Two most regularly used optical drives recently stopped
recognizing data DVD's that were created on these machines.
There is no issue with CD media. The affected machines
still recognize commercial 'film' DVDs from the public library.
 
When attempting to recognize the media, the OS seems to
completely bog down as explorer attempts to display the
drive contents.
 
Once in a blue moon, explorer succeeds in displaying the
inserted disk, or even a directory on the disk - but
further attempts to access the drive result in explorer
crashing.
 
Nero infotool and CDroller will also sometimes report
presence and type of DVD - succesive running of tests
usually report empty drives.
 
After disassembling and cleaning one drive, it allowed
normal operation for a few minutes, but reverted to
previous state after disk ejection and re-insertion.
 
They are both HT-LG brands, but are located in completely
different PCs (PC-Chips homebrew and Lenovo ThinkCentre
refurb), with different OS (W2K - W7pro)and different
interconnection (IDE and SATA).
 
The Sony, TDK, Philips, Maxell DVD-R media , both blank
and previously written, are recognizable on two other,
less-frequently used machines in the lab, neither having
HT-LG hardware.
 
Replacing the drives with similar types did not correct
the problem.Replacement drives had other issues, which
is why they were hanging around - sticky doors etc, but
included one IDE drive purchased for this repair exercise)
 
All of the LG drives, original and replacements, have labels
dated before 2010. The other PC's that still recognize the
media have similar dates of manufacture, but are Sony or
Matsushita branded.
 
Using the regular suggestions to manipulate the W7 operating
system ( device manager, optical drivers, atapi drivers,
disk management, registry upper/lower limits, sfc etc )
seem to have no effect.
 
I've not reinstalled Nero, and haven't (recently) reverted
to a Windows restore point.'restoring' didn't work the first
time, so I don't expect it to work a second time. That is a
bit of a rabbit hole.
 
I have ordered (by snail delivery) some non-LG drive
replacements as a last resort - but am still curious to
know if this is a more widespread issue.
 
Using DVD media for physical data back-up or transport
doesn't seem to be common these days - but I've had
large USB memory go bad on me lately, too. I also back up
the OS on a USB-connected HDD.
 
I'm discouraged by this experience with DVD media and
hardware, for data.

You need to understand that the recording medium on an R or RW DVD and on a commercially printed DVD are entirely different. The one is a dye that is 'burnt' by the laser, the other is quite literally stamped. Over time, the dye will deteriorate even by playing - which is via the laser at a lower power than when burning - and become less contrasting. At which point it becomes more difficult for the laser to read it. Not true of a stamped DVD. I have always taken the position that a DVD R or RW is a volatile storage medium, not for the ages, as it is chemical in nature.

I would test the DVD player with a "stamped" DVD. If these also fail, I would suspect the optics that may be failing. DVDs will fail to read far sooner than CDs on the same player if the laser is starting to fail.

**Never seen a rusty Landcruiser. My next door neighbour sold his when
it was around 15 years old. It was kept outdoors for it's entire life.
We live on a (saltwater) river. No rust. Japanese cars don't rust (for
the most part). You're thinking of European cars. They rust.
 
That said: I hate Landcruisers. They are nonsensically huge and heavy.
The have no place on city roads.

Aloominum they say. And "nucular" - Dubya in particular made me
shudder when he said that.

**There is no excuse for not pronouncing nuclear correctly, since
Americans do manage to spell the word correctly.

Saying Japanese cars don't rust is equivalent to saying the earth is flat, and Toyotas are by far the worst of the bunch.
 
Google Tacoma frame rot. The entire frame must be replaced.

Sorry, but the British used to call it Alumimum too - the original name
- before deciding to change it to make it consistent with the other metals.
 
Which is more correct?
 
Who cares?

**Typical American crap construction. The Tocoma was not a Japanese
vehicle.
 
Clearly Toyota should have been taking more care with their American
workers.

Eyup. Metals should end in "ium". Like chromium, thorium,
uranium, iron, copper, manganese...
 
Oooops.

I think at least *some* Americanisation of spellings are OK, like
center, meter and *some* substitutions of s with z. Maybe there
are subtle differences in the way they are pronounced that are
lost on us non-native users.
 
However, I find it hard to condone the widespread
mispronunciation of proper names like Iraq as Eye-raq in modern
times. Maybe saying 'Eye-talian' in WWII was understandable, but
not in this age of instant global communication.

OK - let us discuss the "British U" such as in colo u r and so forth. Which has been around for a very long time. But for the purposes of this specious argument, let us agree on 300 years as an arbitrary figure.
a) Each printed U takes up space on paper, ink, space on the printing plate and so forth.
b) That space has an associated cost. Again, being arbitrary, let us agree that each one hundred Us are worth one British penny, then and now.
c) I believe that it would be fair to suggest that at least a billion extra Us were printed per year since 1700.
 
https://www.officialdata.org/us/inflation/1700?amount=1
 
That first year would be £417 in 1700 (240 pence to the pound). Over the last 300 years, the average earned interest rate is about 4.5%.
Just for giggles, let us use that same £417 as a periodic deposit for the same 300 years. That is highly conservative as that £417 would be more like £26,271 today.
 
 
 
Care to guess what those Us cost the British and Brit-speak economies over the last 300 years?

$5,259,278,881.34 And that is only if the first-cost is *as little as * £417 *.
 
And you dare to criticize American spelling?

And now we can add rubbish math! (To which we would always add at least
an "s".)
