Steps for Successful Mac Data Recovery

Hard drive failure and data loss is a horrifying reality for computer users around the world. Even the most stable and reliable operating system – Mac OS X fails at some point of time. System failure can be either due to logical or physical reasons. In both cases, you lose access to your precious data and encounter data loss. Data loss is something that greatly harms your business as well as personal life. In all such cases, you must restore data from an updated backup to save your business. However, if the backup is not available, you need to carry out Mac Recovery to get your valuable data back.

In order to ensure absolute recovery of lost data from Mac OS X hard drive:

• Check the type and cause of problem – You must first analyze what is causing the problem. If your system is inaccessible due to file system corruption, missing/damaged data structures, and other related problems, it is logical failure. On the other hand, damage to mechanical and electrical components of hard drive indicates physical failure.

• Check hard drive consistency and integrity – Use Disk Utility or ‘fsck’ to detect and fix hard drive errors. These inbuilt utilities of Mac OS X operating system detect and repair errors on Mac OS X hard drive.

• Format the hard drive and reinstall operating system – If disk repair tools can not help you detect and fix hard drive errors, replace damaged data structures by formatting the hard drive and reinstalling operating system.

• Restore data from backup- Hard drive formatting removes all the data from Mac OS X hard drive and causes further data loss. In such cases, you need to restore lost data from a valid and updated backup.

• Use third-party recovery applications- If you are unable to restore data from backup or the backup is not available, it is time to use commercial Mac Recovery Software.

Such utilities are specifically designed to carry out in-depth scan of whole hard drive using powerful scanning algorithms and perform Data Recovery Mac in a perfect manner. They ensure easy ‘Do It Yourself’ Mac Data Recovery with self-descriptive and interactive user interface. They preserve integrity of your valuable data due to read-only behavior.

Stellar Phoenix Macintosh Data Recovery is an excellent solution for all your Mac data loss problems. The software can be used 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.

How To Recover Deleted Files Trash Mac?

Have you deleted an important file from your Mac OS X hard drive and then realized its importance? Is the Trash Bin empty and it does not contain the files that you recently deleted? The unexpected file deletion is something that happens with most of the computer users. After emptying the Trash Bin folder, you need to restore the file from backup. However, if the backup file is not usable or its not updated, Mac Data Recovery is the only way to get your precious data back.

When you empty Trash Bin in Mac OS X operating system, it gives an error message, which states:

“Are you sure you want to remove the items in the Trash permanently?”

While this Mac warning message means that all the files that you are removing from Trash folder cannot be recovered using any manual method, unless you have a complete backup.

What happens when you remove a file on Mac OS X hard drive?

If you think that the files are deleted forever, after you empty the Trash Bin, then you are wrong. Though, most of the user who do not know about the actual file removal process, think that emptying the Trash removes file permanently, but this is not the fact.

Files are never deleted from hard drive when you empty Trash Bin folder or individually remove the files from Trash. The operating system simply loses the access of the file, as the pointers between files and file system index are deleted. The space occupied by deleted files is marked as available and can be used to store new files.

The deleted files remain physically intact on the drive until they are overwritten by other files. It is possible to recover the lost files, after emptying Trash Bin folder. Recovery is possible through advanced third-party applications, known as Mac Recovery Software.

The applications are incorporated with high-end scanning algorithms to carry out methodical scan of whole Mac hard drive and extract all lost, missing, and inaccessible data from it. These tools allow you to perform Data Recovery Mac on your own, without demand sound and prior technical skills. The Mac Recovery utilities do not alter original files and their contents as they perform safe recovery with read-only and non-destructive conduct.

Stellar Phoenix Macintosh Data Recovery software ensures absolute recovery of all your lost files, directories, and hard drive volumes. The software supports recovery from Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther-based hard drives, USB drives, FireWire drives, memory cards, and iPods. It works on HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

Mac Disk Utility Program Fails to Recover Lost Files

Is your Mac OS X hard drive damaged? Do you need to format or repartition the hard drive? If ‘Yes’, Disk Utility is the tool that can help you. It is an in-built tool of Mac OS X operating system, used to perform hard drive-related operations. It enables you to create disk image, mount/unmount hard drive, enable/disable journaling, change/add partition table, check hard drive integrity, and repair damaged disk. The disk repair option of Disk Utility helps you to fix hard drive related errors, prevent data loss, and need of Mac Data Recovery solutions.

