In Mac OS X and all other UNIX-based operating systems, you can easily create backup of your critical data by creating the disk image through DD command. It is a command-line tool that creates a bit-by-bit image of entire hard drive on desired storage media. You can mount the disk image as a hard drive volume and access data from it. However, in some situations, the disk image can not be mounted and stored data can not be accessed. In such situations, you are required to opt for Mac Data Recovery to get your mission critical and valuable data back.
Generally, to create the disk image, your hard drive from which you are copying the files, needs to spin. What if the hard drive can not be mounted or accessed? As long as the drive spins, DD command can help you get out of trouble, even if the drive is physically damaged.
After creating the image of damaged or inaccessible hard drive, it is possible to quickly and easily restore data. The disk image is used as a backup of the original hard drive. After repairing or reinstalling the Mac OS X operating system, backup copy can be used for restoring data and making your system functional again.
It is quite easy, safe, and quick to perform Data Recovery Mac in case, any disaster happens. However, under some circumstances, you can not use the disk image created using DD command. For example, you may come across the underwritten error message when you attempt to mount disk image for accessing stored data from it:
“No mountable file systems”
The above error message renders all your critical data from the disk image inaccessible and leads to significant data loss situations. Data loss is something that can not be accepted in any case and you need to opt for recovery solutions to get your valuable data back.
You can recover lost Mac data in such cases through commercial Mac Recovery Software. The applications are specifically designed to carry out in-depth scan of entire hard drive and extract all lost, missing, and inaccessible data from it. The Mac File Recovery tools have simple, self-descriptive, and rich graphical user interface to ensure recovery in most of the logical data loss situations.
Stellar Phoenix Macintosh Data Recovery is the most advanced solution for all Mac data loss scenarios. It recovers lost data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes. The software is compatible with Mac OS X 10.6, 10.5, 10.4, and 10.3.9.
