Thanks for the comments. I will expect to make a decision today.
It may be time to clean the drive, but I'll have to think about using vodka and my wife's bloomers. No Vodka in the house and the nearest package store is 40 miles away. There is a restaurant serving alcohol about 8 miles from town. I suppose I could order a glass of vodka and ask for it to go.

About speed, before retirement, I managed a digitizing project that involved making digital copies of almost 30 years of reels, cassettes, etc. I had others doing the technical part but I did have to purchase the hardware and did a lot of reading about the process. When this started we were among the digitizing pioneers. At that time Plextor burners were considered among the elite and we had a fleet of Plextors which held up under heavy use and produced excellent copies. I am not sure that Plextor has held on to its great reputation. As for recording speed, what was recommended at that time was not to use the fastest speed nor the lowest. I cannot remember what was considered optimum, but it seems like it was 8x or maybe 12x. I still do not use the fastest speeds for music. One of the resources that was very helpful was something called ARSCList, managed by the Association for Recorded Sound Collections.
