In computer, data recovery is a procedure of recovering (retrieving) inaccessible, lost, corrupt, damaged or formatting data from external storage devices, computers or other computers. Data recovery can be done through several ways. The most common method is to check if the data is still available using some special software. This is called “checksum recovery”. If the data is available, the hard drive can be read using this software. This will ensure that your data is still intact and safe.
Apart from checking if data is still available using this software, you can also check whether they are physically damaged or not. Physical damage is usually caused due to physical shock or impact. logical bad sectors in some of the external hard drives can also cause logical bad sectors in the storage devices. When this happens, the data files on these drives can become corrupted or inaccessible. Data recovery can then help you to restore your data files from these physical drives.
Other methods of data recovery software include ‘live cd’ programs. These programs are installed on your computer and it enables you to boot up from a CD when your hard disk is not working properly. Live CDs do not require installation of software as they come with an integrated operating system and all the software required by you is installed already. This software is similar to the installed program, just that it comes on the CD instead of an actual hard disk. After you install the software, it boots up and searches for lost partitions, deleted files or any other file loss.
Another data recovery software method is to create a backup disk image. You can make a backup disk image of your entire hard drive. When you backup the disk image, you can easily recover data files even when your storage devices are broken. The open-source CDR software can also be used to create a disk image.
You can also use ‘dde’ command in Windows to recover data files. When the logical failure occurs, a DDE will prompt you to select a recovery mode. If your storage devices have a Secure USB port, a DDE can access the storage device from the USB port without using a PC. You can also perform a DDE without any other storage device by connecting the data recovery software to a host computer.
Physical Damage Can Cause Physical Failure physical damage is also one of the major reasons why data recovery becomes complicated. When data recovery becomes complex due to physical damage, you cannot just pull out the storage media and use it again. If the damage is far too extensive, it will be impossible to retrieve important data. Even if you manage to pull out the media and restart the system, the recovered data may be stored on corrupt storage media. Physical damage comes in different forms such as logical damage caused due to accidental deletion or file system corruption, physical damage caused due to fire or flood, physical damage caused due to sabotage, and so on.
How to Perform Mac Data Recovery If you are planning to perform data recovery on Mac OSX operating system, you can use a disk cloning software program to clone your hard disks. The disk cloning software programs are available for both MAC and PCs. They are a little bit different from the standard disk imaging software. With the standard disk imaging software, you can only clone one disk at a time. But with disk cloning programs, you can clone multiple disks. You can even copy data to different disks at a time.
One of the main advantages of these programs is that they allow you to copy data to regular hard disks and then copy the data to USB flash drives. This helps you to easily recover the data from all types of storage devices including, Mac Os, iPhones, computers, laptops and other storage devices with USBs. If you want to perform data recovery for Mac, the best solution is to invest in the right disk cloning software program.
