The Maxtor Atlas 10K III hard disk drive operates from two supply voltages:



2QYGT 5GSWGPEKPI

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 –100% from nominal while
powering up or down.



2QYGT 4GUGV .KOKVU

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.
