Why Hard Disk Data can be Recovered?
To get back lost data from Mac hard disk is possible because of data remanence, which means that some data continues to exist on the hard disk drive even after it has been deleted. While data remanence is beneficial to hard disk recovery, there is also a downside; that is, data remanence is one of the most convenient tools used in cyber-espionage. That’s why computer security experts tell you that simply erasing a file doesn’t always completely delete it.
The best hard disk data recovery software-uFlysoft Data Recovery, reconstructs lost files, regardless of whether they were deleted accidentally or are inaccessible due to a crashed hard drive, hardware failure or virus infection. In some circumstances, the hard disk may become inaccessible because of a hardware problem. The actuator arm, a small mechanical arm that moves back and forth across the hard disk, may have suffered a mechanical error. In this situation, the data is not lost at all, but is just inaccessible due to this hard disk mechanical problem. Similarly, the circuit board may develop flaws, which may make the hard disk inoperable. If there are strange noises or no noise at all, the cause is likely mechanical, and a technician will have to disassemble the hard drive to repair the problem. In some cases, the mechanical problem may cause the drive itself to become damaged, which may directly affect the data. Alternatively, data loss may occur due to a software problem.
Taking a little preventive action can help prevent the need for Mac hard file data recovery. When files become fragmented, they are stored in multiple clusters on the hard disk drive, which makes the computer take more time to read it. A drive with a lot of fragmentation will be harder to recover in the event of a crash. Therefore, it is recommended to regularly defrag your hard disk drive.
When a file is deleted, the operating system marks the file name with a character that informs the computer that it has been deleted. The deleted data is actually still on the hard disk drive until the file system overwrites it, but the operating system can no longer access it. The process of hard disk recovery finds the data that the operating system is unaware of, but still exists in individual clusters on the hard disk drive. However, clusters that have become corrupted or physically damaged cannot be recovered. In these cases, hard disk recovery has a greater likelihood of success if it is attempted immediately after the failure so as not to give the sectors with missing data an opportunity to be overwritten. A professional hard disk recovery service will not work on the hard drive itself, but will instead make a sector copy of the hard drive and work from that.
3 Easy Steps to Recover Lost Data from Mac Hard Disk
With uFlysoft Mac Data Recovery, a crashed hard disk drive is not the end of the line for your Mac. We specialize in safe and secure hard disk data recovery and data and file extractions from hard disk drives. Hard disk data recovery is our primary focus.
If you are having hard drive problems, it’s important to let a professional handle data recovery so further damage is not done to the hard disk, making data or file recovery impossible.Without further ado, let’s just follow the steps below to recover lost files from Mac hard drive with ease.
1. Install this free download data recovery software on your Mac;
2. Launch the program and choose the hard disk where your lost flies were stored before and start scanning;
3. After scanning finished, you can preview your lost photos files, you can choose which you want to get back and then click “Recover”, you will find the lost photo files coming back to you again in a while.
1. Pay attention, don’t save the recovered files on the same path where your lost files were stored before or you will lose them forever because of the data overwritten situation.
2. Remember, after recovering is finished, build a backup for your data is strongly needed.
