Where has the disk space gone?

[Radio Fixer]

Tried the Paging file set up and this is how the USB G disk looks now.  About the same size free shown 181 GB against the 176 GB of the W7 utility.

   

Had a go with Sreams but there isn't much info on how to drive it and working from Cmd windows goes back 20 years or so for me.  So not helpful.

I know you are against this Nick but say I backed up to another drive and then formatted the USB G: one?  Should fix it I would have thought.  Yes!  it is the hammer approach.

thanks for your interest  Gary
