Fake USB devices continue to be a problem. These devices claim to have higher storage capacities than they actually have. These devices are sold in many different places: from Chinese online shops to Amazon or eBay…

ValiDrive is a new free tool to test USB drives. It “conducts a data preserving, 576-region spot-check to test the readability, writability, and true storage presence of any drive of any size connected to any Windows’ USB port”…

It turns out that I already had Validrive. I originally downloaded v1.0.1.0 (94.3KB) on 2003-10-24.

Not remembering that, I downloaded it again as a result of this post. It’s still v1.0.1.0… but is now 104KB.

Curiouser and curiouser.

The link at GRC.com indicates it was last updated on Feb 27, 2024 so, regardless of the fact the version # stayed the same, something was changed?

I took a look at the properties for both the old 94.3 Kb and new 104 Kb versions and discovered the difference is the digital signatures.

94.3 Kb signatures:

104 KB signatures:

So the larger size is due to the new sha256 digital signature that was added.
