Blank Discs

[Tubbycoates]

Hi all,

I've been to the shops to buy some blank discs so I can copy some films I've downloaded to them.

I bought some with a label of CD-R 80, which hold 700mb (or 80 mins).
I've written several of the files to them with no problems.

I also got some discs that have a label of DVD+R, which hold 120 min (or 4.7GB), which I was going to use for longer films than 80 minutes.
However, when I put these discs into my disc drive, the computer doesn't recognise them.

Why?

Thanks in advance.

maybe your drive cannot read dvd's and only cd's, try a retail dvd film and see if it runs, or your drive cannot read DVD+R

did you write them as DVDs or DVD-Data? if you put one in does it show as a drive under "my computer"? Can you see a directory structure? Or does it not read at all?

My drive plays pre-recorded DVD's fine.

The discs just aren't recognised. I just get a message 'Please insert a disc' if I click on the Disc drive

not compatible with your drive, or its a dud disc, try a few more

what app are you using to burn the discs ?

[Postdog]

All drives can read dvd's and cd's. Not all drives can burn them. I've had burnable drives for years but unknowingly bought a pc that didn't, and got exactly that message.

The fact that you've written files to the CD-R discs shows that you've got a drive which can burn discs, rather than just reading them (as many drives are only capable of). However that doesn't mean that it can necessarily handle the DVD+R format. A lot of disc writers can only work with DVD-R discs.

What's the make and model of the drive? (To find out, go to Control Panel and then to Device Manager. Click to expand the entry for DVD/CD-ROM Drives).

As stated by others, it sounds like your drive doesn't recognise DVD+R discs. DVD-R is much more widely used, so try some of those if you can. You could also try a different burning application to make sure - something like ImgBurn, which is free.

Just for clarification, the 80 mins on a CD-R refers to the approximate amount of CD audio, not the length of a film you can fit on it. If your downloaded file is 700 MB then that film could be any length depending on how it's encoded. Similarly a DVD-R is about six times the size of a CD, so you can fit approx 4.3 GB of data on those.

The drive is
HL-DT-ST CDRW/DVD GCCT10N ATA Device

if that is any help !

CDRW/DVD tells us that it is a CD rewriter (CDRW) and a DVD player only (DVD).
A DVD burner would be labelled DVDRW

Ah, so that's why.

Thanks all for your help.
