HFS partition data recovery

Hello,
I damaged my partition table and now I need to recover the data of my external (backup) disk. I first tried repair the partition table with TestDisk but I had no success.
I now tried the demo version of Mac Data Recovery which can list the files http://www.diskdoctors.net/mac-data-recovery/software.html
Do you know of a free alternative of such a software ?
Thanks,
Tex

Most people use and recommend highly Data Rescue 3
http://www.prosoftengineering.com/
Yes, demo to know if it can see anything, maybe not the right tool for your type of problem.
And then there is iPartition - never used and have no knowledge of features.
Of course redundancy is best backup strategy, more than one, always one set that is off line, maybe more than one backup method, such as TimeMachine, SuperDuper, etc.
No free lunch (someone probably had to test, develop etc unless maybe hard drive vendor utility).
When it comes to drives that won't mount or work at all in OS, there are hardware sector copying tools that run around $450+ like DiscJockey.

Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive

Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
drive so all data gone included the drive which was encrypted by bit lockers.
For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first
http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
my data then i format the drive D and again tried to recover data using above software after decryption still no result.
Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanks

Hi ,
I am afraid that we cannot get the data back if the drive has been formatted even if use the
BitLocker Repair Tool.
You’d better contact your local data recovery center to try to get data back.

Data recovery from corrupt boot partition

The boot partition on my MacBook running 10.7.6 has a corrupt volume structure and will not mount, much less boot. The recovery partition boots but really doesn't let me do anything. Disk Utility can't repair nor even complete verification. I have lots of images which I need to recover, so am looking for a utility which might help.
Everything was apparently ok until the failure and the drive hardware checked out ok, so I'm hopeful my files are recoverable. A week or so ago I optimized the volume with TechTool Pro and the directory with DiskWarrior, and last night attempted to sync 1Password on my iPad with 1Password for Mac. This did no t work, probably because of my unfamiliarity with the procedure, but seemed to do no damage. When I ran TTPro last night from its eDrive partition it reported a volume structure problem on the partition which I started to fix with the program but then cancelled the analysis and decided to use disk utility instead. Disk utility also reported a problem but stopped the verification with the instruction to do a repair which it again could not complete. When I rebooted the system partition would again not boot but this time I got grey screen with a message that the debugger had loaded and <panic>. A message box said power down and restart, but that only repeats the process.
I'm thinking of attempting to install a system on an external boot drive and accessing the corrupt partition with a data recovery utility. Any insights, ideas or shared experiences appreciated. Thanks in advance for any desperately needed help.

The safest thing to do here is to install a new disk in the system and do a clean install of OS X. From there, you can put your corrupted volume in an external USB enclosure and mount the file system to try and recover as much data as you can.
It's likely obvious now, but it's REALLY worth investing in a large-capacity external storage or Time Capsure to use with Time Machine. Backups are essential. Hardware always eventually dies. We all need an effective strategy to deal with that.
A long time ago, I was backing my Linux system up to 4mm DAT. When the inevitable HDD crash came, I thought I was ready. Unfortunately, I hadn't tested recovery from tape and I ended up losing everything. Which is to say, until you know you can restore, you don't even have a backup. I lost thousands upon thousands of photos of my kids growing up.
BTW, if it is essential that you recover as much as possible, consider taking the disk to a data recovery service. Be warned: It's expensive.

Data recovery software that help recover lost partition due to using Disk Recovery Assistant on a 2TB HDD?

I Just use the Disk Recovery Assistant on my 2TB HDD and it wipe it clean. What are the best data recovery tool out there that allow me to recover the lost partition and see the file in folders view not files view like in some data recovery like Disk Drill?
using ML 10.8 something I tried appleXsoft but no luck.

