How to defrag the HDD of the Scientific Atlanta 8000 series.
Push pause for 20 – 25 seconds, until the mail light starts blinking (the little envelop above the clock)
Push the PAGE- (minus) button, you will get E – xx (where xx is a number) instead of the clock.
Push the STOP button 3 times.
Then simply wait. Your machine will defrag and then turn itself off.
You will not lose any data or settings as you would with the reformatting of the drive.
Make sure you DO NOT push the LIST button 3 times instead of the Stop button as LIST will actually reformat the HDD and you will lose all your settings and recordings.
