In depth
A closer look at Disk Test
Disk Test is a software application that provides users with a simple means of testing any HDD by writing random data or a custom text to the free space, with support for erasing data when done. You are not required to go through the installation process, as this product is portable. This means that, unlike installers, it is not going to update the Windows registry and hard drive with new entries, and it is not going to leave any traces behind after its removal. If you copy the program files to a removable storage device, you make it possible to easily run Disk Test on any computer you have been granted access to, by simply clicking the executable.
