Try running Defraggler to defragment the drive if it is a mechanical hard drive. Also, how full is the drive?

Hi there Monro,

If the issue persists after defragmenting the drive, you may want to run a brand specific testing tool on the drive. The results will show you whether there is something wrong with it.
In case you use Windows 8, you can disable some services that could lead to a 100% disk usage(superfetch, Windows Search, etc.) Check this thread out: http://www.tomshardware.co.uk/answers/id-2045646/windows-100-disk-usage.html
Also, it may be a good idea to back up the most important data until you resolve the issue.

Hope this will help,
