I recently bought Y530 with 4GB RAM 320GB HD with Vista on it. However when I look into explorer or control panel's Computer managemnt utility, I see only 270GB of HD space. I am wondering where did the promised 320GB HD onthis system?
Am I missing anything? I bought lenovo for first time. Can anyone shed somelight on this? Where can I see if the HD really has 320GB?
Thanks for reply

The rule is....
Hard drive manufacturers label 1GB as 1,000,000,000 Bytes.
Operating systems read 1GB as 1,073,741,824 Bytes, or 1024x1024x1024 [1024 to the 3rd power]
Thus a 320GB hard drive would be labeled as 320,000,000,000 Bytes by the hard drive manufacturer. In operating systems, 320,000,000,000 Bytes would be a little over 298GB.
In general, you the specified hard drive size by .93125 and the result is what would be visible and usable to the operating system.
500GB x .93125 = 465.63GB
320GB x .93125 = 298.00GB
250GB x .93125 = 232.81GB
160GB x .93125 = 149.00GB
It's not an exact number, but more or less what it should be. Just remember, you are not being ripped off, it's just the way it is.
