Is "Quick Format" safe?
Stoic Joker:
As for data security, a normal non-quick format (which just means zero-filling all sectors - there's really no such thing as a "low-level format" anymore, after a drive leaves the factory) is just fine.-f0dder (November 15, 2010, 02:42 PM)

You sure about that one? For the average end user sure okay, but a business? I've recovered data from a (fully) formatted drive, Even got a good bit (20%) of info off a drive that had been (factory restore) reimaged. Gutmann did mentioned (recommend actually) DBAN in his epilogue.

My MFM drive (on an Amiga 500) would already lose its data when I (lightly) bumped the table it was resting on. The difference between those highly unreliable drives and the rock solidness of the current generations still baffles me.

The RLLs in my A3000 are still reliable, (well after the drive has spun long enough to desolidify the lubricant they are - they sure run hot until that happens :) ).

I don't see how you could restore data from a fully formatted drive - but reimaged is easy, since that only overwrites the partition with what's in the image file, and leaves the rest of the partition untouched.
Stoic Joker:
That's what I thought when I used a WinXP install disk to do a full format on a client machine that was to be wiped. When it finished, I rebooted it expecting to see the typical OS not found message, but it booted back into XP.
Now I'll gladly admit it could have been a fluke, because a statistical sampling of one doesn't prove shit to anyone. But it was an awful spooky fluke...that I've never repeated.
For recovery stuff I've always used Runtimes Get Data Back - That's the best I can remember for details.
