A SCSI “device” is any disc drive, scanner, tape backup unit, or other piece of hardware connected to your system using the SCSI bus.
24 ST11950 and ST12550 Installation Guide, Rev. D Refer to the appropriate section below for instructions in terminating a drive. Caution. Installing or removing terminator packs im- properly can result in damage to the termina- tors or surrounding components.

ST11950 and ST12550 Installation Guide, Rev. D 43 Note. Signal ground on the power control board (PCB) and the head and disc assembly (HDA) are con- nected together in this drive and you cannot separate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts.
44 ST11950 and ST12550 Installation Guide, Rev. D Systemgehäuse nicht an die HDA/PCB-Erdung anschließen wollen, müssen Sie das Laufwerk auf nichtleitende Weise (galvanisch isoliert) im Host-System einbauen. Die daraus u.U. resultierende verstärkte elektromagnetische Strahlung fällt in den Zuständigkeitsbereich des Systemdesigners.
ST11950 and ST12550 Installation Guide, Rev. D 45 Formatting the drive Warning. Formatting a drive erases all user data. Be sure that you understand this principle before formatting any hard disc drive. It is not necessary to format a drive which has previously been used to store data, unless your intention is to erase all user data.
