Sold a computer; Is fdisk+format enough?

post #1 of 9
Thread Starter 
I just sold one of my old computers on ebay and would like to make sure that no can pull any data off the hard drives. I have used fdisk to remove all DOS and non-DOS partitions and also created new ones. I then used the format command line to format both drives. When I go back in to install windows XP again I will format once again to the NTFS file system. Is this sufficient? Thanx in advance!

It should quite enough to keep the average person from ever seeing your files. If they were really trying though, they could get back some stuff using a file or hard drive recovery program. The only way to defend against that is to use a program that writes over every part of your hard drive. But that is only necessary if you are concerned that they really want to try to get your stuff.

Reformatting and partitioning rewrites all the file tables but doesn't zero fill. So your files are still physically there on the hard disk, but the operating system thinks the area where your files are is just blank space.

F-disk will only remove partitions. As stated if you wish to 100% erase info then you will need to use a Zero writing program.

Data is still recoverable after a complete disk zero write, if someone wanted to hard enough.

Perform a zero write, one write, and then another zero write to be sure.
Once again...
