A partition is a part of a hard drive and you have the choice to determine the number
of partition on your hard drive. After partitioning a hard drive, there are more
partitions. The computer will regard each partition as a separate disk and each of
them will be showed under "Windows Explorer" (Local Disk C:, Local Disk
D:, Local Disk E: and so on ).
Some partitions are available to operating system
while you can store data in the others partitions. Therefore, after installing a
hard drive in Windows 10, you need to partition it at first, and then format it
before it can be available to Windows 10.
Usually, there is only one partition on hard drive which is made by the computer
manufacturers. However, most Windows 10 users will create more partitions if there
is only one partition or C: drive on hard drive. Why do they need more
As for most of users, there are two essential reasons. One reason is that your
computer can be attacked by virus someday, if this disaster happens on your
partition and you format the partition. What will happen? If there was only one
partition on hard drive that means all of your data will be wiped after formatting.
Nobody wants this exist in his life, so more partitions to store different things or
used to backup are
Another reason is that you can separate your operating system, programs and data. In
this way, it is more convenience for you to manage your different data. What’s more
important is that if one day your system is crashed, you just need to reinstall
system; the programs or data stored in other partitions are still safe.
Besides the two reasons mentioned above, some users partition hard drive due to they
want to have multiple operating systems on the same computer or they worry too many
things in the same partition will drop down the speed of computer. No matter which
reason makes them partition hard drive in Windows 10, there is no doubt that this is
a wise choice for them.
