Mac recovery utility to recover your data when Disk Utility fails

There are many possible reasons for which your Mac OS X based computer can go weird leading to data loss or inaccessibility. Among them, file system corruption following any unsystematic shutdown, any software or hard ware malfunction or virus/ malware intrusion etc are the most common ones. Users have always fascinated about the advanced technology and available features for almost everything in the Mac OS X. Users used to expect that their Mac systems can never go wrong, however, under such unpreventable errors, one has to look for Mac data recovery to recover back the data from the troubled media.

Let us take a real life scenario, where you have encounter some file system errors and data inaccessibility thereof. After that you are trying to repair the same with the tool Disk Utility. Disk Utility will run and may give you the following error messages:

Following the error messages, Disk Utility stops working as it fails to repair the damage caused to the disk drive. Hence, your data in the drive remains inaccessible and you have to think for any alternative third party recovery utility such as Mac recovery software to recover your data safely and soon enough.

“Verifying volume “hard drive name”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid key length
The volume hard drive name needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair”

In such a situation, where Disk Utility has already failed to repair, you may have to format and make a fresh installation of the operating system. With formatting it is sure that all your data from the disk will be wiped out and if you do have a single drive and that drive has been affected, then it is a situation to be worried about. However, if you have taken backup of your data, you can restore them from there and can have a shy of relief thereof. Else, you are left with a single safe choice in the form of any trusted Mac recovery utility.

Volume Structure Corruption and Hard Drive Errors in Mac OS X

Hard Drive errors are very common in any computer operating system, including Mac OS X. The disk errors generally occur due to corruption of critical data structures, system files, and metadata structures of your Mac OS X hard drive. In such cases, the system may not boot and you will not be able to access your precious data from Mac OS X hard drive. This behavior causes severe data loss and requires Mac recovery to be resolved, if there is no backup in place.

Mac OS X operating system offers an inbuilt disk repair tool to handle such situations, known as Disk Utility. When you run the disk utility on an affected Macintosh disk, you may encounter the following error:

“Checking disk “Mac OS X”.
Checking “Mac OS Standard” volume structures.
Checking wrapper System file.
Checking “Mac OS Extended” volume structures.
Checking for locked volume name.
Checking extent B-Tree.
Checking extent file.
Checking catalog B-Tree.
Problem: Invalid B-Tree Header, 0, 0
Checking catalog file.
Problem: MountCheck found serious errors.
Checking catalog hierarchy.
Checking volume bit map.
Problem: Overlapped extent allocation, 4, 4430
Problem: Overlapped extent allocation, 4, 4430
Checking volume info.
Problem: Volume Header needs minor repair, 1, 0
Repairing the disk.
The volume “Mac OS X” was repaired successfully.
Volume “Mac OS X” had overlapping extents. Two or more files were accessing the same disk block. Aliases to the damaged files have been created in the folder “Mac OS X damaged Files”.”

The disk can not be accessed in such circumstances. To extract data from affected Mac OS X hard drive, you need to identify the root cause of this behavior and perform data recovery Mac by fixing it.

Cause

As stated in the above error message, the problem occurs due to various reasons, including overlapped extent allocation, volume header corruption, volume bitmap corruption, and mount check errors. Such problems may prevent the disk from being mounted.

Resolution

Try repairing the disk using Disk Utility tool. If it does not work, format the hard drive, reinstall operating system, and then restore data from an updated backup. Mac data recovery tools are particularly designed to carry out in-depth scan of entire Mac OS X hard drive and salvage all lost data from it. You need not to be a technical expert to use these tools as they are totally easy to use.

Mac Recovery Software to Handle Boot Camp Errors and Data Loss

The current versions of Mac OS X operating system lets you install Windows operating system on your Macintosh machine, by making it dual-boot. It is possible through a specially designed tool, called Book Camp. The configuration is pretty easy and safe for the Mac files. After completion of the installation, you can boot your computer either using Mac OS X or Microsoft Windows. however, sometimes, the Boot Camp process may fail halfway and make your system unusable. This behavior calls for hard drive formatting, which eventually causes data loss. In such situations, you need to opt for Mac hard drive recovery solutions to get your precious data back.

When the dual-boot confirmation fails, you may not be able to boot the system if you use Mac OS X operating system. At the time of failure, you may encounter error messages similar to the following:

“The Disk cannot be partitioned because some files cannot be moved.
Back up the disk and use Disk Utility to format it as a Single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.”

Similarly, if you try to remove the Boot Camp volume, the below error occurs:

“The startup Disk cannot be partitioned or restored to a single partition.
The startup disk must be formatted as a single Mac OS Extended (journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.”

Cause

You may encounter this problem if your Mac OS X hard drive is corrupt or inaccessible by the Boot Camp program. In case you try to remove the Boot Camp partition, the error occurs if Windows partition is set as active.

Resolution

Try using the below mentioned steps to carry out hard drive recovery and resolve this behavior:

·     Format the Mac  OS X hard drive and install both  the operating systems from scratch.

·     Reboot your system  using Disk Utility and then remove the  Windows partition.

·     Restore data from  the most recent and clean backup.

In case you  go for hard drive formatting and do  not have a clean backup, Mac data recovery software becomes need  of hour.

Mac hard drive recovery programs are  incorporated with highly-advanced scanning mechanisms  to thoroughly scan entire hard drive and  salvage all lost data from it. These  programs are capable of handling all data  loss situations.

