Recover the data

How do I recover the data after erase the Macintosh HD disk and also reinstall the system?
My laptop could not be turned on last Wednesday, but I needed to finish up my assignment and submit on Saturday.
I searched online a way to keep my data but the laptop could be fix up.
Under disk utility, I erased the Mac OS Extended (Journaled), then reinstalled the system.
It's said that in this way my data will be all kept, but when I finally got my laptop turned on.
All my data was gone including my files, applications, and so on.
I'm despairing for help right now. What can I do?
Thank you so much.

General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

  • I've broke my phone, it won't switch on, is there any way to recover the data from it?

    My phone has split up the side after I dropped it down some concrete stairs and now it won't switch on, so I need to know if there is anyway to recover the data from it, such as phone numbers, photo's etc. Anyone had this problem?
    I've tried plugging it in to the computer but it doesn't do anything, and tried plugging it in to the wall to see if that will switch it on, but nothing.
    Any help gratefully received! Steve

    If it will not turn on - you have zero chance of getting anything off the phone.

  • I accidentally deleted my trash. Is there any way to undo it/recover the data?

    Unfortunately, I don't have Time Machine set up on my MacBook Pro. And I can't do a "Cmd+z" because I've already performed other actions.
    I had probably 50-100 GB worth of .mov files. I don't have them backed up anywhere else. I have Lion, but I'm not sure if that will be of any help because I didn't have the files open in a program that would use the "versions" or "autosave" features.
    I already contacted Apple, and they said they couldn't legally recover the data because the trash has already been emptied, whatever that means.
    Is there anything I can do to recover these files?
    Also, are there any proven data recovery programs for Mac that will get the job done?
    Thanks!

    First, stop doing anything with the computer that had these files.
    Second, there are programs that can recover data.  How effective they are is based upon many factors that can't be listed here.  One of those factors is how much work you have done with the computer after deleting the files.
    I have had success with Data Rescue.  Past experience does not guarantee future results.
    You will need a second hard drive to save any recovered data.

    lost all my pictures and videos while updating ios7.1.1.
    i dont have backup to restore. how can i recover the data back?

    You should never update without making sure that you have saved everything on your computer first.
    You should import all pics and vids before attempting any update.
    If you have failed to save the data, then it is gone

  • External Drive failure.  How do I recover the data?

    Western Digital "My Passport" USB 3.0 External Drive failure message "the disk you inserted was not recordable by this computer".  I have Aperture masters, the Vault and other valuable data on this WD drive.  How do I recover the data?

    In these situations the usual choices are:
    (1) Recover data from your backup.
    (2) Recover data from a commercial service ($$$).

  • IMac just died on me. Need to recover the data.

    A friend of mine has a blue looking fruit iMac 600MHz, 256MB, and a CDRW, which just died and it made this 'click' noise when you press the power button.
    I'm guessing it is the power supply and it there a way to reset the power? I heard it is next to the RAM slot?
    Anyway, the most important is that I must recover the data off the hard drive, which I have successfully removed.
    Do I need some kind of Mac viewer in order to see the content in the hard drive under Windows XP?

    I don't know XP. Someone in this forum might know:

    How full is your hard drive? That may be affecting its ability to transfer data.
    And you can't transfer the entire home folder to a PC formatted drive. You can do the Movies, Music or Pictures folder, and your personal data files you created yourself, but not the Library folder. I would attempt to fix what is breaking your Mac rather than try to backup to a thumb drive, and better to recover to a Mac formatted external hard drive with Prosoft Data Rescue:
    http://www.prosofteng.com/
    And if that doesn't make for usable data with Media Four's MacDrive
    http://www.mediafour.com/products/macdrive6/
    Use Alsoft Disk Warrior 3.0.3 on the drive.
    If booted off Prosoft Data Rescue or Disk Warrior with nothing but an external hard drive, Apple mouse and keyboard you get a crash, that says your machine has a hardware problem. That will need to be fixed before you can recover any data.

  • HELP! old M505 has crashed and need to recover the data on it

    Hey all,
    I'm hoping someone out there has some creative idea on how I can recover the data that was lost on my old M505.  I went on a long vacation and when I returned it had completely run out of power.  Unfortunately after recharging it, the system started at the initial installation screens and had lost all of my addresses, which I had not backed up in a very long time.
    If anyone has any great ideas, it would be very much appreciated.
    Sincerely,
    Bob Last
    Post relates to: Palm m505

    Hi, and welcome to the Palm Support Community.
    Sorry, but there is no good news here.
    Your old m505 has what is called "volatile" memory, which means that it requires power to maintain it.  Once the batteries die, there is a small capacitor which holds just enough power to preserve data for another few days.  After that, it's << poof ! >> gone and there is no way to retrieve it if you don't have it backed up to your computer.

  • HT1212 Using the "if you have never synched with itunes" instructions, will I lose all data on the phone? That is the most important information, how to recover the data. The phone is fungible.

    Using the "if you have never synched with itunes" instructions, will I lose all data on the phone? That is the most important information, how to recover the data. The phone is fungible.

