Unable to upload files to Flash drive

Not sure if this helps but here goes.

"I have found that sometimes Windows, definitely XP and maybe other versions, if it has the System Restore feature on, that sometimes the system will take it upon itself to reserve some space for that feature on removable flash drives in addition to the main system drive, even though it's largely useless for those. When it does so, it tends to take up much more space than it should have any right using. Worse, the reserved space tends to be invisible, like free space that has just vanished from the drive, manifesting in such ways as a 480MB flash drive showing no files in Explorer yet having only 200 or so MB free. Even if you choose to unhide both system and hidden files to get a look at the folder, you may not be able to delete the darn things.

In these cases, the way to handle it is to go under the System control panel and turn it off for the affected drives while they are mounted.
