Management Component Transport Protocol (MCTP) is a protocol designed by the Distributed Management Task Force (DMTF) to support communications between different intelligent hardware components that make up a platform management subsystem, providing monitoring and control functions inside a managed computer system.
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 ...

Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
Low speed PCI Express (PCIe) interfaces usually for Ethernet and NVMe. ISA bus or LPC bridge. ISA slots are no longer provided on more recent motherboards. The LPC bridge provides a data and control path to the super I/O (the normal attachment for the PS/2 keyboard and mouse, parallel port, serial port, IR port, and floppy controller). SMBus ...
Historically, most SSDs used buses such as SATA, SAS, or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate for SSDs, which ...
Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.
To retain hdparm settings after a software reset, run: sudo hdparm -K 1 /dev/sda Enable read-ahead: sudo hdparm -A 1 /dev/sda Set a volatile HPA of 10000000 sectors on the first hard drive (HPA will be lost after a power cycle): hdparm -N 10000000 /dev/sda
For example, few external drives connected via USB and FireWire correctly send S.M.A.R.T. data over those interfaces. With so many ways to connect a hard drive (SCSI, Fibre Channel, ATA, SATA, SAS, SSA, NVMe and so on), it is difficult to predict whether S.M.A.R.T. reports will function correctly in a given system.