My best suggestion is
Stellar Phoenix Mac Data Recovery
http://www.macintosh-data-recovery.com/
Download the free trial version of the software and use the option "Search Lost/Deleted Volumes", It will scan the drive and show you all lost partitions list on preview. Once you click on the selected partition it will show you again 3 options ,
Quick Recovery- This option is very effective on case of volume corruption
Advanced Recovery- This option recovers data from formatted volume and scans each and every block of volume for lost data.
Deleted File Recovery.- It scans unused blocks of volume to recover deleted data.
On successful recovery the software will show the files in folders view with the folder structure..In case you are unable to see the desired results you would need to go for Raw Recovery which will show results on file basis.This option is only required incase the previous option does not give you the desired results.
Cheers !!

How to create up-to-date Recovery Drive and Recovery Partition on Windows 8.1 U1.

I am running 8.1 and exploring the recovery options.
I'm periodically creating recovery images, etc. but would like to do better than that.
I'd like to know how to:
Create an updated Recovery Partition that will restore to a Recovery Image (WIM) that I choose.
Modify / Create a Recovery Drive that includes a system image
of my choice, as opposed to an image created by the manufacturer / supplier (and the extra work that that implies). If I can create an up to date partition and mark it as such, then I'm clearly done. Should I not be able to sensibly
make my own partition, how do I create this on a USB recovery drive? (The built in interface has a Boolean option, use hard drive recovery partition OR use nothing. This would be solved if it
also had an option to use current recovery image. I'm happy to write simple code to make this happen if that's what it takes.)
Put another way. I can make a recovery image at will, how do I create a recovery partition and recovery drive to match?
I'm no expert on the ins and outs of Windows 8.1 recovery, if this is already covered elsewhere, I'd appreciate a link.

I have documented an unsupported process for creating an automated recovery for use in a task sequence
here. However, if I read your post correctly you are suggesting being able to do this from USB media. The method for creating the recovery partition is simple. It is simply a partition containing a folder called RecoveryImage with your install.wim
inside. Reagentc is the tool that will actually tell Windows where that recovery is. While I don't personally have a use for what your suggesting, I may give it a shot just to see if it can be done. I suspect it will work.
Here are the links that got me started:

Unmerge hfs+ partition

hello.
I stupidly merged 2 hfs+ partitions using diskutil without reading all of the instructions.
I would now love to recover the data on the second partition. I'm currently trying to use data recovery tools to do this, but I'm not having much luck finding anything other than plists and pngs that I did not create.
Is it possible to unmerge the partitions?
Any help would be greatly appreciated and I would go out of my way to thank you.

I'm assuming the 'diskutil mergePartition' merely flagged the files as deleted, as the process took less than a second to complete, so, in both apps I'm using the 'deleted file recovery' function.
It did a bit more than flag the files as deleted. It destroyed the file system directory of the second partition & told the first partition's file system all the second's file space was available for new files. If you then continued to use the first partition, new files (like any downloads of the file recovery software you tried) may have been written to that now freed up file space.
That's why the first rule of data recovery is to quit using the drive with the lost files on it ASAP.
The file recovery software the hatter mentioned may still be able to recover many of the old files not yet overwritten with new ones, but it is very important that you stop using the drive immediately. That means not starting up from it & not mounting it for any other reason except as directed by the file recovery software.
You will need a second drive for the recovery process. It would have been far better to already have one & be using it for backups, which could have made all of this unnecessary, but now that you have learned the importance of backups, you can use the second drive for that once the recovery attempt has done all that it can.

