The Problems

Many users partition their hard disk when installing Windows 10, Windows 8 or Windows 7. However, they may meet the problem that the partitions are not showing up in My Computer or Windows Explore, and many of them do not know why.

There are many reasons for a hard drive partition not showing up:
● You didn’t assign a drive letter for the partition. A partition without drive letter will be hidden so that it does not show up in My Computer.
● Windows 7 or Windows 8/8.1 will keep a system reserved partition if you haven’t partitioned the disk before installing system. The system reserved partition will not show up in My computer.
● If you manually hide some partitions, the hidden partitions will not show up in My Computer, too.
● If you only create a blank disk, which can not be visible in My Computer.
● If the Windows cannot support the file system of the partition, it cannot show up in My Computer.
