I looked in Disk Management and today the listing of B.D. - ROM (M) is not there! Screen shot attached.
I am using Acronis True Image 2014 which I presume is the cause of the listing.
This is the first time it has occurred, so I needed to check that this was nothing to worry about.
I must say, with regards to WIN 7, that since I bought my current pc (made by pcspecialist, UK in 2013), I have not had any memorable problems. Having started with MSDOS and progressing through the sequential Windows systems, this is without doubt the most reliable and dependable O/S. Tried WIN 8 - not as good, WIN 10 - OK if you haven't used WIN 7!
A bit of nostalgia - I bought my first cd only writer in 2000. It was a MIRAI CRD-BP1300P-M and cost just under £200! 12x max write. Now you could buy 10 writers for the same amount. Hey-ho.
Thanks again for your assistance and I have made my donation to the cause of the law suit.
