Deletion of Files on USB Stick not always Clearing Space

[ian_r_h]

At some point I will need to return to the USB sticks going read-only problem.  This may be more useful generally once I am more familiar with Linux and esp. the terminal.  I only use two brands of USB stick, so that makes it possible to simply control the variables in my case, so it may present an opportunity to investigate the problem for a more general audience too.  Maybe.

Anyway, if I remember, I'll add a link to the dedicated thread at the end of this one, once I am ready to begin...