Stellar Phoenix Macintosh Data  Recovery is the best  data recovery software that ensures perfect  recovery of lost Mac data. The software  is designed to retrieve data from HFS,  HFS+, HFSX, HFS Wrapper, and FAT file  system volumes. It is compatible with  Mac OS X 10.6 Snow Leopard, 10.5  Leopard, 10.4 Tiger, and 10.3.9 Panther.

Inserted Disk Can’t Be Read by Mac OS X Under TDM!Here is the Solution

Target Disk Mode or TDM is an unique boot mode in Macintosh based systems that enables the drives of the targeted computer to behave as a FireWire mass storage devices. When a Mac that supports TDM, starts, it does not load the operating system but can be attached to the FireWire port of any other host system for formatting, partitioning or successful transfer of files. However, this process fails when you try to mount the hard drive volume of a system with an Intel-based Mac OS and the volume becomes inaccessible. This data loss situation does not have a safe solution other than any efficient Mac Data Recovery software to recover back your inaccessible data.

In the above instance of data inaccessibility, the error message reads as:

“You have inserted a disk containing no volumes that Mac OS X can read”

Explanation:

When you encounter the above error on your Intel based Mac OS X computer, mounting of the hard drive volume gets halted and you come across the inaccessibility issue. However, in Mac OS X 10.3.9 or earlier, when you connect an Intel based Mac OS X and start it in TDM, the hard drive might gets mounter and work as expected. The error dialog box consists of three options: Initialize, Ignore and Eject and you should opt for Eject or Ignore in order to dismiss the error box.

Cause:

The drive that was started in TDM and could not be mounted, must have been formatted in a non Mac format, such as FAT32 or NTFS. The FAT32 or NTFS file format can not be read by Mac under Target Disk Mode.

Resolution:

In the above case, you need to format the Mac OS X hard drive in a Mac supported file format and use it as startup volume in order to connect it at a FireWire port. While under TDM, you need a Intel based Mac system as the host system to be connected to the target system and being formatted. In this arrangement, you can use Disk Utility to format and repartition the hard drive. However don’t use a PowerPC-based Mac to format the disk as the Disk Utility will successfully format the disk but you will not be able to start the Intel-based Mac from it.

Formatting will resolve the problem for sure, but all your valuable data will be lost. Hence, these kind of data loss conditions require Data Recovery Mac to be be applied for safe recovery. Mac Data Recovery software are powerful applications that can recover your data from any such instance with ease. More over, they don’t require any technical expertise to operate.

Stellar Phoenix Macintosh Data Recovery is one of the most popular tool that effectively recovers data from HFS, HFS+, HFSX, HFS Wrapper and FAT file system volumes. This software is compatible with Mac OS X 10.5, 10.4 and 10.3.9 and a worthy choice over most of it’s counterparts in the market.

How To Recover Lost Data After Formatting Mac Hard Drive?

Mac OS X hard drive is a reliable and non-volatile storage media to store your data permanently. The drive holds your valuable data, even after power failure, until you delete it. The drive comprises of numerous data structures to store, access, organize, and manipulate your valuable data. In such situations, the critical disk data structures may corrupt and you need to format the hard drive to replace them with new data structures. However, this process also removes all the data from hard drive and causes data loss. In such cases, you need to opt for Mac data recovery solutions to extract lost, missing, deleted, and inaccessible data from problem hard drive.

The Mac OS X hard drive formatting process restructures entire hard drive to store new data. It fixes a number of problems, such as bad sectors, resource conflicts, cross-linked files, serious virus infection that cannot be fixed using an anti-virus software, file system corruption, and catalog file damage. You can format your Mac OS X hard drive using Disk Utility. Go through the underwritten steps to format Mac hard drive:

·     Open hard drive and then Disk Utility program.

Verify Entourage Database Using Database Utility to Detect Corruption

Is your Microsoft Entourage application crashing at the time of startup? Are you unable to access your significant information from Entourage database? This behavior may occur due to various reasons, which include missing system files and Entourage database corruption. It eventually renders your business-critical emails, notes, tasks, journals, contacts, and appointments inaccessible, causing serious data loss situations. At this stage, backup is the only option to avoid the need of Mac Entourage recovery solutions.

When you run across strange behavior of Microsoft Entourage application or Entourage database, you must first confirm whether the database is corrupt, before trying any solution. If Microsoft Entourage detects any problem with the database, it automatically initializes Database Utility to make the repairs.

If you suspect that MS Entourage database is corrupt, you must check it before rebuilding. You can verify database file by using the below steps:

·     Exit all Microsoft Office applications for Mac. It includes Microsoft Entourage and the Office Reminders.

·     Open the ‘Disk Utility’ tool in Microsoft Office/Office folder by double-clicking the same.

·     Select the affected database Identity that you need to verify.

·     In Database Utility dialog box, choose the Verify database integrity option, and then click to the Continue button.

·     Follow the on-screen instructions in Database Utility dialog box to successfully verify Entourage database.

·     If the process completes without any error, start Entourage application and access your data.

·     In case you encounter an error during the process, which indicates Microsoft Entourage database file corruption, you need to rebuild the database.

The database rebuilding or Entourage repair process is much like the database verify process. The only difference is that you need to select ‘Rebuild database’ option in place of ‘Verify database integrity’.

The Database Utility scans the affected Identity of Entourage database and copies valid data from source database to new database. After rebuilding, the new Entourage database is replaced with the damaged one.

However, rebuilding can not actually repair the corrupt items of Entourage database and thus they remain inaccessible. In order to retrieve them, you need to repair and restore the database using Entourage recovery software.