Time Machine Recovery (after data recovery)

Several months ago, Disk2 and Disk3 in my 2007 MacPro 1,1 (OSX 10.7.5) became unreadable by the computer. To make matters worse, the Time Machine external backup became equally as unreadable. All at the same time! Drive 1, with the operating system, seems to be unaffected. The two unreadable drives showed up as "media" in disk utility, but didn't show up in Disk Warrior or any other similar programs (partition repairing) using the "terminal." I sent the Time Machine drive (WD Mybook Essential 3Tb) to DataRecovery.com and they found no phyical issues with the drive. There was, however,"Data Corruption in the file tables and data area" (according to the evaluation report). This was corrected and the TM drive was supposedly completely recovered.
Upon receiving the external drive (now replaced by a newer 3Tb Mybook), I replaced disk2 and disk3 with new 1TB drives (formatted with a single partition) and tried to perform a restore for these two drives. No such luck.....The drive was readable by the computer but would not actually enter into "Time Machine." I examined the actual drive and found an inordinate amount of Unix executable files, especially when going into the individual backups. The drive does show that they recovered 870Gb of information, but nothing seems to be readable much less recoverable.
I'm wondering if there is a workaround for any of this or whether I should contact the data recovery people to resolve this. I appreciate any help on this as it's become expensive and a bit deflating.......I still hold out some hope, though. Thanks. The drives were most likely corrupted by a generator that kicks on once a week (automatic maintenance) and temporarily cuts power long enough to turn the computer off...I've since gotten a UPS.

A general look at backup files......

Data recovery

First off I want to apologize because I am not computer literate so I will try to explaine my problem and hope someone can help me. The motherboard died on an older Compac with Vista 32 bit. I have tried to connect the hard drive as a second drive in
a newer Compac Windows 7 64 bit. I cannot get the system to give me access to this drive so I can transfer all my financial data off. I even tried to use the BlacX device to hook the drive up through the USB port. I can find the drive under Devices and printers
and it says it is working properly and I can also see it under Disk Management (Drivers are up to date) but it will not create a drive letter so I can access it. How can I recover the data from the old Compac drive??

Thank you for the articles. I am in practicality doing the opposite. I am trying to transfer data from a 2nd drive from an old computer to the primary drive on a newer computer. Am I to assume that I have a partition damage or missing if Disk Manager
shows the disk space as "Unallocated"? It is a 160 GB hard drive but it shows 149.05 GB Unallocated.
Hi,
Contact the professional in Data recovery service would be better if the data is very important.

Trying to get rid of error "The startup disk cannot be partitioned or restored to a single partition". Recovery HD visible.

Hello,
I've been stuck for some hours now trying different things to install Windows 7 on my Macbook Air, and I think now is the time to call for some custom help.
I'm using OS X 10.9.5 Mavericks.
So some months ago I just wanted to run Linux on my laptop so I installed rEFInd, shrunk the Macintosh HD partition by 25GB and booted on a linux live USB flash I burned using dd.
Then I used gparted to create my linux partitions.
It worked just fine, even though disk utility from OS X seemed quite unhappy about this (it seemed to have incorrect informations about the filesystem on these partitions, seeing them as journaled Mac OS while they were clearly not). At this point already, the Recovery HD from mac showed up in disk utility, which I found weird but didn't bother me.
But recently I needed windows on my Mac. So after a few tries for the triple boot, I managed to create a bootable USB stick with boot camp, which already showed me the message "The startup disk cannot be partitioned or restored to a single partition" and hence refused to partition/install himself.
So I thought "OK, that's no big issue, I can just partition with disk utility and then boot on the USB stick and everything will work fine". But when EFI booting on the USB flash drive I got stuck at the beginning of Windows installer with no keyboard or mouse support.
After some hours spent googling, I was unable to find a working fix for that, and as there was no support for my case (where I used bootcamp to create the bootable flash but NOT to partition/reboot) I decided to give bootcamp a try.
So I erased my linux partitions, and cleaned up everything I could on the HD with disk utility. That means I now have two partitions showing in disk utility : Macintosh HD and Recovery HD.
When using disk utility from terminal, the list is :
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                        EFI EFI                     209.7 MB   disk0s1
   2:                  Apple_HFS Macintosh HD            80.0 GB    disk0s2
   3:                  Apple_HFS Recovery HD             650.1 MB   disk0s3
But boot camp still isn't happy, and the message "The startup disk cannot be partitioned or restored to a single partition" keeps popping after the intro and I can't partition/boot from bootcamp.
So, as I don't understand what is wrong here anymore, any help would be greatly appreciated!
I will be watching the thread a lot because I really would like this resolved (or windows installed one way or another) this weekend; so any questions on my past manipulations or config just ask!
Thank you.

