fq040525-01 - PowerGuard® Instant Erase Activation 
QUESTION: What is the minimum time that the Instant Erase (IE) pins need to be shorted in order to activate the Instant Erase function? ANSWER: Instant Erase is activated immediately after pins 3 and 4 (on the 3-Block LED) are shorted. The erase process will continue even if the pins are no longer shorted. To reset and return the E-Disk® flash drive to Idle mode, user should remove the jumper and wait for the Instant Erase process to finish. The same is true for other modes of PowerGuard®. Instant Erase also has a polling feature that can be enabled or disabled by the user through the E-Disk® Analyzer (EDA) or vendor-specific commands. With polling disabled, the unit will initiate erase immediately after the pins are shorted. With polling enabled, the user can set a poll count (n-value), in 21ms increments for E-Disk® ATA/IDE flash drives. For example, with polling enabled and n = 5, the IE pins would have to be shorted for 105 ms before the erase begins. This feature is used to filter out any glitches that may trigger an unintentional Instant Erase. RELATED LINK(S):  fq040205-10: What are the Different PowerGuardŽ Modes?