    Thanks @ KiltedTim, but losing "only" any data is really not acceptable and, in this case, the phone had not been backed up, but thanks for taking the time. Also, yes, fungible means what I think it means. An iphone is a completely substitutible commodity, unlike my data, so instructions that inform me as to how to fix a phone I could replace for a small sum of money while failing to address the more important issue of the data are almost useless - they potentially save me the $99 it would cost me to replace the phone if I were so inclined to trust another apple product. Not worth the hour it took to find them or the 35 minutes on the phone to confirm my suspicions about the data.

    There are some data I would like to recover from the HD so I'm trying to avoid reinstalling the system until I've recovered the files.
    Have tried to read from the HD using a cabinette and a new NP running Vista but it didn't work. Is there a general problem reading a XP HD from VISTA?
    Any suggestions how to recover the data would be very much appreciated!
    Johan

    cabinette ? Do you mean "USB Hard Disk Caddy" ?
    To recover your data, you can connect the HDD using a USB Adapter to another PC running XP or Vista. The drive should show up as a Drive letter (such as E: Drive), and you will be able to copy the files.
    When you say "but it didn't work", what was the problem exactly?

  • Accidentally deleted my Firefox data through the uninstallation of Firefox UX browser. Is it possible for me to recover the data?

    I chose to delete the Firefox UX's data when I uninstalled it and forgot that it shares the same profile and data with the current Firefox.
    How is it possible to recover my data, maybe with a files recovery software like Recuva or something?

    Hello,
    It may be possible.
    * Have you synced your profile data to any other machine using Firefox Sync? If so you may be able to sync it back by specifying 'replace this machine's data with the sync data' when you set up sync.
    * You may still have automatic backups of your bookmarks which can be restored. See here: [[Restore bookmarks from backup or move them to another computer]]
    * If none of this works then try Recuva. Point it at the folder where all the profile folders are stored. See here: [[Profiles - Where Firefox stores your bookmarks, passwords and other user data]]. If Recuva can recover the files in your old profile then you can use the Firefox profile manager to point Firefox at the recovered Profile. See here: [[Use the Profile Manager to create and remove Firefox profiles]]
    Good luck. I hope that helps.

  • IPhone backup is corrupted and not visible in ITunes. Can I recover the data on it?

    Hi,
    I am a Win 7 user. I recently upgraded my iphone 4 from ios 4 to ios 5. It seems that the upgrade process deletes all the data and then it recovers it from ITunes or ICloud backup. I did have only one backup and it was on ITunes. However, during the backup process I had some kind of error telling me that the backup is corrupted or something like that. Unfortunately I didnt pay enough attention to the error in order to quote it here. What happenned next is that the IPhone was stuck on the Conect to ITunes screen even thou it was already connected. Every time I was connecting the Iphone to ITunes, it was syncing, but it kept being stuck on that Connect to ITunes screen. To resolve this, I tried the Restore from a backup option by right clicking on the Iphone in ITunes. There I had only one choice of backup which was with no date. This solved the Connect to ITunes problem and the IPhone was up and running.
    The next problem was that once I configured the IPhone, I had no data on it - no pictures, no contacts, no anything apart programs I have downloaded previously from AppStore.
    A friend of mine assisted me, and showed me where the backups are stored on win 7 systems:
    C:\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync\Backup
    My understanding is that you have as many backups as folders in the Backup folder above. I don't see however one of the folders in the ITunes Restore from Backup list. It is the largest and oldest folder - nearly 2GB. All the rest is like 30-40mb. I believe that any chance I may have to restore any information from my IPhone is by restoring this backup and being able to upload it to the IPhone or read it somehow. My friend discovered that the .plist files are missing in this folder. In particular 4 files: info.plist, manifest.mbdb, manifest.plist and status.plist.
    We tried to cheat a bit by copying these files from one of the other backup folders. We also renamed some of the codes in one or two of the files, like the name of the folder, data and hour in info.plist. It didnt work. This folder remains unvisible by ITunes and therefore I cannot use it as backup.
    Your help is much appreciated for finding a solution on that one,
    Peppy

    If your backup is corrupted you cannot retrieve data from it.
    I've been working on a tool that repairs most iPhone (iPad, iPod Touch) backups that iTunes reports as corrupted -- it seems to be working fairly well for people we've had using it lately! If someone stumbles on this post and wants to try it out, the program is Decipher Backup Repair, and you can try it here:
    http://deciphertools.com/download-decipher-backup-repair.html
    As other people in the thread have mentioned, you can also try some third-party programs to read the backup and pull-out the important data so you at least have it in some capacity. We have one on the website I've linked above, in addition to the repair software.
    I hope this helps someone who finds this thread! Dealing with iTunes backups can be really painful, and I know it's horribly depressing to wait through a restore to get the corrupted message after SEVERAL minutes.
    (Note: As I mentioned, I work on the backup fixing software I linked to, so I stand to benefit, financially or otherwise, from the links I've provided.)
