2.7.2 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line. Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 20 MHz. Using 3.3-volt power, the drive is expected to operate with a maximum of 70 mV peak-to-peak square-wave injected noise at up to 20 MHz. Note.
2.7.4 Power-management modes The drive provides programmable power management to provide greater energy efficiency. The drive features the following power-management modes: Table 3: Power-management modes Power modes Heads Spindle Buffer Active (operating) Tracking Rotating Enabled Idle, low power Parked Rotating Disabled Standby/Sleep Parked Stopped Disabled • Active mode The drive is in Active mode during the read/write and seek operations.
2.8 Environmental specifications 2.8.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 70°C (158°F) within the operating ambient conditions. Above 1,000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating Nonoperating 2.8.
2.8.5 Shock All shock measurements in this section are carried out at drive level. For all linear shock test, operating or nonoperating, the input shock level shall be measured at the frame of the disk drive at the specific location indicated by the red ellipse in Figure 6 below for the CF and interface drives. Finger Grip Area S1.2 CF interface drive Figure 6. S1.2 FX interface drive Location where tri-axial accelerometer will be placed on ST1.
2.8.6.1 Operating sweep sine vibration The following lists the maximum operating sweep sine vibration levels that the drive may experience while meeting the performance standards specified. It will consist of a forward and backward sweep from 5 Hz to 500 Hz to 5 Hz. The drive will operate without a hard error while being subjected to the following vibration levels. 5 Hz to 500 Hz @ 2 oct/min 2.8.6.2 1.0 Gs (0 to pk). Maximum displacement may apply below 10 Hz.
2.8.6.4 Nonoperating random vibration The test consists of 15 minutes of random vibration using the power spectral density (PSD) levels specified in the table below. The vibration test level is 3.01 Gs RMS. The drive will not incur any physical damage when subsequently put into operation. Table 5: 2.8.6.5 Nonoperating random vibration profile. Frequency (Hz) G2/Hz 2.5 1.0 x E-03 5 3.0 x E-02 40 1.8 x E-02 500 1.
2.9 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). Discrete tone penalties are added to the A-weighted sound power (LW) with the following formula only when determining compliance: LWt(spec) == LW + 0.1Pt + 0.3 < 4.0 (Bels) where LW = A-weighted sound power level pt == Value of discrete tone penalty [==dLt-6.0 (dBA)] dLt = Tone-to-noise ratio taken in accordance with ISO 7779. All measurements are consistent with ISO document 7779.

Annualized Failure Rate 0.4% AFR at 25°C Load/Unload (LUL) cycles (40°C) 300,000 software-controlled power on/off cycles 20,000 hard power on/off cycles Warranty Per agreement 16 ST1.2 Series Product Manual, Rev.
2.12 Agency certification 2.12.1 Safety certification The drives are recognized in accordance with UL60950-1, CAN/CSA-C22.2 No.60950-1, EN60950 and IEC 60950 as tested by TUV Essen. 2.12.2 Electromagnetic compatibility Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Electromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE).
2.12.4 FCC verification These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually marketed to the customer. As a subassembly, no Federal Communications Commission verification or certification of the device is required.
3.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 3.1 Handling and static discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination. • Store drive in the provided protective casing when not in use. (CF interface) • For the FX interface model drives (ST68022FX, ST66022FX and ST64022FX), turn the power off before installing or removing the drive.