In Mac OS X 10.3 and earlier versions, you cannot use the Disk Utility to verify file structure of boot drive and repair directory structure of active startup disk. However, in Mac OS X 10.4.3 and later versions, Disk Utility can be used to verify the startup disk. In Mac OS X 10.5 Leopard, you can use this tool for live partitioning of hard drive. Live partitioning is the process of creating, resizing, and deleting the hard drive partitions without erasing them.

How to Repair Damaged Mac OS X Hard Drive Using Disk Utility?

Go through the below steps to detect and repair errors on your Mac OS X hard drive:

• Start your system from Mac OS X Install disc.

• Choose Disk Utility from Installer menu after your computer starts up from Install disc.

• Click ‘First Aid’ tab.

• Select the affected Mac OS X hard drive volume.

• Click Repair button. The Disk Utility checks and repairs your Mac OS X hard drive.

When you run Disk Utility on a damaged Mac OS X hard drive, it checks integrity and consistency of the hard drive and file system. If it detects any error during the course of action, it prompts you a message and tries to fix it.

However, in some situations, Disk Utility cannot detect and fix damage to your hard drive and you come across error messages, similar to the following ones:

“Disk Utility stopped repairing permissions on ‘(volume name)’ because the following error was encountered: No valid packages”

Or

“Verify volume failed with error could not unmount disk (-10000)”

In such cases, the disk cannot be repaired and you cannot access data stored on it. At this point, you need to perform Data Recovery Mac to retrieve your precious data.

Mac Data Recovery is potential through third-party Mac Recovery Software. The applications enable safe, easy, and absolute recovery in all cases of data loss.

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

Recover Lost XLSX Files from Formatted Mac OS X Hard Drive?

Microsoft Excel is a popular spreadsheet application, developed and marketed by Microsoft Corporation for Microsoft Windows and Apple Mac OS X operating systems. Excel For Mac, is a part of Microsoft Office for Mac. Likewise, Microsoft Excel 2008, is also a part of Microsoft Office 2008 for Mac, which stores spreadsheets with XLSX extension. To keep these critical files safe, you should regularly back them up. Taking backup is about creating an identical copy of your precious data, which helps you to prevent data loss situations and avoid need of Mac Data Recovery options.

The most common reason of losing XLSX files from your Mac computer is hard drive formatting. Formatting removes all the files, directories, volumes, operating system, and installed applications from the hard drive and make the drive completely empty. In such situations, you lose all your XLSX files, if you do not have an updated backup. Though formatting is frustrating at times (since it calls for creating, maintaining and updating backups), it is inevitable. You may need to format a Macintosh hard drive for any of the following purposes:

• To get rid of a deadly virus, which can not be removed using an anti-virus software.

• Replace damaged file system or hard drive data structures.

• Reinstall operating system to fix boot errors or restore missing system files.

• Remove all the files and folders from hard drive.

Although, hard drive formatting removes all the content of the drive, all of that content is still recoverable. It is possible to recover lost XLSX and other files after formatting a hard drive.

Disk formatting doesn’t remove the files, until they are overwritten by other files. Hard drive maintains an index file, which tells the operating system where a particular file is stored. When you format the hard drive, links between index and file are deleted. The file remains physically intact and can be recovered using Mac Recovery.

You can perform Data Recovery Mac in a perfect and quick way using advanced third-party recovery applications, known as Mac Recovery Software. The applications are powerful enough to carry out thorough scan of whole Mac hard drive and extract lost, missing, and inaccessible data from it. They are incorporated with simple graphical user interface and read-only conduct to offer easy and safe recovery.

Stellar Phoenix Macintosh Data Recovery is the most prominent tool that is used to ensure absolute recovery of your valuable data. The software supports Mac Recovery from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volume of Mac OS X 10.6, 10.5, 10.4, and 10.3.9 operating systems. It recovers all types of lost files, including XLSX files, multimedia files, documents, and more.

