Mac OS X Extended Recovery after Hard Drive Formatting

madisonwalker — Tue, 13 Jul 2010 05:14:52 -0800

Mac OS Extended or HFS+ is a journaled file system, invented by Apple Inc. HFS+ is the successor of HFS (Hierarchical File System). It is an advanced and stable file system and offers you excellent performance in storing, retrieving, organizing, and manipulating the data. Along with all advanced security and performance features, the file system supports journaling feature to prevent file system corruption in case of improper system shutdown and prevents need of Mac data recovery solutions.

Journaling is a file system feature, which helps protect file system against improper system shutdown, system crash, power outages, and hardware failure, minimizing the need for file system repairs. It improves the computer's availability and the fault resiliences that is particularly noteworthy for the servers. The journaling feature protects integrity and consistency of HFS+ file system.

Although, HFS+ is a reliable file system, in some cases it faces several integrity and consistency issues that may corrupt it. In case of severe file system corruption situations, you need to replace the corrupt file system with a new one.

It is possible to replace the file system only by formatting the hard drive and reinstalling operating system. Formatting is the process of removing all the data, applications, data structures, file system, and operating system from Mac OS X hard drive and then reinstalling them.

Though, this process helps resolve most of the file system related problems, it also causes critical data loss. All your precious data is removed from the disk after formatting. You may run across grave situations after hard drive formatting, if there is no clean and current backup in place.

Most of the Mac OS X users think that the data is deleted forever after hard drive formatting. But, this is not the case.Data recovery Mac is still possible. When you format a HFS+ file system based hard drive, only the system data structures are removed. These data structures are used by the operating system to locate the files. When these data structures are removed, the stored files can not be located or accessed.

You can easily recover your valuable data from HFS+ file system volumes after formatting using Mac disk recovery software. They help you to methodically scan entire Mac OS X hard drive and extract all lost data from it. The Mac recovery programs offer safe recovery.

Stellar Phoenix Macintosh Data Recovery is an excellent solution for handling all data loss situations, including hard drive formatting. The software supports recovery from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. is the software can be used with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

How to Wipe Files from Mac Hard Drive?

madisonwalker — Mon, 12 Jul 2010 02:21:06 -0800

Are you willing to sale or donate your Macintosh computer? If yes, then you should think for a while. Have you completely erased or wiped your significant data from the hard drive? It is pretty important to completely remove the data from disk before you give it to anyone else. Simple deletion of files or hard drive formatting is not a safe way. The file can be recovered after such kind of deletions and can be misused by malicious users. To ensure safe removal of your data, file eraser Mac is required.

Deleting Does Not Actually Delete Files

Mac OS X operating system uses file system for storing, accessing, organizing, and manipulating files on the hard drive. Every file or directory, stored on Macintosh hard drive, has a unique entry in the file system. This entry is referenced by the operating system to locate and access files/directories from the hard drive.

When you delete a file, only the reference of file is deleted. The file remains intact on the drive. However, Mac OS X operating system can not locate and access files because the file's reference that is used by operating system is missing. In such cases, it seems that the file is gone forever. In fact the file is recoverable in such cases using Mac data recovery software.

The same thing is with hard drive formatting also. Formatting removes entire file system from the hard drive and make it as a RAW. However, recovery is also possible from a RAW Mac OS X hard drive. So, your confidential files are still at the stake of misuse.

Physically destroying a hard drive is a way to tackle such cases, but it is not environment friendly. Other than that, you need to purchase a new hard drive for your system.

The perfect file wipe Mac is to overwrite the deleted files, which is not possible manually. For this purpose, Mac OS X operating system provides an inbuilt utility to erase a hard drive volume, called Disk Utility. But, this tool also has a drawback that it can not wipe selected files from a Mac hard drive volume.

In such critical situations,Mac disk wipe software come for your help. The applications are designed to overwrite the selected files by random binary digits- 0 and 1. These Mac wipe tools are capable of completely wiping all the selected files in a quick and easy way.

Stellar Wipe Mac is an advanced file eraser utility that wipes selected Mac files and folder beyond recover capabilities. It is usable with 10.6 Snow Leopard, 10.5 Leopard, and 10.4 Tiger. The software enables you to select a wipe algorithm on your own.

