    en.wikipedia.org/wiki/Disk_formatting

    A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...

    To determine the actual size and features of a disk, the DEVICE_­CONFIGURATION_­IDENTIFY command is used, and the output of this command can be compared to the output of IDENTIFY_­DEVICE to see if a DCO is present on a given hard drive. Most major tools will remove the DCO in order to fully image a hard drive, using the DEVICE ...

    en.wikipedia.org/wiki/Data_erasure

    Software-based data erasure uses a disk accessible application to write a combination of ones, zeroes and any other alpha numeric character also known as the "mask" onto each hard disk drive sector. The level of security when using software data destruction tools is increased dramatically by pre-testing hard drives for sector abnormalities and ...
