How Can We Recover Mac Lost or Deleted Files Easily

Recovering deleted data from a Mac OS X hard drive is generally possible because typically the actual data is not deleted. Instead, information about where the data is stored is removed. In this article I will explain how data is stored on a hard drive, what happens when files are deleted, what formatting a hard drive does, and why it is impossible to recover files after they were overwritten.

If you are interested in the organizational structure of a hard drive, please read this article then you will find something you need. For more information on how to recover deleted files, see the resources at the bottom of this article.

How Is Information Stored Digitally?

Digital information is stored in bytes. Each byte contains 8 bits. Each bit has a value, which is either 0 or 1. This way of storing data is called the binary numeral system as it uses two symbols, i.e. 0 and 1. Subsequently, any data stored on a computer is written in the binary code, which is a string of 0s and 1s.

What Happens When Data Is Deleted?

In a RAM module, the organizational structure is very flat. When data is removed from memory, the actual information vanishes instantly. Also, when power is lost, the capacitors quickly discharge and hence all information is lost.

The situation on a hard drive is completely different as information is stored in two ways. First, data is stored physically on the magnetic hard drive. Secondly, all stored data is managed by a file system, which creates an information table revealing the exact location of data, i.e. where on the hard drive a certain file is stored. This is necessary because one file can be stored in different locations across the hard drive. The operating system then uses this table to locate files and put together the pieces of large files.

When a file is deleted, typically only the information stored in the file system’s table is removed. Since it would take too long to delete the actual file, the physical location of the data remains untouched. When the operating system wants to store new files, however, it consults the table for available space. Since the location of the deleted files was marked as vacant, the operating system may then write new data over the old data, which terminally deletes that information.