How to Recover Deleted Identity in Entourage?

Microsoft Entourage is a personal information manager and email client of Mac OS X operating system, developed and marketed by Microsoft Corporation. It is a module of Microsoft Office for Mac. It also provides support for Microsoft Exchange Server. It creates Identity to store your valuable data. The Identity feature enables various users to access emails, Contact information, and Task and Calender items in a uniquely configured and separate environment. However, in some situations, the identity may disappear or get deleted from the database. In such cases, you can not access your critical data from the Entourage database and face severe data loss conditions. At this point, Mac Recovery becomes essential to get your data back.

You can use the Identity feature of Entourage application when:

• There are various users who have different personal information and email accounts, which use same Mac computer. The scenario is pretty common for the users who share single Macintosh Machine.

• A user needs to separate his/her personal emails, Tasks, Contact informations, and Schedule from the items, which are related to work.

Location of user Identity in Entourage:

Microsoft Entourage application installs the MUD (Microsoft User Data) folder in User’s Document directory. Your Identity is stored in this folder. By default, ‘Main’ name is assigned to the Identity.

Under some circumstances, you can not see or access your Identity in Entourage application. The problem may be due to missing or deleted Identity. This situation may occur due to accidental deletion, virus infection, application errors, and other such reasons.

At this point, you can not access your emails, notes, contacts, tasks, and other significant data from Entourage application and need Data Recovery Mac. Following steps help in retrieving lost Identity:

• Restore from backup. If you have an absolute backup of Entourage database, restore lost or deleted identity from it.

• Recover lost Identity using third-party applications, known as Mac Recovery Software. Since Identity is a file, such tools can easily recover it.

The recovery applications employ high-end scanning techniques to carry out in-depth scan of entire Mac OS X hard drive and extract all lost, missing, and inaccessible data from it. They enable you to perform Mac Data Recovery on your own, without any prior technical skills.

Stellar Phoenix Macintosh Data Recovery is the most advanced and effective application that is used to ensure perfect recovery of lost data. It supports Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. The software recovers data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

Catalog Record Corruption May Cause Data Loss in Mac OS X

Mac OS X hard drives are generally divided into various volumes. The hard drive volumes may contain four types of items: files, file threads, directories, and directory threads. Every item is identified by the catalog record. Catalog records are formed in on-disk catalog B-Tree. The contents of a directory are derived by exploring the catalog B-Tree. However, if the catalog records are damaged, you can not access the file. Such situations may lead to data loss and will need Mac Recovery to recover all the lost data.

A Mac OS X file has the following two forks or components-

Resource fork- An indexed file that contains menu items, code segments, and dialog boxes.

Data fork- Contains stream of bytes.

Every component is made up of one or more contiguous runs or extents of blocks. Length and starting block of an extent is encoded by an extent descriptor in 32bit quantity. First extent record of every component is the part of catalog record of the file.

Along with the B-Tree extents and files, a Mac OS X hard drive volumes also include two boot blocks – volume information block and free space bitmap. In order to improve the crash recovery abilities, a remarkable amount of redundancy of disk data structures is maintained. While not necessarily the part of file system, several catalog records are reserved for exclusive use of the Finder application.

Each file and folder on Macintosh volume has a unique identification number. Still, files or directories are named by the identification number of their parent file or file name of the directory. This combination is used as a search key for catalog B-Tree of the volume.

Under some circumstances, the catalog record or catalog B-Tree may get damaged due to virus infection, file system errors, improper system shutdown, and other similar reasons. In such cases, you may encounter error message similar to the following, while trying to access the file:

“Message Catalog System: corrupt file”

This behavior may render the files inaccessible and need Data Recovery Mac to retrieve the inaccessible files.

Mac Data Recovery is possible using advanced and powerful third-party Mac Recovery Software. They carry out extensive scan of the affected Mac OS X hard drive volume and extract all lost, missing, and inaccessible files from it. The applications enable safe, quick, and easy recovery in all data loss situations.

Stellar Phoenix Macintosh Data Recovery is an excellent solution to ensure absolute recovery of your lost Mac data. The software is designed for 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.

