Four Basic Reasons of Data Loss in Mac

Mac OS X has its roots in UNIX with a different code-base from the one seen in the original Mac OS. It comprises FreeBSD-based services and a Mach 3.0 microkernel. It uses HFS+ as the default file system since inception. Because of the underlying UNIX architecture and ‘Apple-like’ interface, it has been a personal favourite platform of many Mac geek and home users. With OS X, Apple has provided an additional level of usability by going past its ‘proprietary machine’ image in the marketplace. Macs are now compatible with a majority of applications and can even run Windows on the same machine.

With that said, Mac OS X is known to be the most reliable platform. However, in reality, there is a little truth to this fact. Mac OS X, built on a rock-solid UNIX foundation, is still prone to kernel panics, OS X crashes, applications conflicts, and similar problems. As a consequence, Mac users face episodes of data loss quite frequently than expected. There are several situations that end up causing severe data loss on Mac OS X. Some of the common scenarios are discussed below:

Catalog File Corruption
Catalog files play a major role in Mac OS X. File Manager uses these files to order or sort files and folders containing your data. The nodes of catalog files contain pointers to specific files or folders. When the catalog files get corrupt, these files and folders become inaccessible.

Accidental Volume Format
Accidental formatting can make you lose every bit and byte of data on your OS X volume. Sometimes, formatting becomes necessary to get viruses or malware out of your system. Before performing a volume or disk format, you should always back up your data to a different media, such as external drive, USB, or CD/DVD.

Mac Partition Becomes Inaccessible
A particular volume on your Mac may become inaccessible due to either incorrect partitioning or disk corruption. The directory of your OS X startup disk may become corrupt causing unusual Mac behaviour and sometimes data loss.

Apple Partition Map Corruption

This disrupts the low-level organisation of data on the disk, which indeed causes massive data loss. When you run ‘Repair Disk’ function of Disk Utility, you will receive corruption errors.

In all the above cases, your data becomes inaccessible or practically unusable. In such situations, you should take help of professional Mac file recovery software. Using these utilities, you can fix disk corruption and get access to all your lost files and folders. Further, these tools are compatible with Mac OS X 10.8 Mountain Lion.
