Secure disposal of CD-RWs

Whilst this is a serious request for advice, the potential for frivolous debate and comment is considered so great that I think this is probably the best place to post.
What I would like to know is how people dispose of CD-RW (or any other format) disks containing personal information. I'm interested in terms of both identity theft and environmental issues.
Suggestions using any form of motorised or gas powered kitchen equipment are likely to be vetoed by SWMBO.

Re: Secure disposal of CD-RWs

You can shredders that will shred CD / DVD's. though taking a lighter to them and melting bits or snapping them would make it pretty unreadable.

Re: Secure disposal of CD-RWs

Bang the edge of the disk on a hard surface a number of times. All the bits fall off which renders it unreadable.

An easier solution is to place in n A5 envelope and bend till it breaks. Less hassle and you don't need safety glasses Cool

Thats what I have although it only cuts the disc in 3 places its probably enough to make the data unreadable I would hope. If its really serious data then scratching the top of the CD (where the silver stuff is) with a sharp point before shredding will also do the job.

Re: Secure disposal of CD-RWs

I use a £5 manual shredder that also cuts CD/DVD into 3 pieces.
After shredding a few, I put the 3 pieces into separate plastic bags in bins, and dispose of different weeks, or into different public bins.
Shredder is of this type...


(For paper I use a cross cut shredder, with added water into plastic bag, to smudge ink / make paper soggy)

Re: Secure disposal of CD-RWs

The first step with a CD-RW (or DVD-/+RW) is to fully erase the rewritable disc in a drive. Then after that any of the options above to be completely secure.

Re: Secure disposal of CD-RWs

Personally I never put anything personal from my computer onto rewritable discs, CD or DVD, I reckon they can be un-erased, if re-used.
Stolen or mislaid.
Matters less once shredded of course.
With recordable DVD's costing around 10p each, and not a single failure, I use these as backups.
Plus other means of backup .
And all my personal information is password protected anyway. Excel, Word, PDF's, Photo's Folders etc.
DVD±RW's I only use in my TV DVD Recorders.

Re: Secure disposal of CD-RWs

My fortune !
It's actually very easy, once you get into the habit.
I did try the bendy CD process once, splinters everywhere !
I do wonder if you sellotape the 3 pieces together off the same disc, would it be readable in a tray mounted loader, anyone try it ?
Or what you get with 3 portions of different discs ?

Re: Secure disposal of CD-RWs

You could do what one of my neighbours has done; and attached them to his bicycle wheels so they make pretty patterns of rainbow hues as the wheels turn. Wouldn't think they're much use for anything after a few hours of that.
Experience; is something you gain, just after you needed it most.

When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.
