Well that's my question - what is taking up that 6.4 GB space?

NTFS or FAT32 format?  Both take some byte-space for house-keeping.  However, roughly 10% does appear a little bit much.

Are there any directories on it not created by you?  Sometimes, my usb stick will have System Information and Recycle Bin, go figure.

I've just gone to the flash drive's manufacturer/seller website which gives 'explanation' for this - quite interesting but the space used is remarkable - I wonder if it's possible to see what is there on that 6.4GB.

 

Take a look at this:-

Re your suggestions how would I see directories etc.?

Some of my sticks came with backup/restore software, unlocking the stick software, etc. -- all of which I promptly 7zipped, saved to D[data] partition, then formated the stick using normal defaults. No more 5-10% loss.

Oh yes that backup/restore stuff is mentioned in that link info.

 

As a novice I'd be grateful if you would give details on how you '7zipped, saved to D[data] partition, then formatted the stick using normal defaults' I can format OK but the other no!  7zipped the drive etc.?

After installing 7-zip program, opened same, tree-climbed over the usb stick, highlighted the backup/restore directory or directories, clicked plus sign, 7-zip made a zip file of the highlighted stuff.  I copied the zipfile onto my D, data, partition.  Then, making sure I had the usb stick clearly picked out, I right-clicked and chose format.  Within format menu, one can choose quick or unClick quick, simply choose quick.  After that's all done, I began copying from my hard-drive what I wanted on the usb stick.

Most of the difference doesn't exist - this is the same with platter hard drives, and has always been so.

Storage devices quote their capacity in decimal values (GB) whereas the values reported in Windows are binary (GiB). So a 64 GB drive shows as having 59.6 GiB capacity. They are the same number of bytes:

https://www.google.com.au/search?q=convert+64+gb+gib

So the drive starts out with 59.6 GiB capacity (64 GB) and the things mentioned by Verbatim, reserved cells for maintenance if cells fail, storing the firmware, formatting overheads, brings it down to the 57.6 GiB, which is about 61.8 GB