Rectifying “Reserved fields in the catalog record have incorrect data” Mac Error

Is your Mac OS X hard drive not operating anymore? Is your computer unbootable or unresponsive? Such difficulties may occur due to catalog file related problems in Macintosh operating system. In such instances, your system may not boot and will not let you access the hard drive. Generally missing or damaged system files cause such troubles and lead to severe data loss situations. Restore data from the most recent backup to prevent data loss. However, if you do not have a backup copy of your significant data, Mac Recovery is the way to go.

In a practical scenario, you may encounter one or more of the below mentioned behaviors while starting your Mac OS X system or while working on it:

• The hard drive(s) are not functional.

• You get “Reserved fields in the catalog record have incorrect data” error message while starting the system.

• You encounter “The volume Macintosh HD needs to be repaired” error message while trying to repair hard drive using Disk Utility.

• When you run Disk Utility, it says that the disk can not be fixed.

• System shows memory issues and the hard drive volumes can not be mounted.

• You get empty blue screen at startup.

Irrespective of the symptoms and causes of these problems, it causes data loss. To get your mission critical data in such situations, find out the cause of this issue and solve it through Data Recovery Mac.

Root of the problem:

You may come across this after updating third-party disk management and disk repair utilities. It generally occurs, if the newer version of application is incompatible with the version of Mac OS X that you have currently installed.

Mostly this is due to corruption of the file system, catalog file, or other key data structures of Macintosh operating system. After corruption of system files and data structures, Mac OS X can not find the boot files and thus refuses to boot.

Solution

You can fix this issue by performing ‘Erase and Install’ in Mac OS X operating system. However, this also removes all the data from your Mac hard drive and causes further data loss.

To recover lost data in such cases, Mac Data Recovery is advised. The recovery process is quite safe, effective, easy, and quick through advanced File Recovery Mac Software.

Stellar Phoenix Macintosh Data Recovery software recovers lost files, directories, and volumes from Mac hard drive in all cases of data loss. It supports Mac OS X 10.6 Snow Leopard, 10.5 Leopard, 10.4 Tiger, and 10.3.9 Panther. The software recovers lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.

Interrupted Secure Erase Process Cause Data Loss in Mac OS X 10.4 Tiger

Mac OS X enables you to protect your significant files using FileVault to prevent unauthorized access. When you apply the FileVault protection for any user account in the Security Preferences, your whole home directory gets converted into encrypted disk image. In Mac OS X 10.4 Tiger, you can also safely remove data from hard drive using the FileVault tool. However, sometimes you may lose your precious data if the secure erase process is interrupted. Such circumstances create the need of Mac Recovery, if an updated backup is not in place.

You can securely erase your confidential data if FileVault protection is on by clicking “Use secure erase” check box when “You are now ready to turn on FileVault protection” dialog box is displayed. If you choose this option, don’t interrupt secure erase process, even if you see “Unmounting FileVault” for long time.

What is Secure Erase Process of FileVault?

After clicking “Turn On FileVault” with “Use secure erase” option, you are logged out of the account and FileVault windows appears. A status message indicates you how much time the encryption process will take. After completion of encryption process, secure erase begins, but it does not show any status message. It shows “Unmounting FileVault” message. This process erases all the files and they are removed after being copied to encrypted image of FileVault.

What Happens If you Interrupt the Secure Erase Process?

• You cannot log into your Mac OS X account, for which you enabled the FileVault protection.

• All the files in your Home directory, including the items that are on your Mac desktop, in Documents, Pictures, Music, Movies folders, Mail messages, application settings, and your bookmarks, may be lost. These items cannot be accessed even if you you log in using a different account.

Creating a backup copy of critical files or whole home directory, before applying FileVault protection, is a good idea to prevent data loss situations.

However, if the backup is not available, Data Recovery Mac is the way to get your valuable data recovered. You can successfully recover all types of lost files using Mac Recovery Software. The applications are particularly designed to carry out in-depth scan of entire Mac hard drive and extract all lost data from it. They enable you to perform safe and easy Mac Data Recovery.
