*1 Current is typical rms except for spin up.
*2 Power requirements reflect nominal values for +12V and +5V power.
*3 Idle mode is in effect when the drive is not reading, writing, seeking, or executing any
commands. A portion of the R/W circuitry is powered down, the spindle motor is up to
speed and the Drive ready condition exists.
*4 R/W mode is defined as 50% read operations and 50% write operations on a single
physical track.
*5 Seek mode is defined as continuous random seek operations with minimum controller
delay.