Verify Entourage Database Using Database Utility to Detect Corruption

madisonwalker — Fri, 09 Jul 2010 02:13:36 -0800

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 recovery 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.

In Mac OS X 10.5 Leopard, the Disk Utility tool is able to resize your hard drive partitions or repartition a hard drive without erasing stored data. Mac released a new version of Mac OS X operating system, namely Mac OS X 10.6 Snow Leopard. You can upgrade to it from your Leopard system. However, some beta software does not work in Snow Leopard. Thus, disk repartitioning may be required to create a new partition and install Snow Leopard on it. For perfect functioning of your system after disk repartitioning, the process of disk repartitioning should complete successfully. In case, the process is terminated due to any reason, like low disk space and system crash, you may not be able to access existing partitions and data. This behavior leads to significant data loss and calls for Mac data recovery.

Backup Your Data Before You Proceed for Disk Repartitioning

You are highly recommended that you should not mess up with actual partitioning structure on your Mac OS X hard drive without creating a valid backup of your valuable data first. The partitioning process may go wrong in some situations and problems may take place, calling for data recovery Mac to be fixed.

It is quite possible to lose access of your business critical data in case of disk repartitioning process failure. So before performing the disk partitioning operation on your Mac OS X hard drive, you should make sure that your backup is valid and updated. If you repartition the hard drive without an absolute backup, it can be very risky.

How to Repartition a Mac Hard Drive?

To repartition a hard drive using Disk Utilities, follow the underwritten steps:

Launch Disk Utility.

Select the hard drive to repartition, in the list it shows.

Drag corner of partition box for resizing it.

Click '+' button to add new volume.

It prompts for confirmation. Confirm it.

This way, you can easily repartition of your Mac hard drive. But, what if you do not have a backup and the process fails? It causes serious data loss and Mac recovery becomes need of hour.

Recovery is possible using powerful and advanced third-party applications, known as Mac Disk recovery software. They are powerful enough to perfectly and safely recovery all lost data from Mac OS X hard drive.

Stellar Phoenix Macintosh Data Recovery is the most efficient and useful utility in all data loss situations. The software recovers data from HFS, HFS+, HFSX, HFS Wrapper , and FAT file system volumes. It is designed for Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

Mac OS X operating system enables you to divide your hard drive into several volumes, for efficient management of your critical data. A system must contain at least one startup volume. The other volumes can be non-startup volumes containing your data. Startup volume contains operating system, which is used to boot your system. Non-startup volumes are very important for the user from data point of view. In case something goes wrong with non-startup volumes, also called unmountable volume, all your data become inaccessible. This behavior leads to significant data loss and Mac data recovery becomes need of hour, if backup is not available.

When your Mac OS X hard drive gets logically damaged or it comes across any sort of errors, you can try resolving them using Disk Utility. It is an inbuilt utility of Mac OS X operating system, which checks integrity and consistency of damaged hard drive. It also fixes minor file system errors. However, this utility sometimes fails to work on non-startup or unmountable Mac OS X hard drive volumes.

When you try to verify or repair a non-startup and unmountable Mac OS X hard drive volume using Disk Utility application, the repair process appears to start, but then it is aborted. At the same time, you may come across the below error message:

“Repairing disk failed with error. Could not unmount disk.”

After the above error message, when you check the Console of Disk Utility, you see the below entries:

“Verify and Repair disk “Storage”
The disk “Storage” could not be unmounted
Could not unmount disk for verification
Repairing disk failed with error. Could not unmount disk”

In some situations, your Mac machine may not respond for a few minutes after this behavior.

If you are unable to determine which files or directories are open on your hard drive that you need to repair or verify, reboot your system and then mount your hard drive again.

To fix data loss from the damaged unmountable volume, go for data recovery Mac solutions. Mac recovery is best possible using advanced and powerful third-party applications.

The Mac recovery software use efficient scanning methods to successfully recover lost data from damaged hard drive. They are incorporated with interactive graphical user interface to provide easy recovery.

