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.

Mac recovery software  contain intelligently programmed techniques, that can locate your lost, formatted or inaccessible data in the disk drive and recover them successfully. Such utilities have been designed to shoot to the need and knowledge level of the common user, hence, don’t require any prior expertise on the same.

Stellar Phoenix Macintosh Data Recovery is a Mac data recovery application that can recover your data from any deleted, formatted or inaccessible HFS+, HFS Wrapper, HFS and FAT file system based volumes. The software is compatible with Mac OS X 10.6, 10.5, 10.4 and 10.3.9.

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.

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.

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.

Mac Entourage recovery programs offer self-descriptive graphical user interface to make the recover process quick and simple. They preserve absolute integrity of your valuable data with read-only conduct.

Stellar Phoenix Entourage Repair is the first and most advanced Entourage repair software ever made. It is designed to extract all Entourage database file items such as emails, tasks, notes, contacts, journals, and attachments for Microsoft Entourage 2008 and 2004. The software is compatible with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, and 10.4 Tiger.

Like other computer operating systems, such as Microsoft Windows, Linux, and UNIX, Mac OS X also contains a number of significant system files, libraries, and preferences. All these files, preferences, and libraries are extremely significant for properly functioning for your Mac OS X operating system based computer. However, under some circumstances, these critical files of your system gets damaged or corrupt and your system become totally unusable. This behavior of Mac OS X renders all your valuable data inaccessible and you come across severe data loss situations. In order to get your mission-critical data recovered, you have to opt for Mac recovery solutions, if there is no backup in place.

Mac OS X stores all your system related files, preferences, libraries, and the file that are required for appropriate working of your computer, are stored in ‘/System’ directory. The storage location of this directory may be different in every version of Mac OS X operating system. You should not make any changes to this directory, as improper editing of the files in this directory can cause severe problems.

In case /System directory of your Mac OS X system is either damaged or deleted by mistake, you may come across severe data loss problems. After corruption to this directory, operating system can not find require files, libraries, and preferences to boot up. Thus it refuses to boot up and can not let you access stored files from hard drive, causing severe data loss and creating needs of data recovery mac.

The /System directory may get damaged due to numerous reasons, such as:

You system is infected by viruses. They are malicious programs, which can remove or damage the /System folder or other critical data structures of your system.

Improper system shutdown. If your Macintosh computer shuts down unexpectedly due to power outage or system crash, significant directories may get damaged.

Operating system malfunction. /System directory is an important part of Mac OS X operating system and may get damaged due to operating system malfunction.

If any of the above situations occur, you need to format your hard drive and reinstall operating system, which eventually leads to critical data loss and put you in need of Mac data recovery.

Recovery is best possible using powerful and advanced third-party applications, known as Mac recovery software. They ensure quick, absolute, safe, and easy recovery in all cases of data loss.

Stellar Phoenix Macintosh Data Recovery is the most advanced and efficient utility to offer assured recovery of your valuable data in all data loss situations. The software recovers data from all HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes of Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

In Mac OS X operating system, sometimes the same disk space might be allocated to two different files. This is called extent allocation problem. Though, it is quite rare situations, but still it happens. In such cases, any one of the affected Mac files has to be deleted. If fsck or Disk Utility tool reports the problem on Mac hard drive, you should not install any third-party application.  This behavior removes your significant data file and cause critical data loss situations. In order to recover lost data in such cases, Mac recovery becomes need of hour.

How to fix Extent Allocation problem in Mac OS X using Disk Utility or fsck?

You can try solving the problem using Disk Utility in Mac OS X 10.4.2 or later. It can help you to overcome such problems without erasing entire volume. If your system or boot volume is not working properly, boot your system from Mac OS X 10.4.2 or later boot disk, and then run Disk Utility tool for repairing affected Mac volume.

You can repair only Mac OS X Extended (Journaled) or Mac OS X Extended volumes (also called HFS Plus, HFS Plus volumes, or HFS Plus Journaled).

If you are using the Disk Utility tool on Mac OS X 10.4.2 or later boot DVD or fsck for repairing affected volume, you can review some of the affected files with the help of ‘DamagedFiles’ directory.

Check for Files:

When you use fsck or Disk Utility in Mac OS X 10.4.2 or later versions to fix the overlapped extent allocation problems, the below processes take place:

Repair utility tries to move data of overlapped file to new location.

If move completes successfully, file is updated for using new location.

If move fails, the data is not moved.

In case you don’t have Mac OS X install disk or volume that you can use to boot your system, you should not install updates. It may cause further damage and cause severe data loss, putting you in need of data recovery Mac.

Recovery is best possible using advanced and powerful Mac recovery software. The applications do not modify original data on the hard drive as of their read-only and non-destructive conduct. The Mac data recovery applications are incorporated with rich graphical user interface to offer easy recovery.

Stellar Phoenix Macintosh Data Recovery software salvages lost, deleted, missing, inaccessible, and unusable files from Mac hard drive. It works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. The software retrieves data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.
