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. Tim |

You cannot erase a CD. There are a number of shredders available.
ISOBuster is well known for recovering damaged data on CD's "Tim Walters" wrote in message ... I don't know how CDs differ from HDs.

Thanks for any suggestions. Tim 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? Mike -- http://www.mrichter.com/ |

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. Tim The forums at www.cdfreaks.com and www.cdrinfo.com may be helpful. --------------------------------------------- Thanks. MCheu |

Thanks for any suggestions. Tim 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... Erik |

Erik 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. Allen |