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

Disk Utility Live Verification Fails on Unmountable Mac OS X Volumes

madisonwalker — Tue, 18 May 2010 23:32:07 -0800

Hard drive inconsistency and integrity problems are very common in Mac OS X operating system. To handle such problems up to an extent, Mac OS X operating system provides you an inbuilt tool, called Disk Utility. It verifies your hard drive and repairs the damages in some situations. The utility can be run from boot disk of Mac OS X operating system. You can run this program even on the live hard drive. This process is known as Live Verification. However, in some situations, Live Verification of Mac hard drive may cause serious problems that lead to hard drive failure and data loss. At this point of time, you need to go for Mac recovery solutions, if there is no valid backup in place.

You should keep the below things in mind while performing a Live Verification of Mac OS X had drive:

The Live Verification works only on Journaled volumes of HFS+ file system. If you try it on non-journaled volumes, you may get an error message stating: “ERROR: could not freeze volume (Operation not supported).”

The progress indicator of Disk Utility might stop advancing, applications may become unresponsive or work slow, or your system may freeze during Live Verification.

Once you initialize the Live Verification process, you may not abort it.

You may come across some problem when you attempt to repair or verify a unmountable Mac volume.

What happens when you run Live Verification on unmountable Mac volume?

Disk Utility program may freeze without showing any error, or stall the machine for few minutes, while repairing or verifying the unmountable volume.

When you attempt to verify a non-startup volume and Disk Utility cannot unmount it for any reason, verification process may start, but and may stop without any error.

After this behavior of Disk Utility and your Mac OS X system, the drive remains in inconsistent and damaged state. You cannot access data from such drive and need to perform Disk Recovery Mac by resolving this issue.

You can easily recover your valuable data using Mac recovery software as they have interactive graphical user interface. The Mac data recovery applications employ high-end scanning techniques to thoroughly scan entire hard drive and extract all lost data from it.

Stellar Phoenix Macintosh Data Recovery is the most efficient and comprehensive utility that ensures absolute recovery in all data loss scenarios. The software safely recovers lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. It is usable with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.

How to Fix Cache, Permission, Directory, and Disk Corruption in Mac OS X?

madisonwalker — Tue, 18 May 2010 04:35:27 -0800

Mac OS X operating system is made up of a number of resources, which work together to make your system bootable and functional. These data structures may be different as per the version of operating system. The most common resources of the Macintosh operating system are cache files, preferences, and system directories. When any of these data structures gets damaged, your system can not boot and you can not get into your system to access stored data from its hard drive. This behavior leads to serious data loss situations and requires Mac Data Recovery to be fixed, if you do not have absolute backup in place.

You may come across a number of problems in Mac OS X system, if any one or all of the below three areas of your Mac machine are corrupted:

The directory of Macintosh start disk.

Permissions on the system files and directories.

User-specific, Application, or system cache files.

This behavior may occur due to any of the below reasons:

Application or system crash.

Hard reboot: rebooting your system after freeze or hand through power button.

Power surges.

Failing or defective hard drive.

Application installers that reset system permissions improperly.

Data loss risks:

Directory corruption, hard drive failure, or system crashes are critical problems that can lead to serious data loss. If your data is important for you, you should maintain an absolute backup of all your significant data. It minimizes possibility of data loss and need Mac Disk Recovery solutions.

While Disk Utility can generally fix directory corruption, it can not handle file corruption. Some kinds of directory damages, like overlapped extents or files, can cause file corruption and data loss.

Resolution:

You can try resolving this problem using any of the below steps:

Reboot your system.

Check hard drive errors using Disk Utility or fsck tool.

Reset system permissions.

Perform cache cleaning.

In none of the above methods works, you are recommended to perform Erase and Install operation of Mac OS X operating system. However, it removes all the data from hard drive and needs Data Recovery Mac to be fixed.

You can easily retrieve your lost Mac data using Mac Recovery Software. The applications are particularly designed to methodically scan entire hard drive and extract all lost data from it. With read-only conduct and graphical user interface, it is quite safe and easy to use.

Stellar Phoenix Macintosh Data Recovery software is powerful enough to effectively scan Mac hard drive using advanced scanning techniques and recover all lost data. The software supports recovery 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.

