

    My love affair is well and truly over with Apple.

    I will no longer sing the praises or choose an Apple product first.

     

    I can't believe an upgrade to an operating system can be released by Apple without any warnings in regards to ensuring your system is ready for it. I have three colleagues who have all experience the same corruption of the hard drive and now must go through the long process of wiping the computer clean and starting again.

    Not good enough Apple, especially for those of us who are general users with no exceptional I.T. knowledge.

    Did you and your three colleagues have the WD software installed?

    Before the Mavericks upgrade, have you checked on the WD support page if that software is Mavericks compatible? *WD* assured it is!!! (That page has been removed.)

    Apple should have known about the danger and should have warned

    before the upgrade installation, but it's not their exclusive fault.

    I have a lacie 2big thunderbolt and after upgrading to mavericks after some day I cannot write to the disk anymore. I can read the files.

    Final Cut Pro X cannot recognize the disk and the files. Yesterday no problems, today this write problem.

    I have not installed raid but all as one large hard disk

    I've used these programs in the past on drives with various problems but no, I haven't run any data recovery on the Mavericks affected drive, which was a RAID array containing a total of about 7TB of data.  I haven't run it partly because I had most of the data backed up and am working on files restored from those back ups and partly because I have an open case with Apple tech support and they told me not to run any data recovery just yet as they are working on the premise that the data is there but hidden and there might be something they can do that will allow that hidden data to be revealed.  Although my faith in that solution is not high, I thought I may as well give them the opportunity to work on a possible solution.  However, it's been two weeks now and I'm beginning to get a bit impatient and tired of the 'wait, we're still working on it' replies...

    Thanks for the info.

    I believe the data will still be on disk (unless the OS spent hours overwriting it with 0's and 1's, which doesn't look like the issue here).

     

    The trouble is that HFS+ stores a lot of the metadata in a couple of folders, so if they cannot be repaired all you recover is the file data, which is what you mostly want, but not named 0001.jpg, 0002.jpg…

     

     

    I suspect that testdisk could get the partition table back (the boundaries of the volumes) and Disk Warrior may recover the catalog. It's unclear to me how the RAID was setup on these disks, so that complicates matters, but the data should hopefully be redundant on the disks depending on how it was setup.

     

    You can run multiple tools on damaged disks provided it isn't mechanially failing and you don't write to it. Clearly you need other disks to recover data onto. Disk arbitrator will stop the disk mounting automatically read/write.

    https://github.com/aburgh/Disk-Arbitrator.

     

    Hopefully Apple will get back to you & help you. I suspect the 10.9 licence agreement has a section about data loss that may mean they just point you towards Drive Savers or another data recovery company. Keep in contact with them and good luck.

    Does anyone know whether how the external drive was set up in the beginning make any difference.

     

    Specifically,

    1. If you just erase the disk and format at HFS+ (Mac OS Extended-Journaled)

    2. Partition the drive to a single or more partitions with partition types of GUID, Apple Partition, Master Boot Record using Mac OS Extended-Journaled?

    back it up. now.

    troutmouth Level 1 Level 1 (0 points)

    there are 2 codes - an activation and a licence - just make sure you're entering the right one at the right point.

     

    the software didn't help me - all the recovery software out there does the same thing for me - can see files but not directories or file names. so I'm stuffed.

    you don't happen to have a copy of that :"...not responsible for data loss"

    piece of paper do you PlotinusVeritas? particularly from WD?

    Though my legalese is poor, .....the part in blue basically means if you got $10,000 in lost data, WD is responsible only for the damages regarding the $100 (or so) hard drive.

     

    Though some lawyer may correct that conclusion.

     

     

    * However the part in pink (my highlights) indicate that WD would be liable if their HD jumps off the table and physically BITES you

    Apologies if you already know this, but files & directories are stored in the catalog.

    If you are lucky tools like Disk Warrior may be able to recover or repair the catalog. I think the volume header will need to be recovered to stand some kind of chance of recreating the volume. You may need to repair the volume with one tool & then try recovering the catalog via another.

