Why Does My Hard Drive Not Show Full Capacity
440 GB, you may be wondering where all those gigabytes went. There are several reasons Windows could display the wrong amount of available space, from invisible shadow files, formatting overhead, and hidden recovery partitions to misleading (though technically accurate) storage

capacities advertised by hard drive manufacturers. Image Credit: Norlando Pobre Why Your Hard Drive Shows Less Space Than Advertised If you’ve paid attention to hard drives, USB flash drives, and other storage devices, you may have noticed that they always have less space than promised once they’re formatted. 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. There's also some overhead required when Windows 500gb hard drive shows only 130 gb of space formats your drive, for the file system and boot data, though in comparison to today's large hard drives, it's not a lot. 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. However, manufacturers of RAM don't sell it in even groups of 1000 – they use groups of 1024. When you're buying memory, a KB is 1024 bytes, a MB is 1024 KB, and a GB is 1024 MB. To work back from the 500,000,000,000 bytes above: 500,000,000,000 / (1024*1024*1024) = 465.66 GB Keep in mind that the hard drive manufacturers are using the accurate description of the terms-the prefix giga, for instance, means a power of 1000, whereas the correct term for powers of 1024 is gibibyte, though it isn't often used. Unfortunately, Windows has always calculated hard drives as powers of 1024 while hard drive manufacturers use powers of 1000. That’s a difference of nearly 35 GB over what the average buyer would be led to believe a hard drive contains. If hard disks were advertised in terms of the amount of space they actually contained when you connected them to your Windows computer, a 1 TB hard drive would be lab

reasons of why your hard drive might lose some megabytes or even gigabytes: Your Operating hard disk size list System does not support LBA48 addressing mode You are mixing binary and decimal gigabytes Your motherboard has created a hidden area external hard drive not showing full capacity on your hard drive to store a backup of the BIOS binaries Your PC/Laptop manufacturer has created a hidden area on your hard drive to store a backup of the Operating System installation files (needed for http://www.howtogeek.com/123268/windows-hard-drive-wrong-capacity/ automatic restore functionality) You have used some software that sets HPA (Host Protected Area), messes with DCO (Device Configuration Overlay), or switches off LBA48 support You have misplaced a jumper on the drive There was Magic involved Now I will go through these things one-by-one and provide some more details. Operating System does not support LBA-48 addressing mode Windows 95, Windows 98 and Windows ME will not support big drives (>137GB) even if http://blog.atola.com/restoring-factory-hard-drive-capacity/ you install all hotfixes. There are ways to get around this problem, but since these Operating Systems are rather rare nowadays, I do not see the point of writing about them. Windows 2000, 2003 and XP do not support big drives by default; you will have to install the latest service pack in order to get big drives working properly on these OS. Windows Vista does not have any issue with big drives. Binary and decimal gigabytes Hard drive manufacturers use decimal gigabytes while operating systems use binary gigabytes. One decimal gigabyte contains 1 000 000 000 bytes (1000 x 1000 x 1000), whereas one binary gigabyte contains 1 073 741 824 bytes (1024 x 1024 x 1024) — that's more than a 7% difference! So, your 300 GB hard drive will show up in Windows as a 279 GB hard drive. Motherboard creates HPA Motherboard can create a so-called "Host protected area" on your hard drive to store its data. Usually this area is not bigger than 10 megabytes, so there is nothing to worry about.
