[dba-Tech] USB Memory stick lost space!

Hi John

There is no (noticeable) difference between the gross capacity between FAT32 or NTSF formatting but NTSF formatting initially consumes a little more storage (~30 MB) than FAT32. Any difference is usually caused be the difference in counting method as explained by Stuart.

I don't remember if you can do in on a usb flash drive, but did you maybe change the type of formatting used?  Like the old DOS format to NTFS?

I can see that but it was always reported as 16 before this incident. A Windows Update? ;o)

There's "GB" and there's "GB" depending on who you ask.

Disk manufacturers always use 1000^3 (a gigabyte by definition) when
calculating GB, 

Windows uses 1024^3 (technically a gibibyte). 

Your manufacturer's 16 GB is only equivalent to 15 of Microsoft's


See http://en.wikipedia.org/wiki/Gigabyte for all the gory details.
