Jul 06, Slack space is the leftover storage that exists on a computers hard disk drive when a computer file does not need all the space it has been allocated by the operating system. The examination of slack space is an important aspect of computer forensics. Oct 10, Slack space is another source of unallocated space on a hard drive. Slack space is created when only a portion of space allocated to save information (called a cluster) is used. For instance, say a file size is 25 kb and the computer allocates a 32 kb cluster in which to save the data. The unused portion is slack space.

File slack is an extremely complex technological issue. Fortunately, this article simplifies the concept for even the least technical users to understand.

This space remains empty or left over because each cluster on a disk has a storage threshold and files are random sizes. Therefore, the files only fill a part of the hard drive portion. Imagine you have a bowl and lid. In this example, the bowl is a portion of a computer hard drive. Next drice the bowl is a cup of pudding, in this case it is the file. You pour the pudding into the bowl, it fills the bowl about three-fourths, then you seal it.

The remaining space between the pudding and the lid is the file slack. When a file is saved, the computer puts it into a hard drive cluster on the hard drive bowland it has some leftover space. File slack is a result of computer functionality and there are unintentional benefits of this semi-flaw. The most prevalent benefit occurs in the computer forensics field, as file slack allows users to locate files deleted from sectors. This provides investigators potential clues concerning the data erased by legal suspects on the hard drive.

Computer forensics solves notorious criminal cases by utilizing file slack data to find missing information or clues. One of the most recent, high-profile cases what do daphnia magna eat in the investigation of American Secretary of State Hillary Clinton and deleted emails.

The investigators explained the task of retrieving data was potentially possible because of the extra space in deleted files. This is just one example, as it has been used in many different legal cases involving computers. From basic things like a secret recipe for an award-winning stew, or more complex issues like business data, understanding slack space keeps companies protected.

Furthermore, the idea of slack space helps the average user visualize and understand how data fills up on their computer and hard drive.

Jan 10, File Slack, also called slack space, is the leftover space on a drive where a file is stored. This space remains empty or left over because each cluster on a disk has a storage threshold and files are random sizes. Therefore, the files only fill a part of the hard drive portion. The space between the end of a file and the end of the disk cluster it is stored in. Also called "file slack," it occurs naturally because data rarely fill fixed storage locations exactly, and. Slack space is the leftover storage that exists on a computer's hard disk drive when a computer file does not need all the space it has been allocated by the operating system. The examination of slack space is an important aspect of computer forensics.

Slack space refers to the storage area of a hard drive ranging from the end of a stored file to the end of that file cluster. In typical hard drives, the computer stores files on the drive in clusters of a certain file size. For example, the file system on the hard drive may store data in clusters of four kilobytes. If the computer stores a file that is only two kilobytes in a four kilobyte cluster, there will be two kilobytes of slack space.

Slack space is an important form of evidence in the field of forensic investigation. Often, slack space can contain relevant information about a suspect that a prosecutor can use in a trial. For example, if a user deleted files that filled an entire hard drive cluster, and then saved new files that only filled half of the cluster, the latter half would not necessarily be empty. It may include leftover information from the deleted files. This information could be extracted by forensic investigators using special computer forensic tools.
