Data loss reasons and recovery solution in Macintosh operating system

Mac File RecoveryMacintosh is considered to be most important and complicated operating system developed by Apple Inc. This is one of the modern operating systems facilitating its users with all the advanced features.

Local File systems used by this operating system are UFS (Unix File System), UDF (Universal Disk Format), HFS (Hierarchical File System) and HFS + (Hierarchal File System+). These file systems are based on some of the enhanced features for the management of tasks to be performed by operating system and ultimately providing ease to the Mac user.

This Apple Mac OS is prone to too much damages, although it is designed keeping in mind all its major aspects of security. Mac file system suffers from many physical and logical damages due to fire, flood, power surges, virus attack and human error. They affect the normal working of operating system.

In most of the scenarios damage to operating systems result in loss of some of the important files and folders. It creates great panic and frustration for the user.  Other major issues which lead Mac OS to data loss situation are listed below:

One of the major parts in data loss is played by some viruses, which attack directly at low level of the file system and duplicate all the content saved in the data files. In addition, it disturbs the whole working of the operating system.
If machine was not properly shutdown then some of the data files might be deleted and inaccessible.
Some of physical damages caused by fire, water and moisture exposure damage not only the system but also most of the data files, which can only be recovered by data recovery specialist.
Mac OS does not work when volume header is corrupted.
Corruption of partition table.
Failed master directory block does not initiate certain files from being opened.

Some of the logical faults can be overcome using efficient and best data recovery software. Data lost from physically damaged systems needs to be recovered from a professional data recovery service provider.

Mac File Recovery

Mac is a series of personal computer designed, developed, manufactured, and marketed by Apple™ which uses its own designed and developed operating system called MAC OS. The original Mac used “Motorola” and “IBM” processors, however recently they have launched their new hardware based on Intel x86 processors. The Mac OS which is used natively on Mac hardware was originally known as “System Software,” the current version of Mac OS is Mac OS X which has been code named like puma, jaguar, panther, tiger and leopard.

Mac OS X saves data using HFS and HFS+ (Extended and Journaled) file system; like all other platforms, Mac users also face data loss, some of the most common causes for data loss which are supported at Disk Doctor Labs have been indicated below.

What are the Symptoms of a Data Device Failure?
Your data device might be displaying any one of the symptoms listed below. This can be due to physical damage to the storage device or logical corruption to the file system or operating system. Below, we have listed many of them.

• Mac Machine won’t boot
• Clicking sound heard from device
• Hard disk drive not spinning up
• Electronics controller card is damaged
• Smoke was observed / smelled
• Virus attack has corrupted the file system
• Accidentally deleted files / directories
• Accidental reformatting of partitions
• Missing or deleted partitions
• Applications are unable to run or load data
• Device firmware has become corrupt
• Hard disk drive components failure
• Fire or water damage
• Inaccessible drives / partitions

What are My Data Recovery Options?
Disk Doctors’ has been serving Mac users as well as printing, graphics design, animation, and entertainment industries that mostly use Mac platforms.

If your device has displayed any of the symptoms listed above, then you may consider any of the following recommendations.

DIY (Do It Yourself):
Although data storage devices in most of the Mac laptops and desktops are not easily accessible, but if one is technically savvy and comfortable in handling the data storage devices, and sure about physical fitness of their data storage device, then they can download demo versions of recovery software to determine whether the issue could be addressed using a recovery utility before spending money to purchase the software. If this helps, then more power to you.

Note: Data storage devices in most Mac machines are not easily accessible; and any attempt trying to get the hard disk drive out may result in unnecessary damage to the machine itself. Therefore, we do not recommend this solution to most; as we have observed the situations getting out of hand while attempting DIY quite often mostly due to inexperience. And often destroying any chances of future recovery attempts.

Get Professional Help:
If your data is vital, then seeking professional help to recover is the only way to go about it. Professional help includes only well established and reputed data recovery companies with a proven track record.

How Much Data Recovery Would Cost?
The recovery cost for a single Mac hard disk drive with HFS or HFS+ can run a wide range (anything from $350 to $3000 depending upon the nature of problem).
