Another space confusion query

I have a 4gb SanDisk Cruzer (SDCZ6-4096RB) that I bought several years ago. Its been great but I noticed recently that it says it has only 2.51 gb of free space and 1.22gb in use, but the only files/folders on the disc are system/US3 related (totaling 93.5 mb). I followed the advise given to another forum member to display hidden folders, but when I did that, I found no trash or other extraneous data folders--just a system folder with an Apps folder with 6 folders with alpha-numeric names following an 8-4-4-4-12 character sequence. I've used the drive between 3 computers in the home, all of which use Windows XP. Any ideas as to what to try to regain the missing 1gb of free space?

2.51 + 1.22 = 3.73,  which is .27 less than 4.00, so how do you think you're missing 1GB of space?

 

The number of bytes a device has rarely equals the number of bytes of formated OS space.  Cluster format overhead and FATs use bytes also.

 

A more intriguing question is if 1.22 GB is used and the U3 system folder is 93.5 MB what's allocated in the other 28.5 MB.  LaunchU3 is only 1.27 MB.

Re: Another space confusion query

Let me try to clarify the situation again: 1.2 GB of space on the drive is indicated as "in use" even though the ONLY thing on the disc are systems files/US3 files. Somehow the disc thinks there is 1 GB of something on it even though there isn't. A check of the hidden folders/files showed nothing that can account for the 1GB of missing space. I'm wondering if a system folder dealing with trash may have been deleted somehow. The drive is already formatted FAT32, but would reformatting do anything to recover the lost memory?
