Secure data erasure on a CD

I don't know how CDs differ from HDs. Can anyone recommend:

1. a good program for securely erasing data on a CD;

2. a good program for scanning a CD which is partially damaged.

3. the name of any other ng where I could ask these questions.

Thanks for any suggestions.

You cannot erase a CD. There are a number of shredders available.

ISOBuster is well known for recovering damaged data on CD's

1. A CD-R cannot be erased. It can be destroyed safely by scratching
radially through the top and the metal layer; spectacularly by briefly
zapping it in a microwave oven. A CD-RW can be reasonably erased with a
full erasure or by formatting for packet writing. Secure erasure (by
writing repeatedly) will shorten its life substantially and is not
recommended.

2. You can try ISOBuster, but potent recovery may require Inspector (not
inexpensive) from http://www.infinadyne.com/

3. Why?

Good question. Thank you both for your replies. Tim

1. You cannot erase CD-R; for CD-RW, do a full erase.
2.

Yeah, it's known as an incinerator. There are also shredders
available which can chop a CD into polycarbonate bits. It's
impossible to erase a CD or CDR once it's been written to. CDRW discs
can be erased on CD-RW drives, you can usually use the program you
wrote the discs with. However, if you're looking for government
military level security in erasing the data, your only sure option is
to physically destroy the discs.

2. a good program for scanning a CD which is partially damaged.

Nero CD-DVD Speed. Assuming your drive can report C1/C2 errors, the
scan-disc mode can report which files are readable and which aren't.
If the read errors are due to a dirty disc, that's an easy fix. If
they're really hosed, there's not much you can do to retrieve them, at
least not without spending a lot of money on retrieval (and even then
there's no guarantee).

You can get it from www.cdspeed2000.com -- owning a version of Nero
isn't a requirement.



3. the name of any other ng where I could ask these questions.

Thanks for any suggestions.

I keep a pair of 10" tin snips in my desk for chopping up old CD's,
credit cards and the like.

Hold them low over the trash can, and cut them into 8 or 10 pieces. If
your really worried, deeply radially scratch up the label side before
cutting, and throw the remains away at different places and times. (I
also mix up shredded documents, and spread them out in in the dumpster
just before they pick it up. Never in a easily removable trash bag where
it's known all the contents go together...)

The snips work great, and also come in handy for cutting heavier stuff
like cardboard, and make easy work out of opening those heavy plastic
packages so many products come in these days. They take up little desk
space too.

I suspect someone out there 'might' still be able to extract some data
off the remains, but it would be one monstrous megabuck ordeal.

In a pinch, busting CD's in the middle of a magazine or newspaper
section works too. Be careful, you can get hurt doing this...

All of these methods are cheaper and easier than a program to do the
same thing. If the OP is hoping to be able somehow to reuse the CDs,
CDRs are cheap as dirt.
