First of all, you need to find out the information that since all the requirements for free space on the HDD specified by the developer are too low, we recommend taking into account the number of installed applications, games, collections of music, photos and movies, which also require additional gigabytes. Therefore, the optimal volume for these operating systems will be HDD from 250 GB, and preferably from 500 GB and above. If you are interested not only in the volume of the drive, it is worth considering a few more recommendations. And you can also recover lost data using DATA RECOVERY SERVICES.
