I bought this computer exactly 4 months ago.  I really thought it was great.  Easy to set up,  worked perfectly..... for only 4 months. Today i started it up and it said hard drive not recognized. Messed with it for several hours and nothing changed.  Just keeps saying hard drive is not installed. I did see that the hard drive was 8 years old, so i guess i shouldn't be surprised. Be very careful when you get a refurbished unit,  it's probably way older than you think. If you do get one, I'd try to choose a seller that gives a one year warranty. My seller was Blair, I wouldn't buy another one from them.
