POWER
The Maxtor Atlas 10K V hard disk drive operates from two supply voltages:
4.5.1
Power Sequencing
You may apply the power in any order or manner, or open either the power or
power return line with no loss of data or damage to the disk drive. However,
data may be lost in the sector being written at the time of power loss. The drive
can withstand transient voltages of +10% to –10% from nominal while powering
up or down.
4.5.2
Power Reset Limits
When powering up, the drive remains reset (inactive) until both rising Voltage
thresholds reset limits are exceeded for 100 ms. When powering down, the drive
resets immediately when either supply voltage drops below the falling voltage
threshold.
