Data Recovery From Mac OS X Systems

Mac OS X is a 32 or 64 bit multi-tasking Unix like operating system, the latest version of the Apple Macintosh operating system, designed to run on apple’s own Power PC processor architecture. First commercially released in 2001 there have been 4 major releases of OS X, the latest being OS 10.4 codenamed Tiger. The OS itself consists of two main parts: Darwin, an open source Unix like environment which is based on Mach microkernel/BSD Unix and the GUI (Graphical User Interface) ‘Aqua’ developed by Apple.

Although OS X is built on the stability of Unix, and the hardware used by Apple tends to be of a high quality, mistakes, accidents and hardware failures do happen, an Apple system is just as prone to data loss as any other system. These types of failure can include:

Hard disk failure (see General Hard disk Failure section of Data Clinic website)
Degradation of hard disk or peripheral media (including Floppy, CD, Zip or external hard disk etc.)
User Error (accidentally deleted data etc)
Accidental initialization or formatting of media
File system corruption
Malicious damage and more

Recovery of data from an OS X system requires an in-depth knowledge of not only how the operating system is put together but also and perhaps most importantly, how the file system at the core of OS X works. OS X uses as standard one of two completely different file systems, HFS+; the latest development of Apple’s proprietary Hierarchical File System, and UFS a true Unix file system.

Data Clinic have developed custom tools and solutions for every type of Macintosh data loss situation:

File system corruptions.
Incorrect Kernel commands leading to data loss.
Incomplete File Vault operations due to power failure or system crash.
Recovery of external media using other file systems. eg FAT32 formatted external hard disks.

*** It is even possible in rare cases to recover data from an OS X system where the files in question have been deleted using the Finder’s Secure Empty Trash facility, this is however dependant on the type of data that is to be recovered. Please ask to speak to a technician for more details on this process.***

*** Data clinic can also recover data from Linux/Unix distributions compiled for the PPC (Mac) architecture, should you require help with this kind of system please contact us on the number below and ask to speak to one of our Mac experts. ***

Mac OS X is the most widely used of the Unix-like operating systems on the market. Although marketed as version 10 of the Mac OS it is a move away from traditional systems and is actually a culmination of MAC OS and NeXTSTEP operating system. NeXTSTEP was also based on the same Mach kernel which is such an integral part of OS X. The OS X architecture is so radically different from previous MAC releases that programs compiled for earlier releases have to be run in emulation known as Classic.
