Same reason that hard drives report that they only hold 74.5Gb when the label on the disk says 80Gb. Rounded down.

Yep. it's all to do with arithmetic and how companies work out the the capacity of a drive. To them, there are 1000 kilobytes in a megabyte. But to be spot on accurate there are actually 1024 kilobytes in a megabyte. Windows uses the accurate figure, hence the difference.

You might also look at the flash drive and notice that it has files and folders on it to tell windows what it is. These will take up a small amout of space that the manufacturer just rounds off.

here are some numbers(boring stuff).

marketing numbers do not equal what PC use.

let's say marketing says 1kb, that means 1000 bytes.
computers consider 1kb = 1024 bytes.
we have a 2.34% difference in the 1kb claims.

let's say marketing says 1mb, that means 1000000 bytes.
computers consider 1mb = 1048576 bytes.
we have a 4.63% difference in the 1mb claims.

let's say marketing says 1gb, that means 1000000000 bytes.
computers consider 1gb = 1073741824 bytes.
we have a 6.86% difference in the 1gdb claims.

so if marketing says 1gb, let's reduce it by 6.86%.
we wind up with 931322575 bytes

therefore your device is ok.

part II - we can use the 931kb number to check the integrity of the product. the consumer must decide. if your 'empty' available space is considerably less(10%?) than 931kb, you may want to return the device.
