VGN-FZ11S Hard Drive Disk

[ivomarce]

Hello!

This is my first post and first of all I would like to thank everyone in advance for any help and/or share of ideas and tips which will be, for sure, a shortcut for my VAIO's knowledge.

Recently I bought a Sony VAIO VGN-FZ11S which, as we can see on charactetirtics, it should bring a 160GB hard drive disk. Although I noticed on computer info that it only have 137 GB available. This makes me thing about a 140GB HD, not 160GB.

My doubt splits on two questions: on one way my VAIO has a 140GB disk by mistake and I should say it to vendor, or, the 20 GB "lost" which Windows doesn't show, are being used for anything like "Recovery" of VAIO or any other similar protection.

Anyone else faced the same issue?

Once again, thanks everyone in advance.

Greetings,

Ivo

Hi Ivo and welcome.

Everything is OK, you do have a 160GB Drive.

Hard drives are described and advertised by manufacturers in terms of decimal (or base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, and one gigabyte (GB) is equal to 1,000,000,000 bytes. The decimal system is what we are accustomed to in everyday life.

Windows and other programs, such as FDISK, use the binary (or base 2) numbering system. In the binary numbering system, one megabyte is equal to 1,048,576 bytes, and one gigabyte is equal to 1,073,741,824 bytes.

So your 160GB Hard Drive will be read by Windows as 149GB - under both systems it has 160,000,000,000 Bytes capacity.

In addition, you have a hidden Recovery Partition on your HDD containing Recovery Software to reinstall your Vaio - this is about 10GB - so your C:\ drive should show about 139GB.
