Ahard drive that is running slowly may not have been properly.

A hard drive becomes slow when it has not been partitioned properly.

Explanation:

A computer memory consists of the usable memory. This is normally the storage hard-drives that are used to store computer files, programs and any other important self-updating software. For instance, a 1 TB hard drive means that the computer's capacity for storage is ± 1 000 GB.

The disk contains some files needed to run the computer. This is sometimes known as the C-drive.

The other drive is for general storage. This is known as the D-drive.

To generate the two drives, a computer hard drive has to be partitioned. This means that the drive, say, 1 TB has to be divided into two storage systems. Sometimes problems with the partitioning result in the computer not working optimally and being slow.  

depends on what software you are using. google docs or microsoft word or other?
