Disk initialization – prevalent data loss cause in Mac external drives

Posted in Mac Data Recovery by MacGuru – Be the first to comment

When it comes to data recovery Windows users face far fewer challenges than owners of Macs running Mac OS X This is because the Mac process of formatting a disk is actually three steps as opposed to Windows one. These steps are disk formatting, disk verification, and disk zeroing. During the process involved any number of errors can occur that result in lost data. Disk Initialization is the dominant data loss threat in Mac external drives. This destroys a Mac user’s critical data. Partitions that held your data appear to have vanished and Apple’s Disk Utility prompts you to reformat the drive. people tend to react to these prompts without being aware of the circumstances. When you connect a fully loaded external hard drive your Mac OS X pops up the disk initialization screen and leads you towards trouble.

A series of questions occur to you.

The immediate corrective actions to rescue your lost data?

What caused this unexpected data loss?

Is there a Mac recovery software program that can solve this problem?

The majority of OS X users attempt to resolve the problem using Disk First Aid. Usually this fails and presents even more error messages such as:

Verify and Repair Volume ‘disk1s3’
Checking Journaled HFS Plus volume.
Invalid B tree node structure.
Volume check failed.

The reason for this is as unclear as the effects of the data loss itself. At low level (file system), causes may be summarized as follows,

Corruption in partition table, which leads to inaccessibility of logical volumes to Mac OS X.

Catalog B tree Corruption in HFS Plus or HFS X volumes. etc.

However, if the data lost is crucial and it is essential to find a way to recover Mac files, one must find a a non-destructive, systematically working easy user interface recovery utility.

Disk Doctors Mac Data Recovery Software is equipped with a highly sophisticated scan algorithm to handle such situations. The programs powerful scan engine performs exhaustive systematic search in the corrupted HFS+ / HFSX file system, sector by sector, to reconstruct your lost Mac partition. The intricate and advance data excavation methodology recovers data with ease and returns toe disk to the original condition that existed prior to disk initialization.

The demo version of Disk Doctors Mac Data Recovery Software is free to use and can be used to evaluate the results that the full version will deliver.

Recover data from repartitioned Apple Mac drives

Posted in Mac Partition Recovery by MacGuru – 11 Comments

As with any operating system accidental partitioning or repartitioning is one of the most catastrophic data loss causes affecting Mac OS X users. I t makes no difference whether you have a desktop or laptop Mac or even a Mac external drive it is far too simple to accidentally reinitialize a Mac hard drive.This drastic situation can occur in many ways such as:

Unfamiliarity with usage of Apple’s disk utility resulting in deletion of files and reformatting of needed sectors.

Having similar storage media connected a single Mac machine, which might lead to wrong drive selection for partitioning.

Sabotage, malware, viruses etc

All of these above-mentioned instances rewrite the partition table contents with a new volume scheme in the storage media (hard drives, USB drives, smart cards) eventually leading to loss of the previous partition(s). Invariably the most valuable data held by previous partitions is lost. The volumes now mounted are newly created partitions, and crucial data which once existed is now presumed lost forever.

In such hazardous scenario, most of us would try to think of software that could rescue the precious data and return it to exactly where it was place prior to partitioning.

This powerful Apple Mac recovery software is equipped with distinct search algorithms for “lost partition finding from reformatted drive” and “data excavation from lost partitions” which can recover data from lost partitions even in case partition table scheme changed. This non-destructive recovery software works on Mac OS X 10.4 or later on both Power PC and Intel based platforms. A free demo version of Disk Doctors Mac Data Recovery Software is available to use and can be used to evaluate the results one may expect from the full version.

Data Loss on Mac OS X, is it possible?

Posted in Mac Data Recovery by MacGuru – 1 Comment

Data storage today has evolved to become an integral part of the mainstream of all corporate networks, government organizations, law enforcement agencies and even SOHO users. The need, defined at different levels for different users, is expansive from a small home user requirement to thriving data needs for high-end business environments.

Managing data from storage devices becomes mandatory without making any compromises for data being lost. In spite of having security at file system or at the OS level (password protect and back up mechanism provided by different applications), implementing backups, creating risk reducing RAID arrays, installing anti – viruses no system has been able to overcome loss of critical data Data loss can be caused due to various reasons,

  • Hardware/ Software Malfunction
  • Human Errors
  • Sabotage
  • Natural disaster
  • Ageing of storage devices
  • Mishandling of storage devices

Data Loss can be further sub-divided in two categories

Physical Data Loss: When the storage device encounters electronic or mechanical failures causing it to become dysfunctional makes it physically crashed. Such storage devices require expert hand and powerful data recovery services.

Logical data loss : Logical faults can occur due to human errors or software and hardware malfunction, which includes:

  • Intentional and unintentional deletion of data
  • Formatting and reformatting of partitions
  • Accidental partitioning or repartitioning of logical drives
  • Virus attacks
  • Sabotage
  • Power surge
  • OS faults
  • Read/ write errors and many more.

One would think that most Mac OS X users would anticipate the circumstances of data loss and take precautionary measures such as:

  • Data Backup
  • Protection from virus, spyware and malware programs
  • Data encryption
  • Limit access privileges in case of multi users
  • Regular defragmentation.
  • Restricting unwanted services
  • Provide backup for power surges.
  • Enhanced security level etc

However, many OS X users might not have any data backed up or salvage precautions, which eventually will raise the requirement of Data Recovery Software. Positive results are obtained in this area when we choose the best OS X data recovery software available. The recovery process should be carried out in a systematic scanning methodology, designed with intricate algorithms to deliver completely successfull recovery results.

Disk Doctors Mac Data Recovery is one of the few Mac Data Recovery software with a powerful file scanning and data recovery engine that is robust enough to excavate lost data from almost any type of logical data loss circumstances.
