Discrete Tone Penalty; Identification Labels; Safety; Ul And Csa Approval - Hitachi HTS541010G9AT00 - Travelstar 100 GB Hard Drive Specifications

6.10.1 Discrete tone penalty

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 desecrate tone penalty = dLt - 6.0(dBA)
dLt = Tone-to-noise ratio taken in accordance with ISO 7779 at each octave band.

6.11 Identification labels

The following labels are affixed to every drive:
• A label containing the Hitachi logo, the Hitachi Global Storage Technologies part number and the statement
" Made by Hitachi Global Storage Technologies Inc." or Hitachi Global Storage Technologies approved
