Hard Drive - Actual Capacity is a free utility tool for Android developed by Mannoun.Net. This program is designed to calculate the actual capacity of a hard disk drive from the advertised one. Have you ever purchased a new hard disk drive with a labeled capacity of 500GB but your computer only showsGB? This program is the solution to that issue.

The program is straightforward to use, and it explains why a hard drive's capacity often appears to be less than the advertised label when showing in Microsoft Windows or Apple Mac. The reason is simple: manufacturers calculate drive capacity slightly differently than how computers actually see usable storage space. Manufacturers count drive capacity using the decimal system, while computers count drive capacity using the binary system, so when you want to convert from one system of measurement to another, there are discrepancies. This program helps you calculate the actual hard disk drive capacity from the advertised one.
