During the summer I bought a Lenovo R61i notebook with Windows Vista OS (32bit "home premium"). My HDD has got a 160 GB capacity. Recently I realised, that about 40 GB is "missing". If I look in Total Commander and add the used space which is about 95 GB and the free space is 11GB. But the total capacity is about 142GB (because there is an another partition in my winchester which is about 7GB, this is the OSs' part) I checked also the space in the 'MyComputer' and the result is the same than in the TC. Can you please help me how and where can I find that missing 40GB? Thank you.
