Blank DVD not detected

[ed@fcc]

Hi,

Blank DVD's are no longer detected by my system but blank CD's are ok.

DVD's that are already written are ok and will load ok.

Can anyone help

Ed

There are two type DVD disks,
DVD+R and DVD-R ,
If yours is a +R , it must be formatted to be seen by your system.

Sorry, but this is incorrect. I'm sure you meant to say that a DVD/RW must
be formatted. A DVD+/- R does not.

You're an idiot and you're passing bad information.

OK, you got me,
But when I am copying movies, the +R always has to be formatted first.

Hi Guys,

Thanks for your replies but my problem is not just as simple as formatting.

+-RW are always recognised
+R is always recognised

After a little investigation I think that -R depends an the brand.

When I say recognised I mean that the system knows that there is a disc in
the drive. With some brands of -R it says the drive does not have a disc in.
The drive makes a sampling noise and eventually the drive door opens.

No way. I've burned over 150 DVDs+R discs and have not had to format
a single one. Not one.

It could be that the drive is dirty and in need of cleaning if it recognizes
some discs and not others, especially if this is new behaviour. If it's
been happening for a while it may be an issue of good quality discs versus
bad quality discs.

How old is the drive?

Check for a firmware update. These are issued to improve compatibility
with newer disks. If it is old and no longer supported you may need a
new drive or just stick to brands you know work.

If you want to use UDF format (though why you'd do this with a
non-rewriteable disc is questionable) Windows will want to "format" it
regardless of whether it's rewriteable or not. A UDF format disc can be
treated as though it were a giant floppy (or tiny hard drive), the only
difference being that deleting files on a non-rewriteable disc will not
actually reclaim any space.

If you're burning a disc that will play in a DVD player (for example,
movies) then neither type of disc (rewriteable or write-once) requires
formatting. They're either burned in one session and automatically
finalised or they're burned in multiple sessions and will probably require
finalising to guarantee a DVD player will be able to read them. The
difference here is that rewriteable discs can be erased, non-rewriteable
discs can not.

What the original poster was getting at was: when you insert a brand new
blank disc into the drive, Windows detects this and asks you which type of
file system you want to use: ISO or UDF. Windows calls them "Mastered" or
"Live File System" respectively.

Unfortunately, after all that, I don't know the answer to why it's no longer
doing this, unless it's in the Autoplay settings somewhere. I've found +R
discs to be somewhat unreliable in my machine and try to use -R (or -R/W for
UDF) by preference.

Really? Not on my system, but then I have autorun disabled. PLUS I
don't use CDs or DVDs as if they are floppies. I have more hard
drives - internal and external - and more flash drives than a normal
person would need in a lifetime ;-)
