Voltage Dips in Flash Drive

[hckeat]

Hi,

I have a question about voltage dips in flash drive, if the voltage of an operating flash drive drops from 5V to 3V or 0V in a short time, eg: miliseconds/microseconds, is there any possibility that the operating flash drive will disconnect or lose data during data transfer with pc?

Thank you.

Assuming that it is a USB flash drive, Is'nt the flash drive getting the 5V from the PC itself? Why do you say that it dips?

This could be a fuzzy problem. I'm not quite sure the data will be lost or not, but any power failure should ideally lead to data loss. The question could be how long the voltage dips.

Ideally the power lines, i.e. +5v must remain fixed unless there is a loose connection somewhere in the pc power lines. However, the -D and +D lines do show level variations down to zero volts, and such momentary fluctuations are normal. Are you sure you measured the power lines or you were monitoring the data lines?
