Software Update
Why is the capacity representation of the hard disk drive (HDD) in Windows
different from the product specifications?
The capacity of the storage device (HDD or SSD) of the manufacturer is calculated
assuming that 1 KB = 1,000 Bytes. However, the operating system (Windows) calculates
the storage device capacity assuming that 1 KB = 1,024 Bytes, and therefore the capacity
representation of the HDD in Windows is smaller than the actual capacity. The capacity
representation in Windows may be smaller than the actual capacity because some apps
occupy a certain area of the HDD outside of Windows.
For models with the Samsung Recovery app, the HDD capacity representation in
Windows may be smaller than the actual capacity because the Samsung Recovery app
uses a hidden area of 5–20 GB of the HDD to save the recovery image, and that hidden
area is not counted towards the total size available to Windows. The size of the Samsung
Recovery app varies by model.
What is a recovery image?
This refers to the operating system, drivers, and software that are converted to a data
image. It is required to recover the computer and is embedded in the computer's HDD.
However, this is not provided for storage devices where the capacity is less than 64 GB.
How can I restore a computer that does not have the Samsung Recovery app?
Restore the computer with the recovery function provided by Windows. Refer to the
Recover Functionality item in the help for more details.
