Data erasure can be deployed over a network to target multiple PCs rather than having to erase each one sequentially. In contrast with DOS -based overwriting programs that may not detect all network hardware, Linux -based data erasure software supports high-end server and storage area network (SAN) environments with hardware support for Serial ...

Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
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.

Erase Fail Count: S.M.A.R.T. parameter indicates a number of flash erase command failures. [51] 177 0xB1: Wear Range Delta: Delta between most-worn and least-worn Flash blocks. It describes how good/bad the wearleveling of the SSD works on a more technical way. 178 0xB2: Used Reserved Block Count "Pre-Fail" attribute used at least in Samsung ...
