Here is my idea...

Was the DVD finalized at the end of the recording process?

No; the disc played up just before I'd filled it.

Can you put it in the original recorder and try to finalize it?

Unfortunately, the original recorder died too.

Or maybe this will help:

I found that with Google, but I haven't read it :-)

I'll give it a look, thanks.

My understanding is that even an unfinalized disk will be seen by recent
Windows versions if put in a dvd burner but not in a dvd reader.

It is a burner it's being read in (or not - still on Track 03; says 1%).

What's still unclear in all of this is ...

It is just the one disk you are having problems with or is it every disk
you try in the drive? I've assumed it's just one specific disk you hope
to retrieve data from.

If it's every disk then go buy a new drive, they're $30.

If it's the disk, keep trying (try multipule drives) till patience runs
out but it's likely you'll not get everything you would like. Regardless
of software used, the drive still receives some "command" to read a
"segment of data", if it can't it can't and different software telling
it to isn't going to change that.

I have had disks (still do in fact) that can be read on some of my
drives but not all of them. I assume every drive has some tolerances and
one drive is at one edge of a limit and another drive is at the other
edge hence problems sometimes arise.

Sorry, it's just one disc. The drive reads other discs.

True; I just find it difficult to believe _all_ of the disc has gone bad
at once. Back when I was recording the disc, I could view (on the
original recorder) all the material I had recorded so far, multiple
times, until it went wrong. (I can't remember now - it was some years
ago! - exactly when things went wrong - i. e. whether I was just
recording another track, or was trying to finalise the disc.)

I have had disks (still do in fact) that can be read on some of my
drives but not all of them. I assume every drive has some tolerances and
one drive is at one edge of a limit and another drive is at the other
edge hence problems sometimes arise.

What would seem likely is that the index information (I don't know how
DVD recorders handle indexing before a disc is finalised) is corrupted;
however, IsoBuster did manage to tell me that the open session contains
15 tracks, and what the LBA and size of those tracks is, so that
suggests it _did_ manage to read that indexing information. It is
however having great difficulty extracting an image of the data - but is
not giving up! It's now still on Track 03, but showing a progress bar
and "2%"; when I went out this morning, it was on 1%. (And the part of
the progress bar that is filled is red most of the time, but
occasionally shows green.) [At this rate, I think it'd take from 1 to
several weeks to complete!]

Looking in the folder where I told IsoBuster to put things, there are
two files so far - DVD+R.ibp, of 280 KB size, and DVD+R.ibq, of size
35,552 KB. (Track 01 is 32,506,856 bytes, and 02 is 2,359,296, so the
ibq file _could_ be tracks 01, 02, plus what it's done so far of 03
[which is 284,983,296].)

I was (obviously) afraid of that.

The reason I asked is that for some reason, it seems (at east in my
experience) that the only place where you can finalize a CD or DVD is in
the drive that created it.

If you add a scratch sagitally, it affects a lot of the error correction
info pertaining to a single record, whereas a radial scratch doesn't do
that.

Replace "sagitally" by "tangentially" in the above.

Sagittal is a synonym of radial :-)

Also, sagitally should have two t's.

I haven't posted in this thread, because I've nothing to contribute.
But coincidentally, I have a library DVD that keeps freezing up in
both players and I couldn't even read it with DVD Shrink. The was no
obvious dirt on it, but someone here had suggested to the OP to wash
it with detergent.

I figured I'd nothing to lose, so I did that and carefully dried it.
Viola! It reads in my computer now. (I haven't tried it in the DVD
player.)

I'm sorry I can't thank by name the person who posted that follow-up,
but if you're reading this you do have my gratitude.

One of the first things I do when a disk causes problems. I've had more
than a few look ok until you got them in just the right light and then
you could make out a smudge or similar.

Remember when cds first came out and the ad that showed a dog with one
in his mouth and then showed it would play? How anyone belives anything
an ad says is beyond me.

I tended to add to discs until they were full, or nearly so, then

Certainly, most of the ones I've had have claimed that that is the case;
I never tried to close one in another recorder. At least one if not all
do let you take an unclosed disc out and return it later so you can do
further things with it (such as close it), so I'm _assuming_ the
information about what's been recorded so far is placed on the disc
somewhere.

I'd assumed there must be large parts of the disc that are _not_
corrupted; however, this doesn't seem to be the case.

DVDRoller has a DVD rescue setting which allows you to tell the drive
that it has a DVD and to rescue on that basis. It will do a rescue on a
disk where the Directory tracks cannot be read, and this is probably the
case with your disk ( Im assuming you have taken care to physically give
the disk a clean etc!). It has a limited free version you can test your
disk with. Give it a whirl! C+

I've had a look at it, and it does look useful - though I don't think
the amount of usage I'd give it justifies the price. However, if the
trial version actually does extract, I may have to stop IsoBuster, as
it's taking for ever!

This may sound utterly stupid, but try it.

It is possible that the only issue you have is a tiny part of your
thumb print on the edge of the disk or some dandruff.
The next thing to try, if the disk still doesn't work in your PC's
internal drive is an *external* drive. For some reason those sometimes
read things internal drives don't like very much.
And if that doesn't work, get back to us.

Thanks, and no it doesn't sound stupid. I may well try it.

Else even the original recorder couldn't play it or finalize it.

It's hard to read a file system without some guidance. One bit well[1]
placed could conceivably kill a disk.

[1] I guess I mean *badly* placed :-)