keyboard issues are also something of a common issue.
I wish the best threads were voted to the top of forums, something! Me, I literally burned out here, but after installing 10 Preview, wanted to "see what was going on" after hiatus of a couple years and see if anything had changed (no, not really!)
Also, these new Communities are not putting "more like this" and failing to help too.
I think rewriting Boot Camp Assistant's built in help and pdf would help a lot, and needs to be clearer and go into details. And Yosemite was not it seems tested against Boot Camp, and drivers for new Macs + new OS also lag behind. Again, common and no sign of improvement or change.
One of the tricks to the "can't partition" is rather simple - of course backup is step #1 and is spelled out - SHRINK the main HFS+ partition! then stretch it back to full length. Sometimes a reboot is needed, and sometimes even do a Safe Boot - not sure what but Recovry Mode might be a good option too. That does seem to consolidate free space, move files that are locked and cannot be moved otherwise, and allow BCA to partition, jusst be sure to have enough space left and large enough for a proper Windows install (and fudge factor).

[SOLVED] (U)EFI dualboot Win7 Arch Linux - partitions gone - recovery?

Hi everybody,
I have a slight problem with my (U)EFI dualboot system (Windows 7 and Arch Linux) which used to be configured using rEFInd like it is described in my previous post:
https://bbs.archlinux.org/viewtopic.php … 6#p1300356
<EFI PARTITION> is /dev/sda1 and I used to boot via <EFI PARTITION>\EFI\Boot\Bootx64.efi which then successfully either loaded Windows or Linux kernel.
Thanks to my own stupidity and a recent update of refind I decided to copy the new driver, font and icon folders to the <EFI PARTITION> in order to be up-to-date.
After doing so, the rEFInd boot menu had a third icon which said "Boot via \EFI\Boot\Bootx64.efi" and if I clicked on it a second rEFInd boot menu appeared with only the two icons for Windows 7 and Arch.
So I figured I could delete Bootx64.efi and ultimately did so, unfortunately. Afterwards I couldn't boot neither Windows nor Linux anymore.
Following this I went through my noumerous USB boot sticks in order to be able to recover the Bootx64.efi. Unfortunately the first USB stick was a Windows XP one which has the plop bootloader alongside:
http://www.plop.at/en/bootmanager/thebootmanager.html
Out of couriousity I entered this bootloader and found HDA and HDB (I assume resembling my SSD and my USB stick).
To my knowledge I didn't change anything but after entering the bootloader again I just found HDA left, HDB seemed to be gone. But I didn't think of anything bad happening yet.
Then I found a working Archiso which I booted and using blkid I couldn't find the partitions of my earlier system anymore, only its device and the USB stick:
/dev/sda: PTUUID="..." PTTYPE="gpt"
/dev/sdb1: UUID="..." LABEL="ARCH_201312" TYPE="..." and so on
/dev/sdb2: SEC_TYPE="msdos" and so on
Even within the EFI shell I could not detect any internal drive anymore (only fs0: which is the USB stick)
Using Archiso onboard tool testdisk I could find the old partitions. The correct result of the GPT from testdisk is:

Now the question is: Can I - using testdisk or any other tool - recover those partitions successfully so I will be able to boot again afterwards? I tested and I could mark them as:

Any help will be greately appreciated.

