Yoga 2 Hardrive

Hello, I just purchased and received my Yoga 2 and I got the 512gb version.  However, when I looked at the properties, I only have 409 out of 437gb on my C drive and 21 out of 25 in the D drive.  I'm not that tech savvy, but I thought this was quite low and didn't think the operating system took up that much space.  Is this right?  Any feedback is appreciated!

 

Thanks,

Sway

Re: Yoga 2 Hardrive

Hi Sway,

 

Welcome to Lenovo Community Forums!

 

The reason for this difference lies in the way hard drive manufacturers advertise their devices, versus the way Windows computers actually use the storage devices.

 

To a hard disk manufacturer, one KB is 1000 bytes, one MB is 1000 KB, and one GB is 1000 MB. Essentially, if a hard disk is advertised as 500GB, it contains 500 * 1000 * 1000 * 1000 = 500,000,000,000 bytes of space. The hard disk manufacturer thus advertises the disk as a 500 GB hard disk.

Hence,a 500 GB HDD is approximately  500,000,000,000 / (1024*1024*1024) = 465.66 GB

 

Unfortunately, Windows has always calculated hard drives as powers of 1024 while hard drive manufacturers use powers of 1000.

 

Hope this clarified your query!

 

Best regards,

Mithun.
