I want to completely erase/reformat my slave drive. I want to permanently erase all info on my drive with absolutly no traces of past content.

What hardware and or software do I need?

I am using a G4 933 MHZ OSX 1.5GB RAM
The drive I want to erase is a Segate Barracudda ATA IV 75GB

?The only absolutely sure fire way to be 100% positive your data can never be recovered is to use the old kinetic energy utility, a hammer. I'm not trying to be funny. From what I have read this last year an expert can recover long term data storage even from a drive that has been zeroed.

?Is it likely that a drive you have zeroed will be recovered, NO. Is it possible, according to experts, absolutely. The data gets burned in and a program that looks at each data bit and gives it a possible 0 or 1 depending on its magnetic field will recover most data. Most folks don't have access to that kind of stuff. But if the data is really sensitive is it worth the risk?

?Drives are so cheap that is has become easier to assume if it held data you cannot risk, don't let it get back into circulation for who knows what.

?I am being very paranoid, thee are programs that will write zeros and then over write ones and zeroes. That is to any reasonable person a safe secure wipe. Personally I'll just buy a new drive if it held data I can't allow out.

Ask the folks at ProSoft Engineering, the folks that sell Data Rescue. Zeroing, then initializing, erasing all partitions can make it harder. ATTO ETP can erase a drive so there are no partitiion tables.

I see people sell older drives, I remember paying $120 for 15GB IBM (75GXP) couple years ago. Now that would buy a 120GB Special Edition.

Put it in a firewire case or use it for a bookend maybe?

If the Feds are after you you can't hide! They can piece together a destroyed drive, forensic software can recover data even after reformating, and electron microscopes can recover it after being written over many times. I'd say.....melt it. Or scrape the surface of the disks randomly. (try piecing those solutions back together!) http://macgurus.com/infopop/emoticons/icon_biggrin.gif
Tell us what you do, and if you trash it, I want pics!

I remember a product for OS 8/9 that purported to give NSA level secure erases of drives. As I recall it was the equivlant of intialing 7 times and writing zeros each time. No idea if that is even effective...

Did a quick search at www.versiontracker.com (http://www.versiontracker.com) under OS X for Erase, and had several hits. This one is free, and got some good reviews from users: File Vaporizer (http://www.versiontracker.com/dyn/moreinfo/macosx/17619)

Warning: I don't know anymore than this about it, so don't curse my name from the big house why you get caught! http://macgurus.com/infopop/emoticons/icon_biggrin.gif
