I do not know how to check drive for errors.
I'm in W10.
I right clicked the D drive (iPod),,,properties...check for errors...opitions were grayed out.
Went to RB dev builds...download stable release...download installer (big button)......windows...dl a zip...
unzip...got to rb utility..says stable release (on dropdown) is 3.13...hit "Install"...progress..not responding..then dl "successfully"
....and then...shazaammmm it's fixed!!
Thanks 1,000,000
