How can I do a zero level formatting of Hard Disk??

Answer 1

There are many ways. Most drive manufacturers will include a utility (with a ton of warnings) on their website that you can use.

I use KillDisk, which can be downloaded here:

"You can find out the manufacturer of your HD and then attempt to download the formatting tool created by that manufacturer for their HD's. Most HD Mnufactuer have a Zero Fill Low level formatting tool available to erase their HD products. This will clean any existing OS files from your system as well as any viruses other files etc.."

Do you mean to wipe the data on the drive. If so there are a zillion products.

But they leave behind the boot sectors. To get rid of the boot area, you also need to ZAP the drive. It's a free program from IBM.

If you want a totally clean hard drive, first, backup to an external storage device any and all files you want to save.

That's it. Now you have to reinstall everything. Have fun.
