DiskSpeed32 is a program for hard drive speed measurement in Win32 environment.

DiskSpeed32 measures reading speed in whole disk or its part and plots graphical dependence for reading speed by cylinder number. This allows to obtain comparable data not only for different drives, but also for the same disk under different Win32 implementation - Windows 9x/Me or Windows NT4/2000/XP, and also if you change drivers or operation system settings.

DiskSpeed32 allows visually to estimate hard disk surface state and to determinate bad sectors existing, remapped tracks and weakly reading sectors in whole disk, independently of file systems for which disk space allocated and in non allocated space too.
