No, read it again. It doesn't say 50GB. It says (line 1) that you have an 80G disk comprising 155061 cylinders (line 2), each of which are 516096 *bytes* long. btw, lines 2 and 3 are bogus anyway, your drive doesn't look like that, and no drive on the market has looked like that for more than 10 years now. It actually means more something along the lines of "Your disk is 80GB big, and to make your life easier you can consider it to be made up of 155061 cylinders each 0.5M big. Other schemes exist but in actual fact it's really just a long string of 156301488 sectors, numbered sequentially, each one being 512 bytes long" hth alan -- Optimists say the glass is half full, Pessimists say the glass is half empty, Developers say wtf is the glass twice as big as it needs to be?
