Mac Drives

The modern Macintosh computers come with some version of Apple's operating system, OS X that can be installed on dedicated Mac partitions such as HFS (Mac OS Standard), HFS+ (Mac OS Extended), HFSX (Mac OS Extended with case sensitive file names) and AFS (Apple File System). Due to the fact that Mac computes have the same physical device for data storage called a hard drive, there is no significant difference in data recovery techniques when comes to repairing Mac drive or any other one with a different operating system. All differences are only on logical level, in the way how file structure is organized on the disk. So there are no extras for Mac enthusiasts in their data recovery disaster.

Has your Mac Hard Drive completely crashed?

If your Mac computer will not boot - do not attempt trying to bring it back "alive", when it's already dead, or you will just make the situation worse and increase the chance of degradation of the magnetic data layers on the data disks.
Instead, you need to remove the failed drive and take it for a free professional evaluation to LaptopData lab. For physically failed / broken drives we offer fixed price, i.e. you'll never pay a penny more. You may also go with the estimation service and see the top price to expect for data recovery. And at last, but not least our rates are ultra-competitive – it's down to 50% less than any of our competitors with the same expertise niche.

Apple Stores quiet often refer their customers to our service, when the logical level recovery just won't do to get off the data of the failed medium. If that so, please remind Apple's technicians to remove the drive from the computer. Here, at LaptopData we need the bare drive only to start the data recovery process.
Useful info:The drive's damages can worsen over time, i.e. sooner is always better. Time is the importance - ask the service manager at Apple Store to expedite the removal of your drive, so it can be delivered to LaptopData Lab.

Windows on MAC and Apple computers with Intel processors


Mac with Intel Processor inside

Apple discontinued the use of its own PowerPC microprocessors in 2006. Since then, all Macintosh computers have x86 processors made by Intel and able to run Microsoft Windows operating system, without any emulation! Boot Camp software from Apple allows owners of Intel-based Macs to install MS Windows.

We will be happy to help you in extracting data files from any faulty, or broken Apple computer's drive. New and old devices are all supported for repair and recovery.
