I just purchased a Tablo Quad with a 1tb hard drive off Ebay. I was told that it was a Tablo refurbish. Everything worked fine for one day. Today the Tablo would display my live TV channels, but when I try to view, I get the message “Player Error could not complete request(503)”. I played around for hours and couldn’t solve the problem. Finally, I took out the hard drive and then everything worked fine, except for recording. So I put the hard drive back in, thinking that taking the hard drive out and reinstalling, would some how solve the problem. No such luck. Do I need a new hard drive? If so does the Tablo format it when I install a new hard drive? Is there some way to format the existing hard drive? There’s no programs on it. Reformatting may fix the old hard drive.
