I have built yet another pc for HVS reception and this is my
first experience with Windows 10. I have installed the operating
system on a 250GB SSD which has been automatically labelled C: I have
also installed a large capacity conventional HD for data storage. Now
when I try to initialise this disc I get the message '... could not be
performed because of an I/O device error' . Is this because the SSD
has been assigned 'C' or for some other reason?
