Memory scrubbing consists of reading from each computer memory location, correcting bit errors (if any) with an error-correcting code , and writing the corrected data back to the same location. [ 1 ] Due to the high integration density of modern computer memory chips , the individual memory cell structures became small enough to be vulnerable ...
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
The Gutmann method, Quick Erase, DoD Short (3 passes), and DOD 5220.22-M (7 passes) are also included as options to handle data remanence. DBAN can be booted from a CD, DVD, USB flash drive or diskless using a Preboot Execution Environment. It is based on Linux and supports PATA (IDE), SCSI and SATA hard drives. DBAN can be configured to ...
Norton Power Eraser (NPE) is a small portable executable which uses Norton Insight in-the-cloud application ratings to scan a computer system. [1] The program matches an application found on the user's computer with a list of trusted and malicious applications. If it's in the list of trusted applications, Power Eraser leaves it on the system.
Eraser securely erases data by overwriting it such that the data is irrecoverable. [1] It supports a variety of data destruction standards, including British HMG IS5 (Infosec Standard 5), American DoD 5220.22-M , and the Gutmann method which features a 35-pass overwrite.
[24] It recommends cryptographic erase as a more general mechanism. According to the University of California, San Diego Center for Magnetic Recording Research's (now its Center for Memory and Recording Research) "Tutorial on Disk Drive Data Sanitization" (p. 8): "Secure erase does a single on-track erasure of the data on the disk drive. The U ...

In magnetic-core memory, each memory cell can retain data indefinitely even with the power turned off, but reading the data from any memory cell erases its contents. As a consequence, the memory controller typically added a refresh cycle after each read cycle in order to create the illusion of a non-destructive read operation.
