Data loss is an unpredictable event that always has deep consequences. First comes the panic, then the frantic efforts to recover data, quite likely destroying residual data in the process. Then the long process of recovering data but unsure of whether the data is usable or not.
At the most, data recovery is a risky business and has to be conducted in the most responsible manner possible, with all possible respect for the data that has been lost. There are ways to recover data on Mac computers depending on the reason for the data loss in the first place.
Data Lost During Disk Initialization
Mac uses several steps to format disks, such as disk formatting, disk verification, and disk zeroing. It is not unknown for errors to occur during this process, causing data loss. Disk Initialization is the dominant data loss threat in Mac external drives, sometimes destroying a Mac user’s critical data. You’ll have to invest in a good Mac data recovery software to recover data lost during disk initialization. One way to prevent this is to always back up your data on a daily or weekly basis, depending on your need.
System Data Corruption Leading To Data Loss
If the data structure of your system is corrupted, or if you upgrade your system, the Finder tool might stop working and throw up error messages that are hard to understand. This renders your volumes inaccessible, and results in loss of vital data. In this case you’ll have to restore the Finder using Disk Utility and restore data using a good Mac data recovery software.
Accidental Data Loss
This would be the most common way to lose data. Accidents occur every day in our lives. We sometimes delete data that might be important, without thinking. Data lost accidentally can be recovered if you take the right measures. However, even accidentally lost data cannot be recovered if too much time passes.
What Are Chances Of Data Recovery?
The first thing to do when you realize that you’ve lost data is to stop using your Mac immediately. This ensures that the space that was occupied by your deleted data is not filled up by any other information. As your Mac’s operating system doesn’t immediately re-use the space left behind from files are deleted, you can recover the deleted data in a few days. However, the likelihood of recovering deleted files successfully decreases the longer you delay, as some or all of that space will be re-used.
It all depends on how full your computer’s hard drive is. The fuller your drive, the sooner the free space will be used by other files. Also, chances of file recovery will be severely impacted if you have de-fragmented your hard drive after the file was deleted. It’s possible that during de-fragmentation, current files will have been moved into the free space left by deleted files in order to reduce fragmentation. This makes it much less likely that any undelete software will be able to find anything useful.
