Apparently, 256GB = 233 GB!

My new Sandisk Ultra USB 3.0 thumb drive says 256GB on the back but in Computer Management/Disk Management, it has one 233.25 GB partition that cannot be extended.

The thumb drive’s Properties are as follows:

Used space: 97.0 MB
Free Space: 250,346,389,504 bytes (233 GB)

So a 256GB thumb drive only has 250,346,389,504 bytes which really equals 233 GB…say what???

A common question . . .
