What does designing the 741 and dying at the tender age of 53 have to do
with erasing data off a drive platter?
BTW, google search on "widlarize" returns null.
Thanks,

Google doesn't always work. One story defining the term is in the middle
of this article...

You are correct, nothing! That's surprising.
Nevertheless to "Widlarize" something, is to take a hammer and beat
the thing into little bits. Bob Pease has often written about it.

That's because you didn't click on the "groups" link.
It takes you right to a post defining the term. |

2ea 520MB western digital drives. Standard office environment,

First drive lasted 8 hours. Second drive lasted 4 hours.
I expect that even a simple dust cover would extend this time,
and that a newer, higher capacity drive would crash sooner.

Are those the times before the first sector error?

Those were the times before DOS scandisk running in a looping
bat file stopped with an error.
I am surprised that I haven't seen a bunch of posts from folks who
have tried this. Doesn't everybody has an old 100MB drive or two
laying about?

I'm thinking maybe most of the other sectors were still readable.

Yeah, but I'm not sure of their reliability with the cover on, so it would
be hard to compare. A new drive might last longer. OTOH, a new drive might
be more sensitive. I don't know if I could do a meaningful test.

It depends. If the platter was damaged, yes. If the head was
filled with oxide, it might be all bad reads. If I ever do it again
I will test for that. |

I'd get a warranty replacement drive, and then get a cheap computer
at a thrift store to open up. But that's me.

I had to drill them off.

Torx, schmorx. The first step in doing "physical experiments" on a
hard disk drive is using a Dremel (brand of handheld hobby motorized
tool) with a cutoff wheel to cut head slots in the screws for a
regular flat-blade screwdriver which then easily removes the screws.
It's easy, works great, and it's not like you're going to have to put
it together so that no one knows it's been taken apart.
| Quote: | Now, I need to know a sure fire way of wiping data
off the platters for good. The machine died before I could erase it inside
the computer, so far I have a bunch of 'super magnets' which I dropped
directly onto the platters and let them stay there overnight. Do you think
this is enough? I would like to get them as deleted as I can possibly get
them, but still be able to use the drive as a demonstration device for the
kids. Thanks.
