[. . . ] Occasional excursions to drive ambient temperatures of 50°C or 5°C may occur without impact to specified MTBF. To achieve the specified MTBF, the values of Table 7. 4. 1-1 Column 2 must be considered maximum average operating case temperatures. Continual or sustained operation at case temperatures above the values shown in Column 2 may degrade MTBF. Table 7. 4. 1-1. PCB and HDA temperatures Items in Figure 7. 4. 1-1 HDA U2 U8 Q2 Q13 Column 1 Maximum Case Temperatures (°C) Operating (50° Ambient) [3] 60 [2] 80 65 64 67 Column 2 Typical Case Temperatures(°C) at 35°C Ambient [1] 56 72 50 63 61 [1] The temperatures in Column 2 were made in an enclosed box with no air flow at a pressure of one atmosphere. [2] No point on the HDA top cover should exceed the maximum temperature. Measure at a point shown in Figure 7. 4. 1-1. [3] Ambient temperature measured at the side of the drive 0. 25" (6. 4 mm) from the case. Non-Operating -40° to 158°F (-40° to 70°C) package ambient with a maximum gradient of 45°F (25°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with drive. Product Manual - Hawk 1LP Family SCSI-2 (Volume 1), Rev.

Non-Operating -1000 to +40, 000 feet (-305 to +12, 210 metres) 7. 4. 4 Shock and vibration Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonance's may occur internally to the enclosure resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the enclosure to minimize drive movement. The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods shown in Figure 7. 4. 4-1. Orientation of the side nearest the LED may be up or down, though the figure shows it down. Operating The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 10 g's at a maximum duration of 11 ms (half sinewave). Shock may be applied in the X, Y, or Z axis.
