What is IDE Write Blocker

Handbook of Research on Information Security and Assurance
Most operating systems automatically write some information to a disk when it is connected and the computer is turned on. This hardware device sits between an IDE drive and the computer and does not allow this information to be written to the drive. In forensic investigations, it is crucial to maintain disk image integrity including preventing any data being written from the operating system onto the disk.

Abstract
Hard disk wipes are a crucial component of computing security. However, more often than not, hard drives are not adequately processed before either disposing or reusing them within an environment. When an organization does not follow a standard disk wipe procedure, the opportunity to expose sensitive data occurs. More often than not, most organizations do not wipe drives because of the intense time and resource commitment of a highly-secure seven-pass DOD wipe. However, we posit that our one-pass methodology, verified with a zero checksum, is more than adequate for organizations wishing to protect against the loss of sensitive hard drive data.
