[Reding/Wrting hard disk]

Hi All,

I am developing an application to test the hard disk. the idea is to write the some data on all over disk. I need to develop the application in vc++. The one approach is open handles to physical hard disk drives by calling CreateFile() & then using readfile() & writefile(). & other is to use ioctl call & in driver use the function FS_DirectDiskIO. Can anybody tell me which one is better or is there any another better way of doing this?

Thanks!
