NEVER TURN OFF A HARD DRIVE WITHOUT FIRST
UNMOUNTING IT. YOU MAY LOSE DATA OR DAMAGE
THE DRIVE.
The Importance of Mounting and Unmounting
A hard drive requires two types of connections to "talk"
to a computer: a physical connection, which is made
using the interface cable, and which serves as the line
of communication; and a logical connection, which
allows the two devices to detect and recognize each
other. Establishing the logical connection is called
"mounting. "
Mounting occurs automatically when you turn on a
hard drive that is connected to a computer (assuming
the computer has the necessary drivers). You know that
a hard drive is mounted when you see the drive icon
on the Desktop (Mac) or the drive icon/letter in My
Computer (Windows).
If you want to turn off a hard drive, you first need to
unmount it. If you turn off a drive or disconnect the
interface cable without unmounting it first, the logical
connection will have not been properly terminated. As
a result, you could lose data or even damage the drive.
