is there a free app that can write zeros to a laptop with vista, out there?

That is absolutely correct, GB. The cost can easily run into the thousands; the really advanced stuff can be well into the tens of thousands. The state of the art stuff, I have no idea. It needs to be really worthwhile.

Yes, but not, as far as I know, selectively and effectively. You need to erase all and start from scratch.

For the IP reset, open a command prompt, type "ipconfig /renew" and hit enter. I'm not sure what your JAVA issues are; can you expand?

well i had something go whacky and i now can't get onto a board that i know is fine. i spoke to the owners and they say it is not on their side. and said maybe i need to reset my ip. i can't get onto that board using any stand alone browser like chrome, firefox, netscape or avant even AOL explorer doesn't work. i CAN get onto the board through the AOL platform which i hate using except to get my email. i have lost jave options and no java appears in my add/remove but i know it is there. i think there are some components of java missing. i have done a complete reinstall of my OS but it did not cure the problem with java or the website. when vista does a reinstall it places a copy of the old files in my c drive. not a partion. when i open computer in the laft pane it has local disk c and in the list there is listed:
windows
windows.old

i had a program to write my XP to zeros but i don't think it will work for this puter.

any help would be useful.

Formatting a hard disk drive (HDD) does not erase it. I was simply pointing out that if you write zeros over every bit on a HDD, there is absolutely nothing left to recover. Some utilities will write random ones and zeros over every bit and make multiple passes. That's not to be thorough, but to attempt to conceal the fact the wipe every took place.

There are a couple of points on the data recovery issue that I failed to mention. Things like System Restores, temporary files and meta data are often overlooked. The enormous size of HDD's themselves can be a problem. Let's say you have a 250GB HDD that has 199GB of free space and today you delete a 1GB file. Tomorrow you have 200GB free and you add a new 1GB file. What are the chances that the new file will overwrite the old file (which still physical resides on disk)? That file, or significant portions of it, might easily still exist in six months.

OK, I don't want to derail this thread about GBs question and turn it into tech support. I don't mind helping out, though, so why not PM me and I'll see what I can do.

BTW, your zeros program for XP probably didn't do what you thought it did; if the boot sector and whatever is used for file allocation control are not also overwritten, you're in the minor leagues.

I didn't say "format," I said "low level format." Different thing, entirely. A single pass of zeros does not remove the underlying data.

At this point in the thread I want to say that I only jumped in to answer a valid and interesting question from GB. I do this kind of thing for $$$ and DC for my love of cooking. I'm not on the clock, so I'm going to head off to find something interesting to do with the lamb chops on the counter. No offence intended, and if you want some links and/or white papers, let me know.

If you write zeros over every bit on a HDD, there is absolutely never left to recover.

As for your second point, I couldn't agree more. This is supposed to be a holiday weekend. Let's go cook something.