Issue resolved If you care to know how, read on:
Looking at the disk using gdisk was doing no good. Neither of the recovery options in gdisk did the trick.
I then returned to testdisk and restored the partitions (successfully). However, afterwards I was greeted by shell telling me the root device was not found (seems like UUIDs get changed when one restores them using testdisk). Adjusting the PARTUUID for root in <EFI SYSTEM PARTIITION>/boot/refind_linux.conf did the trick and I could boot up Archlinux again.
Windows 7 still didn't boot telling me the required device was inaccessible (probably wrong UUID, too). I could however not restore/edit Windows' BCD using bcdedit, see my post Status: 0xc0000225 boot selection failed; required device inaccessible:
To make a long story short: Removing bcd and running autorecovery from withing Windows RE successfully created a new bcd. Unfortunately, Windows writes its backup bootloader at <EFI SYSTEM PARTITION>/boot/EFI/Boot/bootx64.efi. This file originally was a copy of refind_x64.efi which I need to put at that location to be able to dualboot. After chrooting to my Arch system I could restore bootx64.efi, create a new fstab and everything is running fine now again.
Best regards and thanks for the help.

DATA RECOVERY for a hard drive that isn't recognized.

Hi,
I just found today that my hard drive is bad. I had one of those geek squad people come look at it and he was able to get it to boot from the Mac OS X Leopard CD, but my hard drive was no where to be seen.
I'm taking the hard drive to one of those places that specializes in data recovery. But, I was wondering...can they retrieve files that were on the desktop? Or are those files gone forever?

Hello Again! Now that there is serious soul searching going on now would be a good time to think about your backup plans for when you get everything up and running again. If the drive is going off to the recovery center worrying further won't help so I suggest coming up with a good recovery plan for times like these. Hard drives are going to fail and they always seem to fail at the most inopertune times but with a good backup plan this could have only been a restart. A second hard drive is a must if there is anything at all important on the computer. It can be an external or internal. I have 4 320 gig SATA drives in my G4 (and I really don't have anything very important on there) I usually keep two secondary bootable clones and rotate between them in case of a backup failure. Then I try to keep another clone on an external and finally I keep a partition with only a fresh install and my utilities for drive repair. I tinker a lot and I've screwed things up a few times but it really wasn't even a minor irritation. Good luck. Tom

Data recovery help and options

If you don't want to read the entire diatribe, please answer: Any suggestions as to which data recovery app is appropriate for a ThunderBolt Seagate GoFlex 1TB? It's been 21 hours, should I stop and restart First Aid?
I have a MBP15R that is about a month old. With it, I purchased a Seagate GoFlex 1TB drive with Thunderbolt adapter. I was away from the house for 24hrs, and had shut my MBP off prior to leaving. Upon return, I started the MBP and began my work. About an hour in, I realized I couldn't find a few recent files. I went to Finder, and realized the SGF wasn't mounted. It would not mount, and prompted me to run First aid. The log for this so far is:

It's now been 21 hours, and the boot support partitions for the volume as required has not completed.
I live-chatted with Seagate. The pertinant text is:
You: The question: with approximately 90% of the drive filled from backup, etc., how long should the process of 'updating boot support partitions for the volume as required' take? we're pushing 21hrs now.
Jason H: That is really hard to say. There is not a way to give a time on that, but I can tell you that it should not exceed 5 hours. At that point either the drive is unrepairable, or may be corrupted.
Jason H: It could be a bad drive.
You: ...hmm...your recommended course of action at this point? i'm an it director, am familiar with seatools, but unless i'm mistaken, you don't have a version of seatools for mac
Jason H: That is correct. The only thing we recommend on Mac is to use Mac First Aid Repair to try and correct any issues. I would still wait a little longer even though it has been some time. With the drive being 2TB and depending on the system, and what type of data, it could still be updating the partitions.
You: 1TB
You: video, audio, and documents/spreadsheets. the time machine backups took up over .5 the drive in just under a month. ok, so if another 24hrs doesn't resolve it, 3rd party tools to attempt a repair?
Jason H: The only other program that I can suggest, is even though Mac is not listed for Seatools, if you have an Intel based chipset on your Mac, Seatools for DOS can work. Otherwise, the only other thing I can suggest would be to search online for free recovery programs.
You: seagate will charge for data recovery even though the drive is 35 days old from purchase, correct?
Jason H: Correct, data recovery is not covered under warranty.
I'm getting a 2nd Goflex and USB adapter to push the data to once I get the drive operational, then exchanging the 'bad' drive and TB adapter.
Any suggestions as to which data recovery app is appropriate?

