Is your Time Machine backup locked after you repair your Mac OS X computer? Are you unable to access data from Time Machine volume? Does you Mac OS X computer starts creating fresh backup automatically when you connect your external Time Machine drive to system? This behavior usually occurs due to permission issues in Macintosh machine. The permissions are either damaged or missing. At this point, you need to format your hard drive to fix the problem. However, it removes all the data from hard drive and cause serious data loss situations. In order to recover your valuable data, you must opt for Mac recovery solutions.

When you backup volume gets locked, the Time Machine icon is replaced with simple volume icon with a small lock on it. In such cases, the volume can not be mounted and you can not access data stored on it. In case the volume is mountable and you attach it to a newly installed Mac computer, the same problem occurs with this computer as well. Your system drives get locked and it become totally unusable...

Are you unable to access your external FireWire derive on Mac OS X operating system based computer? Cannot you mount the external hard drive after changing permissions to “no access” through “Get Info” window? This behavior of Mac OS X hard drive renders all your valuable data inaccessible and you come across serious data loss situations. The problem may occur due to improper modification of access permissions of the hard drive. In such critical situations, you need to opt for Mac recovery solutions, if there is no backup in place.

Changing your access permissions to no access is quite light protection as you can switch to access mode by using “Get Info” window. However, in some cases, the mount process does not work on such a drive that needs to be mounted first before you try to access your significant data. In such cases, some of the Mac users try to clear up the disk permissions and then mount hard drive. You can remove permissions using the following commands on Terminal:...

Mac OS X hard drive is divided into various partitions, called volume, for effective management of your precious data stored on it. Every Mac computer has a boot volume, which contains critical system files that are required for your Mac OS X operating system-based computer to boot up. These files are pretty important for booting up your system. In case the boot partition gets damaged or deleted, your system become totally unbootable and unusable. It leads to severe data loss and require Mac drive recovery solutions to fix the problem, if there is no backup in place.

The boot volume of your Mac OS X operating system contains the following files:

Mac OS X operating system.

MBR (Master Boot Record).

BootX, Mac OS X boot loader.

Operating system kernel.

Binary files that are required for multiple kernel extensions.

Mach/BSD data structures.

Input/Output Kit.

Init, Mach bootstrap (service naming) daemon...

Mac OS X operating system uses numerous files and data structures to carry out different tasks. When you boot your system, it uses a number of files to perform specific operations, like boot loader to load operating system in main memory. If your system does not boot properly, you can use boot disk of Mac OS X operating system to fix the issues. It helps you to get into troubleshoot mode and replace the missing or corrupt system files. However, in some cases, the system stops responding while booting from a boot disk of Mac OS X. In such cases, the problem remains unsolved and your system becomes totally unusable. At this point of time, you are required to carry out Mac data recovery to get your mission-critical data backup, if there is no backup in place.

When you system hangs up while booting from installation disk of Mac OS X operating system, you may also encounter kernel panic error message, which resembles the following:...

Mac OS X includes a number of system files or directories, under the '/root' directory. The operating system assigns a specific operation to every directory or file. Mac OS X adapts UNIX file structure, which is totally unfamiliar to to MS OS users. Among all the system files, /library file is a significant one. It stores all your significant system files on your hard drive and essential to boot up your system properly. However, if the file gets damaged, you may not boot up your system. This behavior renders all your mission-critical data inaccessible, leading to critical data loss situations. In such cases, you need to opt for Mac recovery solutions to get your mission-critical data back.

The library file is one of the most significant files of Mac OS X operating system, which includes shared libraries, system files required for Mac OS X operating system to function effectively, including preferences, settings, and other requirements. Mac OS X operating system also have Libraries folder in the home directory that stores files that are specific to particular user...

Mac OS X supports external USB and FireWire hard drives to store your data, create backup, or even install an operating system. You can access data from external hard drives by simply attaching them and mounting them. However, in some situations, an external hard drive is mysteriously un-mounted by Mac OS X computer, while storing data to or accessing data from the drive. This sudden behavior of Macintosh operating systems makes your hard drive inaccessible and cause critical data loss situations. In order to get your valuable data recovered in such cases, you need to go for Mac data recovery solutions, if there is no updated backup in place.

When a Mac OS X external hard drive is un-mounted automatically, you do not hear any sort of strange noises. It means the hard drive is physically intact and in working state. When you attach your external hard drive to Mac OS X computer, you come across either of the below error messages:

“Mount: wrong FS type, bad option, bad superblock on /dev/hdb1,...

Hard drive inconsistency and integrity problems are very common in Mac OS X operating system. To handle such problems up to an extent, Mac OS X operating system provides you an inbuilt tool, called Disk Utility. It verifies your hard drive and repairs the damages in some situations. The utility can be run from boot disk of Mac OS X operating system. You can run this program even on the live hard drive. This process is known as Live Verification. However, in some situations, Live Verification of Mac hard drive may cause serious problems that lead to hard drive failure and data loss. At this point of time, you need to go for Mac recovery solutions, if there is no valid backup in place.

You should keep the below things in mind while performing a Live Verification of Mac OS X had drive:

The Live Verification works only on Journaled volumes of HFS+ file system. If you try it on non-journaled volumes, you may get an error message stating: “ERROR: could not freeze volume (Operation not supported).”...
