About drives, partitions and security

Hard Drive is a physical device used for storage of digital data. Hard drive is capable of writing or reading data on a magnetic surface of several platters that rotate at very high speeds. All data written on any digital storage equipment such as hard drive is nothing but row of binary 0's or 1's. Hard drive partitioning is a process where a drive is separated into logical divisions, called partitions. Partitions are often used to offer easier management of user's data on a computer. For instance, a large hard drive can be separated into three partitions, first one will be used as a system disk (C drive) and it will contain Operating System and all installed programs and settings. Second one (D) could be used as a work disk, where a user put his documents, projects and related files. Third partition (E) could be used for backup, or for storage for multimedia files, audio and video files. If anything bad happens with one partition (unbootable, corrupted, broken mbr etc) others will continue to work, unless it is a hard drive physical failure. Hard Drive Eraser is used to erase partitions

Unfortunately, the nature of technology make is nearly impossible to erase the data beyond recovery, at least not without the specialized tools (such a Hard Drive Eraser is). You can always try to physically destroy hard drive, melt it, or degauss it using a strong magnet, but neither is really practical, particularly for companies that wants to get rid of a dozen of hard drives every year. When you delete a file, or format a partition or drive only a reference links to a names of files and folders are removed, actual data is still sitting intact on a hard drive. In order to clean the actual data from the drive you have to use a drive erasing software (or disk wipe software as sometimes is also referred to). Erasing hard drive works by overwriting sectors with random patterns of binary 0's and 1's. A bits of information can still be preserved after drive erasing but not only it would take a highly specialized and expensive procedure but the random nature of such collected information would make it nearly unusable.
