If I want to erase everything off of a hard drive, and I mean literally wipe it clean 100% nothing on it, is simply going into Computer Management -> Disk Management and deleting the partition sufficient? Or are there still bits and fragments left on the hard drive?

Thanks in advance.
 
When you do that all the data is erase to a point. A recovery program will be able to recover the data.

The only way is to overwrite all the data. This easies way is to use a program to set all binary back to 0's.

I don't know of any but you should search the forum or google.
 
Using a NIST standard DOD wipe (8 passes x2 if I remember correctly; "medium" security) takes about 4 hours on a 60 gig laptop HDD (5400 rpm). A 7200 rpm drive will be faster, but remember it is writing to every single sector multiple times. Just start it and go to bed. Should be done by morning.

Made the mistake once of doing a "high" security wipe on two 20 gig IDE drives at the same time... took about 26 hours. That was bus saturation though.

Boot from linux live cd...then something like...

dd if=/dev/zero of=/dev/sda

DBAN is great too! :p
