Firstly apologies for the delay in getting back!
Well, thanks for the tips I tried them all but to no avail! including updating the USB drivers. I tried my memory stick and even that came up as RAW and 'unable to format'. It did show up as the 'F' drive (as did the ipods) so it wasn't looking to be a 'floppy'. In the end I had to resort to the 'Nuclear' option

So 2 hours later and a shed load of M$ updates and it's all back up and running.