Damaged System and Data Files Cause Data Loss in Mac OS X

madisonwalker — Tue, 11 May 2010 04:31:03 -0800

Sometimes critical problems affect significant files, without any prior warning. In such cases, your system and data becomes inaccessible inexplicably. It may also render the entire storage device useless. File corruption may occur due to numerous reasons, such as virus attack, file system corruption, improper system shutdown, incomplete operating system upgrade, and more. Corruption of either system file or data file, eventually leads to serious data loss. At this point of time, an absolute and updated backup comes to your rescue. However, if backup is either not updated or not available, you need to go for Mac Data Recovery solutions to get your mission critical data back.

You may face any of the below problems, if your critical files are damaged on your Mac OS X hard drive:

When you open a damaged file, the application quits unexpectedly or crashes. Your system may also stop responding and you may need to do hard reboot.

The indexing failure occurs, while using:

Spotlight application under Mac OS X 10.4 Tiger and Mac OS X 10.5 Leopard.

Find By Content and Content Indexing in Mac OS X 10.3 Panther.

System hangs, freezes, and kernel panics if your system is having damaged system components.

You can find out the damaged files using any of the below methods:

Use an advanced and updated anti-virus software. Anti-virus applications can not check damaged or corrupted files. It makes them ideal utilities for discovering damaged files. If you are not sure about the location of corrupted file, scan the entire hard drive.

Use backup utilities to create backup of affected Mac OS X hard drive. The backup utilities show execution errors when you try to backup corrupted files.

The anti-virus application can not find corruption in system files. In case of corruption of system file, your entire Mac OS X system becomes totally unusable. In the absence of system files, your Mac system can not find required resources to boot and thus data loss occurs.

To perform Data Recovery Mac in such significant situations, you need to scan your hard drive using advanced and effective Mac Recovery Software.

The applications are particularly designed to offer easy and simple Mac Disk Recovery. They ensure safe recovery, through read-only and non-destructive conduct.

Stellar Phoenix Macintosh Data Recovery software recovers deleted, lost, inaccessible, and missing data from Mac-supported storage media. The software with interactive graphical user interface works well with Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. It supports recovery from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

Mac OS X Leopard 10.5.6 Updates Render Time Machine Backup Unusable

madisonwalker — Mon, 10 May 2010 04:56:53 -0800

Mac OS X is a powerful and stable computer operating system, developed and marketed with Apple Inc. The operating system has various versions, which include Mac OS X 10.5 Leopard and 10.6 Snow Leopard. Apple periodically releases updates to make the Mac OS X operating system more advanced and powerful. The updates can directly be downloaded form Apple's website and install to your system. However, in some cases, the updates make some of Mac features unusable and sometimes even make your system unusable. This behavior leads to critical data loss and requires Mac Data Recovery to be sorted out.

One such update is released by Apple in the form of Mac OS X 10.5.6. The update is for Leopard users. This update is recommended for you to improve the security options and performance of your Mac OS X Leopard. It also includes enhanced graphics options for APERTURE, iChat, iTunes, and Cover Flow.

Instead of having some chiming notes for you, it has been observed that this update may affect the process of Time Machine in one way or the others. After installing the updates, Time Machine does not work for creating backup of your valuable data and restoring data from the backup. So, if you remove any file from your Mac OS X hard drive or you face data loss due to any other reasons, you can not look for backup. The only way, which is left for you, is to go for Mac Recovery Software solutions.

The data backup and restore process of Time Machine utility is based upon MAC address (it is a unique identity assigned to the network interface cards or network adapters). This address is stored in root of the Time Machine drive. The update changes the method in which the permissions are read from file or a file is modified in any way.

When such situations occur, you cannot restore your lost data from backup, even if you have an updated and valid backup. At this point, you need to perform Data Recovery Mac using commercial applications to retrieve your lost data.

The Mac Disk Recovery applications are specifically designed to scan affected hard drive using advanced scanning techniques and extract all lost data from it. They have interactive user interface to offer quick and simple recovery.

Stellar Phoenix Macintosh Data Recovery is the most comprehensive utility to ensure absolute recovery in all data loss scenarios. It is suitable for recovering data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. The software is designed for Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther.
