Well as the title suggests i want to purge, but what you ask? Well when the time comes maybe my 28TBs worth of data. Now i know all about the software side of it with programs that do this (which i also have) including but not limited to: Active@ killdisk, DBAN etc. Now they're good and all but ultimately they're flawed in the sense of time . I bought another 2TB WD 64MB cache HDD a while back and little did i know the HDD was faulty but before acting up it decided to hide it's true state. So i started pouring in data and then i found out it was faulty to which i needed to mail it back to get a replacement. Now i wasn't going to do that with just a format or anything i ran Active@ Killdisk and choose to do a US DoD kill. Now this has 7 passes and i put a custom 95% verification at the end instead of the usual 30%. OMFG this took like 5 days the passes alone only because i left my pc on all day everyday. How long would if of taken if i did another kill method such as gutmann? (this is not where i based my name from) It has 35 passes, that's maybe 5 times longer or even more! Now let me paint you a image. I have some 2TB hdds and also some 1TB (a few WD my passport ones i got for portability) and a few lower capacity ones (old portable ones that i disassembled and mounted to my big hdd only case) all connected to my main pc all the time apart from the portable ones. There i am happily fapping to my pr0nz and then much to my amazement i get v&, i may have a max of 15 seconds before they're in my room. What do i do then? Ask them to come back in a couple of months when all my data has been purged . You may been thinking wow what a loser/ cool dude, with his 28TBs of pr0nz. That's not the main data i store, you can go ahead and think that it is but i don't really care . What i need is some sort of device/ tool that fucks up my hdds real fast and please don't say a mircowave though that does work i don't want to have to unscrew all my hdds and run downstairs to my gaint sized microwave that i don't have to purge my data. I also don't want power tools, i want to keep the hdd looking intact until you try to use it or the purge just f**** data so the hdd is fine and reusable I don't know how a hard drive works fully but i know the basics (platters, a head etc.) but would a magnet work? Maybe only one kind of magnet? Because there are different kinds of magnets out there. Now these are all your standard 3.5" hdds but i wouldn't need a method to do this if they increased usb capacities which is at the moment at 256gb and it costs like $600 . When/ if SDXC supports it's full capacity of 2TB or even if it doesn't 1TB is fine i can have portability, purgability and loads of expandability to play with though i might have to wait a really long time for that to happen (i'll happily pay the money if it does come out expensive) so for now i need a solution to my problem not a day dream into what my come in the future. All and Any suggestions appreciated apart from the ones listed above. Thanks (sorry for the wall of text).
