Actually you need to write more than once - multiple passes - to completely write over the information in a magnetic storage unit.

Yes, not sure what the term is, but at a certain point, the cost and effort makes it easier to just try to hack the live system rather than piece together some thrown out, smashed, scrap...

kiwigeek1: remember also they reclaimed all the data of that space shuttle seagate drive after explosion

How much did that cost in man hours though, and where was the drive located. I guess it depends on the importance of retrieving the data. I've seen criminal cases where a relatively minor knock has rendered the data unrecoverable.

Didn't he say the drive is unchanged? That should still be good right? Do a quick format and then a full disk cluster check?

Involuntary autocorrect in operation on mobile device. Apologies in advance.

"It's taken four and a half years, but the data recovery specialists charged with extracting data from a cracked, charred 400MB Seagate drive"
""It was only a couple hundred megabytes of data, which isn't much by today's terms......"

4.5 years to recover bugger all data on a HD with far greater fault tolerance than modern drives . Just who do we really think will be spending MILLIONS
to get some data off our old HD's ??

Time to get real.
Just put a drill through them. Or smash with hammer.

You could always pull the platters out and take them to a trap shooting range.

The old multiple-erase cycles to erase your data fallacy.

Not even an electron gun microscope will reveal your data after a single DD:
