数据安全数据销毁

You have a pile of DVDs with sensitive information on them and you need to safely and effectively dispose of them so no data recovery is possible. What’s the most safe and efficient way to get the job done?

问题 (The Question)

SuperUser reader HaLaBi wants to know how he can safely destroy CDs and DVDs with personal data on them:

超级用户阅读器HaLaBi想知道他如何安全销毁带有个人数据的CD和DVD：

I have old CDs/DVDs which have some backups, these backups have some work and personal files. I always had problems when I needed to physically destroy them to make sure no one will reuse them.

我有一些备份的旧CD / DVD，这些备份有一些工作和个人文件。当我需要物理销毁它们以确保没有人会重用它们时，我总是遇到问题。

Breaking them is dangerous, pieces could fly fast and may cause harm. Scratching them badly is what I always do but it takes long time and I managed to read some of the data in the scratched CDs/DVDs.

打破它们是危险的，碎片可能会飞得很快并可能造成伤害。我经常会严重刮擦它们，但这需要很长时间，而且我设法读取了刮擦CD / DVD中的某些数据。

What’s the way to physically destroy a CD/DVD safely?

答案 (The Answer)

SuperUser contributor Journeyman Geek offers a practical solution coupled with a slightly mad-scientist solution:

The proper way is to get yourself a shredder that also handles cds – look online for cd shredders. This is the right option if you end up doing this routinely.

正确的方法是让自己也可以处理CD的碎纸机-在线查找CD碎纸机。如果您最终要这样做，那么这是正确的选择。

I don’t do this very often – For small scale destruction I favour a pair of tin snips – they have enough force to cut through a cd, yet are blunt enough to cause small cracks along the sheer line. Kitchen shears with one serrated side work well too. You want to damage the data layer along with shearing along the plastic, and these work magnificently. Do it in a bag, cause this generates sparkly bits.

我不经常这样做-对于小规模销毁，我倾向于使用一对锡剪-它们有足够的力来切破CD，但过钝却会导致沿纯线的小裂纹。带有锯齿状侧面的厨房剪也能很好地工作。您想要破坏数据层以及沿着塑料的剪切，这些工作效果非常好。放在袋子里做，会引起火花。

There’s also the fun, and probably dangerous way – find yourself an old microwave, and microwave them. I would suggest doing this in a well ventilated area of course, and not using your mother’s good microwave. There’s a lot of videos of this on YouTube – such as this (who’s done this in a kitchen… and using his mom’s microwave). This results in a very much destroyed cd in every respect. If I was an evil hacker mastermind, this is what I’d do. The other options are better for the rest of us.
还有一种有趣且可能很危险的方法-为自己找到一个旧的微波炉，然后将其微波。我会在过程中的通风良好的地方建议这样做，而不是用你母亲的良好的微波。有很多的YouTube上的这个视频-比如这个(谁在做这在厨房...，用他妈妈的微波)。这导致在各个方面都严重破坏了CD。如果我是一个邪恶的黑客策划者，这就是我要做的。其他选择对我们其他人更好。

Another contributor, Keltari, notes that the only safe (and DoD approved) way to dispose of data is total destruction:

另一个贡献者Keltari指出，处置数据的唯一安全方法(且获得DoD批准)是完全销毁：

The answer by Journeyman Geek is good enough for almost everything. But oddly, that common phrase “Good enough for government work” does not apply – depending on which part of the government.

Journeyman Geek的答案几乎可以解决所有问题。但奇怪的是，“足以胜任政府工作”这一常用短语并不适用-取决于政府的哪个部门。

It is technically possible to recover data from shredded/broken/etc CDs and DVDs. If you have a microscope handy, put the disc in it and you can see the pits. The disc can be reassembled and the data can be reconstructed — minus the data that was physically destroyed.

从技术上讲，可以从碎/破碎/等CD和DVD中恢复数据。如果您有便携式显微镜，则将光盘放入其中，即可看到凹坑。可以重新组装光盘，并可以重建数据-减去物理损坏的数据。

So why not just pulverize the disc into dust? Or burn it to a crisp? While technically, that would completely eliminate the data, it leaves no record of the disc having existed. And in some places, like DoD and other secure facilities, the data needs to be destroyed, but the disc needs to exist. If there is a security audit, the disc can be pulled to show it has been destroyed.

那么，为什么不将光盘粉碎成灰尘呢？还是将其烧成酥脆？从技术上讲，这将完全消除数据，但不会留下光盘的记录。在某些地方，例如DoD和其他安全设施，数据需要销毁，但光盘必须存在。如果进行了安全审核，则可以拉出光盘以表明它已被破坏。

So how can a disc exist, yet be destroyed? Well, the most common method is grinding the disc down to destroy the data, yet keep the label surface of the disc intact. Basically, it’s no different than using sandpaper on the writable side, till the data is gone.
那么，光盘如何存在却又被销毁？好吧，最常见的方法是将光盘磨碎以破坏数据，同时保持光盘标签表面完好无损。基本上，这与在可写面上使用砂纸没有什么不同，直到数据消失为止。
