Erase Hard Disk and reuse

By grayd ·
What I would like to know is there any known tools/software available for deleting and or(erasing) a windows OS a hard disk and later reformating with another Window OS. Completely resetting all the 1's and O's on the Hard Disk....

best tool I know of for that is the good ol dos fdisk command and then after you are done with that program do a format and you will have a blank drive with a c partition if you chose to make one again. If you so disired you could do the fdisk and not recreate an active partition thus creating a disk that is virtually partitionless. Hope this helps you.

Sorry - answer 1 is incorrect FDisk & formatting will not 'blank' a disk - data written before FDisk & Format is still there and is accessible with some degree of effort - (although MS Windows would probably find some way to do it at the most inconvenient time!)
There are utilities around to do this but Norton Wipedisk is probably the best known.

I agree with poster #2. While Fdisk, and a re-fdisk would probably clear your hard drive to the point where 99.9% of the computer population could not recover it, nothing is impossible.

Norton wipedisk is so effective, especially if you set it to run 10 times, that is write all zeros, all 1's, all 2's etc... that the NSA, CIA, DOD, and the FBI all use it as their approved method of ensuring that a hard drive is certified as "clean".

But unless you have nuclear secrets on your HD, a Fdisk, boot with a Windows disk, format the drive, fdisk again, then load the OS would probably suffice.

To recover anything from this disk after 2 fdisks and a format plus a re-write of the OS would take a major effort costings weeks and hundreds ofthousands of dollars. Even if you cheated on last years taxes, I couldn't see where it would be worth the effort. :)

Posters # 2 and 3 are right.Fdisk and Format only delete the entries in MBR(Master Boot Record) and FAT.The content in the data area will be remain intact.You can use the wipe disk program or if you have disk manager software of your hard disk(if you don't have it then you can download it from ontrack.com or seagate.com) and use it to completely fill the hard disk with zeroes from the maintenance option.You can even format the drive and fill it completely with the contents of some CD's(or the same CD repeatedly) so that all the data area gets
overwritten.repeat this process 4 or 5 times and the data on your hard disk is so jumbled it may be impossible to recover it.
