Hard drive platters aren't "rusty" at all; they typically have a mirror finish. Perhaps that was a reference to the magnetic coatings on the platters; while not iron, I can sorta see an analogy there. Sanitizing procedures for disks containing TOP SECRET data require one to obliterate the recording medium. For hard disks, that means either sanding down the surfaces of the platters, or melting down the entire platter. Shredding doesn't really enter the picture; it's not required in addition to that, and is not sufficient by itself. For lower levels of classified data, one used to be able to use certified degaussing or software tools. However, these are becoming less and less allowed these days -- both storage and recovery technology has become so sophisticated, and information densities so high, that it is difficult to be sure everything is gone. Physical destruction is becoming the universal requirement. Google for "clearing and sanitization matrix" to see some of the requirements that have been published in the past. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

I have no experience with the internals of a hard drive, but I have done some low-level programming using the external interface of such devices. But it has been a while. I don't recall there being any capabilities to deliver signal information via the external interface. That doesn't mean they don't exist, it just means I didn't come across them in any of the documentation I saw. It would actually makes sense for the hard drive internals to be able to deliver information about what the analog head reads were seeing to the external interface because it would allow the manufacturer/developers, or technicians to do really deep, meaningful diagnostics on a drive. my guess is, that in order to be able to do the types of things you are describing above, you would have to wire some sensors directly into the hard drive electronics. If there are capabilities like the ones you are asking for which can be accessed through the regular external interface, then building an open source tool to access that information would be relatively easy. The most direct path to building such a tool would be to take the existing software drivers for a hard drive and add a few more functions to it that access those particular capabilities.

Eeesh. Yah, I wouldn't try that. If one bit of dust gets between the heads, you could make things a lot worse. A lot safer would be to just swap the PCBs. If it's an electronics failure (as opposed to a mechanical or media problem), that will fix it.

Re: Hard Disk Failure
Depending on the state of the drive, you could try a couple things before sending it off to expensive data recovery centers. For one, you could some sort of data recovery program, which reads data from a drive at a very low level. I've used these with mixed success on drives before. It really depends on the state of the drive. An old trick is to put the drive in a freezer overnight. While I really can't explain it, sometimes you'll get a few minutes of time with the drive when you take it out. And if it doesn't work, you really haven't lost anything. Although, the drive recovery people might wonder why it's so cold :) Another option (one I've never tried and probably is not a good idea) is to buy another of the same model drive and try swapping the platters from the bad drive to the good drive. I believe this is what the drive recovery people do. You have to be really careful, though, because one touch and a finger print is on a platter forever. Not only that but even trace amounts of dust or sand can scratch the hell out of platters when the drive is running. Plus is takes some really small screwdrivers. But, if the data on the drive is not of the most critical importance, it would be a lot cheaper to give this a shot than to spend $1000+ on having someone else do it.
