Getting started Data precautions Samsung Electronics shall not be liable for any data loss. Please take care to avoid losing any important data and back up your data to prevent any such data loss. Operating system and software support If you change the product's factory OS (Operating System) to another OS or if you install software which is not supported by the product's original factory OS, you will not receive any technical support, product exchange or refund, and a fee will be charged when requesting a service. Please use your computer with the original factory OS. If you install an OS other than the factory OS, data may be deleted or the computer may not start. * Please use Windows 10 64-bit only for this model. Product capacity representation Storage capacity representation The capacity of the storage device (HDD, 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. Therefore, the available capacity of the HDD in Windows is smaller than the actual capacity due to the difference in capacity calculation. For example, for an 80 GB HDD, Windows calculates the capacity as 74.5 GB, (80x1,000x1,000x1,000) Bytes/(1,024x1,024x1,024) Bytes = 74.505 GB. In addition, the capacity representation in Windows may be even smaller because some programs, such as Samsung Recovery, may reside in a hidden area of the HDD. Memory capacity representation The available memory capacity in Windows is less than the actual capacity of memory. This is because some memory is required for regular system operations. For example, for 1 GB (= 1,024 MB) memory installed, Windows may report the capacity as 1,022 MB or less. 6