Sorry to hear your problem.
IMHO what you should of done was Shut down the Mac, Disconnected the drive from the Mac (Pull out the TB cord), Restarted the Mac and tried to Reconnect it once the Mac had started.
Could of simply been the drive was trying to draw to much power from the TB port, that is IF that drive did not have it own AC adapter, while the MBP was starting. But once it was up and running it may of been able to supply the correct power to the drive.
sorry I don't have any suggestions for Data recovery.

Which more beneficial data recovery services or data recovery softwares?

I am just try to figure out some thing which works best out of these two. As recently have gone through a recovery company Stellar Data Recovery http://www.stellarinfo.co.in/company/company.php . And after surveying i found companies proving software also.
The services paid more isnt it? but the recovery is maximum. what you think?

A perfect solution from the court of Recover data, is launched for the data recovery from damaged partition of windows operating system, it provides an edge to the failure of the data stored on the drive of windows, and deliver it safely to the users preferred
location on the drive. The software is enriched of user friendly attributes, that offers an outstanding services and support to the users. visit:- http://www.en.windowsrecovery.net and get more info

Data Recovery on External Drives

I have an external LaCie 200GB FireWire 400 drive, the F.A. Porsche one. While unmounting it before a trip I was in a hurry and unplugged the FireWire cable too soon and it came up with the customary message informing me as such. I paid it no mind as I was in a hurry and I'd done it once or twice before on accident and had suffered no wrath.
Anyway when I got home this evening I went to plug it in and found the drive unresponsive. I got a message saying I couldn't mount the volume but could initialise it in Disk Utility, so I did. The drive was showing but the volume with my data was gone, or rather it was showing up as "disk1s3" instead of "Rei" as it is named.
I tried the following steps to recover my data:
1. Disk Utility: I tried to repair the volume. I received an error saying it could not be done.
2. TechTool Pro: I did the drive test and it came back as having passed.
3. TechTool Pro: I tested the volume, found that the index was corrupted. Made sense.
4. DiskWarrior: I tried to recover it with DiskWarrior. During the recovering process the program became unresponsive and I got the beach ball of doom. After pressing AppleAltEsc I found the program was not responding and highlighted in red. I force-quit the application. I tried again and it proceeded to do the exact same thing. This time I noticed a message stating something along the lines of performance being slowed due to a drive malfunction. I was, once again, forced to force-quit the program.
5. DataRescue II: I attempted to use DataRescue II to see if I could at least view the files and transfer them off the drive and back them up to DVD so I could format the drive and reload all my data. Though it is visible to Disk Utility, DiskWarrior and TechTool Pro it is not, however, visible to DataRescue II.
6. TechTool Pro: I am now having TT P attempt to recover the data. I'm planning on letting it run into the night and hope in the morning it will be fine.
If anyone has any more recommendations on what I can do let me know. I can afford to buy another external to transfer all of my data onto that if I can access it long enough to pull it all off, but I need a program that can at least see the files to grab them.

Hi, Doug.
By not ejecting the drive before disconnecting it, the partition map was corrupted. Short of professional data recovery, you've covered everything and then some in my "Data Recovery" FAQ. If DR-II and TTP can't recover the data, then you're left with professional data recovery, per my FAQ.
I presume you don't have backups of the contents on the LaCie. After you recover from this incident, I suggest you implement a comprehensive Backup and Recovery solution addressing all of your drives. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ.
Good luck!
