xporter thumbdrive capacity question
I've purchased a few months ago (3-4 months) an 8GB usb thumbdrive (XPORTER). I have stored a bunch of files on it - and used only to read those once in a while. Very light usage. I've never paid attention to the amount of available storage on the drive, considering that it must be somewhere close to 8GB. Today I randomly checked how much space I still have available on the drive, and I was surprised to find out that I've used 5.30GB, I have 877MB free, and the total capacity is 6.15GB.
What is supposed to be the total usable capacity of this drive. I know that there is always a difference between the raw, and the formatted capacity, but that can't possibly be 1.85GB!!
Someone please explain.
