    Hi , I logged on externslchard drive is x 10.11 and went to disk ulity trying to fix boot camp. Went into partition setting but then it started formally tying the 9999gb of data on he Mac mini. So I unpulged Mac mini. Now the hard drive won't display / hangs start-up

    In disk uptight the hard drive displays but under instead of he1 it says something like dis2hd ...

    Please help
    No. Backups either.

    How get data loads of work docs photos off the hd

    Oh. Well. That's not very smart.

    I guess you could try these guys:

    Here's what I'd suggest:

    Sometimes DiskWarrior can repair a drive situation like this. Worth a try, but don't get your hopes up.

    1. Download DataRescue (free to download and use in demo mode).

    2. You will need a SECOND drive of sufficient capacity to serve as the "scratch and recovery" drive. You MUST buy or use a second drive. No way around this.

    3. Launch DataRescue and "aim it" at the problem drive. Does it see it (even if it isn't mounted on the desktop)? If so, try the deep scan mode and see if it can recover anything to the scratch drive.

    However, if the above doesn't work, you may need to go further:

    4. Re-initialize the problem drive. YES, you ARE reading that correctly. Just do a "quick erase" but do not -- REPEAT, DO NOT -- choose to "zero out" the data by choosing "secure" erase. YOU DO NOT WANT TO DO THIS.
    You only want a quick initialization so that the data "out on the sectors of the drive" will be left intact -- and RECOVERABLE.

    5. Now "aim" DataRescue at the re-initialized drive and tell it to do a "deep scan". THIS MAY TAKE SOME TIME.

    6. DataRescue will scavenge the sectors of the drive, and will re-assemble what it finds.

    7. DR will let you recover ONE (and ONLY one) file in demo mode.

    8. If this is successful, and if you can see a long list of potentially recoverable files, NOW it's time to pay the registration fee and get a code. Then you enter the code in DR and it does its thing, recovering the files and copying them to the scratch drive.

    9. Be aware that you are going to lose previous folder hierarchies and many if not all file names. But this "is the cost" of data recovery. Your consolation is that you get the -data- itself back.

    This worked for me on a "bad partition" that wouldn't mount no matter what else I tried.

    No promises that it will work for you.

    Be aware that professional data recovery on a 1tb drive is going to be VERY expensive. Probably over $1,000.

    I agree mostly with Fishrrman but I am not certain point 4 is beneficial because in this kind of situation it is important not to make any changes to the drive. Using Deep scan should be enough.

    Otherwise the post provides good instructions.

    OP: Hopefully you can restore data. However if the drive was mechanically damaged DataRescue is unlikely to restore much of the information and you will likely need professional help which will very expensive...

    Afterwards make a backup because you don't want to experience this kind of situation again!

    Have you booted the Mac from external drive?

    If not then you need to install OS X into external drive via Recovery mode (keep Command-R pressed during startup). Then select install OS X, accept license and select external drive when asked where to install OS X. Do not install OS X into the drive you are trying to recover data under any circumstances! Doing so will very likely overwrite data you are trying to recover!

    If you are booted from external drive then you can just drag Data Rescue software into its Application folder and open Data Rescue. Then follow Fishrrman instructions in post 3.

    DataRescue should go into the Applications folder on your INTERNAL hard drive.
    (this is because the drive with a problem is -external-)

    From there, you run it as you would any other app.

    You "aim it" at the problem external drive.

    You "set it up" to recover data to your SECOND "scratch drive".

    I would try something called "deep scan" (or similar) first.

    Be aware that if the drive won't mount in the finder, DR may not be able to "see it" either.

    This is why I suggested the process in post #3 above.
    If your disk directory is hopelessly damaged, it may still be possible to re-initialize the drive and recover the data, SO LONG AS YOU DO NOT ZERO THE DATA OUT by using the "security" option.

    A "quick re-initialization" doesn't touch the actual data "out on the platters".
    All it does is install a clean directory.

    Once you do this, the drive will mount in the finder, but it will "look like" there's nothing on it, because the drive's directory is "clean" and "not connected" to what's really out there on the sectors of the drive.

    DR can "look around" the "empty" directory, and "go right to the drive sectors".
    It can scavenge up the pieces of the old files, re-assemble them, and copy them to the scratch drive.

    This DOES work -- I've done it myself.

    It's a Mac mini. It just stays at Apple logo.

    Can I put in data rescue on an external drive via MacBook pro. Then I boot data rescue via option key
    --- Post Merged, Jan 11, 2016 ---
    But how can I put data rescue on the internal drive when I can't even reach the login screen

    You could 1. install Data Rescue into Macbook Pro, then 2. connect the drive which has the missing data and 3. another 1Gb external drive where Data Rescue will save the (hopefully) recovered data.

    Then follow the instructions provided earlier, it will likely take several hours to scan the 1Tb drive so be patient and don't interrupt the scan!

    Thank you but it's a Mac mini built in hard drive. What if I boot up external clean osx install via connected Mac mini and then select the drive

  12. Ebenezum macrumors 6502a

    That will work but there is easier way:

    If the Mini and Macbook Pro both have either Firewire or Thunderbolt then you can just connect them with Thunderbolt or Firewire cable, start the Mini while pressing T on the keyboard connected to Mini. It will show on the Macbook Pro as a external drive. Then connect external drive to Macbook Pro and follow previous instructions.

    In the future if you need to ask help for another issue its better to provide exact model/s, hard drive etc. and all other relevant information in the first post, it would have made this a lot easier to explain...