     

    Spotlight adds lots of additional metadata, but that is stored in the /Spotlight-V100 folder in a custom DB format.

     

    Some tools will simply 'file carve' which looks for the file headers and tries to write that as a separate file.

    Carving out a working /Spotlight-V100 folder seems unlikey to me, especially considering how the recovered files will all be renamed & stored at new disk locations. Recreating the partition & recovering/ repairing the catalog seems like a much better option.

     

    Clearly it's insanely complex, but the HFS+ filesystem info is in Apple tech notes…

    https://developer.apple.com/legacy/library/technotes/tn/tn1150.html

     

    If you choose the right path you may get better results than file carving alone.

     

    I'm making an assumption that the damage was something that re-partitioned the disk. In which case critical parts of the catalog & original partition should still be on disk.

    UPDATE on the data recovery from corrupted WD MyBook II 4TB RAID (purchased Dec 2010) after Mavericks installed on MBP 15" (mid-2012).

     

    - installed Mavericks in October, no issues at all for several weeks but HD was acting erratic (slow to start, sleep-wake issues, etc.); HD only had videos, music and photos, nothing else

    - on Sunday, while disk was running, accidentally touched the power cord and power may have been lost to the drive (so improperly ejected); when reconnected, the MyBook and EFI icons (and seemingly "empty" drive) appeared

    - connected to non-Mavericks MacBook Air - still same problem, MyBook + EFI + 'empty' drive

    - panicked in disbelief

    - started scouring online to find out what may have happened, found this and other threads

    - downloaded Data Rescue 3, started the Deep Scan

    - after 20 minutes stopped Deep Scan and checked - files were appearing with filenames proper

    - restarted Deep Scan and ran for 24 hours to check entire 2TB drive

    - it seems like I have most of the files there, many with accurate filenames and metadata (mp3s) but many with not (lots of jpgs and mov files from iMovie)

    - I have another backup drive which has never been connected to the MBP with Mavericks which has 90% of the missing files, but that 10% (all jumbled jpgs and mov files which do play, but aren't in order, etc.) need organization which could take forever, or perhaps just left in a "Recovered Files" folder since they're really just photos and video

    - luckily I had my entire iTunes library loaded onto my iPod Classic 160GB (synced a few weeks ago) and items that were newer since then are all on my iPhone, so I will use Senuti to simply drag the entire lot onto a new backup HD as well as create a new iTunes library on the MBP

    - lesson: backup the backup, and forget RAID - just buy another drive and backup regularly, manually if can

    - what to do now:  probably recover all the corrupted HD files onto the new HD, backup the old HD, and leave on the Mavericks MBP only iTunes library (also backed up) and not use the external drives for now until some clarity on the situation

    I've been following this discussion with great interest, because my own WD Studio II    3TB x 2 was also hit by the Mavericks bug. I attempted data recovery with Data Rescue 3 and Kroll OnTrack EasyRecovery, and both yielded more-or-less the same results: a folder full of files with long numerical names and another folder with subfolders correctly named along with many files correctly named - yet none of the files with correct names can be opened. Every app I've tried says the files are damaged. Some of the numerically-named image files open - but there are thousands.

       Most of the content is a great big Time Machine backup, and I don't need it, but in a lapse of judgement I migrated folders of images there. Most were backed up elsewhere - but not all, So, to get those organized folders of images back, organized, I sent the drive in to Kroll. It's in the middle of analysis now, and I will report the results when they finish.

       In the meantime, understand that Kroll's in-house recovery service is not cheap; $65 to 'evaluate,' and $700 to $2000 for recovery. Ugh.

    I am very interested in the results of Kroll's analysis as I am considering sending mine to them.

    I used ontrack and data 3 recovery software and got different results from both , i will sort throrogh both for maximum retrieval  have given up on retrieving metadata.

    Both my thunderbolt drives and studio mybook drive are damaged as well . a An erase and reformat does not help and erasing free space does not work. WD are going to test the drives and try and find something . They still havenot got a grip on this
