Thanks, yeah, I'm about ready to write that one (#1) off.

But I now have at least one other DVD-RW (same type) which looks
zapped. Call it #2. However, #2 has me really puzzled, because it was
definitely OK earlier today (I'd played its contents). I had tried to
erase #1 using Super Blank, and that had failed as I described in my
reply to Mike. So, to learn how a 'good' DVD-RW would be handled, I
ran that in Super Blank too. But *that* failed in exactly the same way
#1 had (after 42 secs versus #1's 54 secs). That has me worried that
Super Blank itself is another problem. A side issue, but certainly
complicating matters. I don't feel like risking another of my DVD-RWs
(I only have 9 in total) so I'd be interested in any comments, or
reports of similar problems with that program please. I cannot now
burn a data file to #2 with Nero Express.

I am now 'running' #2 with Iso Buster. Don't really understand what
I'm doing here you realise (!) but I used its 'Find missing files'
command and FWIW it's showing this:
"Expanding UDF tree (found so far)
Reading all sectors
Sanitising found data"

About 37% through after 20 mins, so it's a slow process. Can anyone
tell me what I'm supposed to do when it finishes please?
