Re: Things Kids Shouldn't Do at Home
My thanks to all those who theorise that it was this particular
drive's time to die. It is several years old and I was thinking
along the lines that the rest of you were thinking. One thing I
haven't done yet is to see if the clock crystal that drives the
internal usb controller is still active. I am not sure what
frequency it should free run on but one can sometimes hear the
clock on a general-coverage short wave radio receiver or
scanner-type receiver.
What one hears is a signal that usually sounds like a
continuous carrier with no modulation. It's there when the drive
is powered up and goes away when the drive is disconnected.
Thanks.
