Does anyone know how to completely clear a hard drive?
Absolute security requirements generally specify that the hard drive
has to be physically destroyed in order to prevent any possible
recovery of the data.
There are utilities that will perform multiple overwrites of your hard
drive which provides a high, but not absolute, degree of protection
against data recovery. A 7 pass solution (where the hard drive is
completely rewritten with a random data pattern and then erased 7
times) is the general standard but even then the original data might
still be recoverable if it were important enough to warrant the
expenditure.
For general purposes simply deleting the existing hard drive
partition, then creating a new one and formatting it will provide
acceptable security. Use a Windows 98SE or WindowsMe Startup Disk
(get one from
www.bootdisk.com) and use FDISK to first delete the
existing partition (non-DOS partition if it is NTFS) then create a new
FAT32 partition if that is what you want and format it.
Good luck
