Randomly losing gigabytes on my hard drive

Jul 9, 2009 2:09PM PDT

I just bought a Lenovo Y550 with a 400 gb hard drive. It started with around 390 gb which was fine because I know that that missing space is the operating system. But as I was installing programs and downloading stuff I began to randomly lose several gigabytes every now and then on my hard drive. I am down to 330 gb and I can only account for at most 20 gb meaning I'm missing nearly 40 gb. Could someone give me a clue as to what is happening and how to get the space back?

still having issues

Thanks Bob,

I've read both those threads and I still do not know what is going on. I used treesize and I'm missing 40gb give or take. I do not have Thinkvantage Rescue and Recovery as far as i know because my lenovo has lenovo onekey recovery. I tried to find Thinkvantage figuring that it was the most likely source of my lost space, but I either don't have it or can't find where it is. Any help is appreciated.

40GB could be easy to mis calculate.

Here's why. There is about a 7 percent difference from your drive maker's 100GB (they call that 1 billion bytes) to the binary GB (1.07 billion bytes) that Explorer and other programs show.

I see 640 GB drives so 6.4 x 7 is 44.8 so that's all too close to what you listed.

Yes, it may be confusing but each and every time we find no missing space.
Bob
