When Mac hardware fails, not all is lost. Theres’s actually an excellent chance that a professional can recover the data using HDD recovery techniques. However, you must act quickly and appropriately. It’s important to note that mac data recovery is different from PC recovery, and it presents its own set of unique challenges. You don’t simply want a data recovery specialist. You want someone who specializes in mac data recovery.
So what makes Mac data recovery different from recovery on PC? Well, there are the architectural differences, but more importantly, it’s the difference in the file system structure, which dictates how your computer stores data on the drive. The Mac uses the HFS file system, which is quite different from the FAT and NTFS formats that are prevalent on Windows-based systems.
Since PCs are more widely used than Macs are, most data recovery engineers specialize in techniques best suited to that platform. However, HFS calls for very different strategies most of the time, and if the engineer does not employ them, it greatly diminishes the chance of data recovery. This problem is especially evident at local computer repair shops where expertise is limited and the majority of the business is PC-based.
If you should experience data loss on your Mac, it’s important that you stop using the computer and shut it down completely if it has not shut down on its own. If it has shut down, do not power it back up under any circumstances. If the hard drive is even marginally useable, doing so can make Mac data recovery more difficult, meaning more expensive, or altogether impossible.
Also, make sure to disconnect the computer from its power source, including the battery if it’s a laptop. This is especially important if there has been water damage. In addition, understand that not all data loss occurs during a catastrophic crash. In fact, the most common form of Mac data loss occurs when Mac OS X Finder is corrupted. When this occurs you will experience program crashes and corrupted data files, but the computer itself may seem relatively operational.
Do not use software-based solutions first rather than calling a professional. A professional data recovery specialist will be able to recommend the best solution to recovering your data. In some cases data recovery software will be able to recover the data and avoid using a data recovery service. Software-based data recovery works well in logical data loss scenarios and is caused by some minor corruption. The problem with using it if it is a physical loss, it can actually further obscure the data and make it more difficult for the data to be recovered.
