Mac Data Recovery after OS Corruption

While trying to start your Mac machine, “Are you getting a gray screen or kernel panic message or a blinking folder with question mark or a broken folder icon?” This indicates that your computer is not able to boot to the operating system files, therefore not letting your Mac machine to start up.

This may be due to a simple issue like faulty hardware, wrong setting, software conflict, incorrect boot sequence or due to system update, which you can manage to fix yourself. But if it is a severe corruption, then it is a clear indication that your operating system may have gone corrupt and must be re-installed to fix the problem.

Causes that leads to data loss after Mac OS X corruption

  • Bad Sector in Hard Disk – If there are bad sectors i.e. physical damages on the hard drive, then this may cause frequent system freezes and further use of the hard drive will cause more damage to the hard drive. On worst cases it will corrupt the OS files causing disk boot failure, hence making your data inaccessible
  • Virus Attack - Virus infection is another main cause of OS failure. That is if a malicious virus gets into the boot sector then it will corrupt the operating system files. In such cases, operating system needs to be re-installed, erasing all your important data
  • Power Failure – Frequent power outages causes system to shutdown improperly, resulting in corruption of file system structure of your Mac machine. Thus requiring re-installation of the Mac OS X
