Drive: This command-line argument specifies the drive letter of the disk for which to display the volume label and serial number. Note: On Windows, the volume serial number is displayed only for disks formatted with MS-DOS version 4.0 or later. OS/2 allows the user to specify more than one drive. The vol command displays the volume labels ...

Serial Storage Architecture (SSA) was a serial transport protocol used to attach disk drives to server computers.It was developed by IBM employee Ian Judd in 1990 to provide data redundancy for critical applications.
The volume serial number is a 32-bit number determined by the date and time on the real-time clock on the current computer at the time of a disk's formatting. Previously, determination by the OS of whether a disk was swapped was done by reading the drive's volume label. However, even at that time the volume label was not required to be unique ...
The first 2 bytes are either hex 10:00 or 2x:xx (where the x's are vendor-specified) followed by the 3-byte OUI and 3 bytes for a vendor-specified serial number. Thus, the difference between NAA 1 format and NAA 2 format is merely the presence of either a zero pad or an extra 3 nibbles of vendor information.
The earliest hard disk drive (HDD) interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data. [a] An additional cable was used for power, initially frequently AC but later usually connected directly to a DC power supply unit. The controller provided significant functions ...
A file with activation key that needs to be installed in same directory as software; similarly, a disc media (often installation disc) may be required as key disk for activation. [1] Code Morphing Hiding intermediate code by means of code obfuscation so that execution logic is not visible. This method does not protect against runtime tracing. [2]
Within the disk drive, this linear block number was translated into a cylinder number, head number and sector number. Moving the translation into the disk drive allowed drive manufacturers to place a different number of blocks on each track transparently to the accessing software. Still later, magnetic hard disks employed an evolution of LBA ...
