Can I Erase/Reformat DVD+R DL RW ?


B

Just installed a new dual layer optical drive. Works as expected
accept one thing. I can't erase/reformat a DVD+R DL RW disc? I've
always been able to do so with a single layer, 4.7 Gb DVD RW disc. I
use Nero 7. Nero will erase/reformat a 4.7Gb DVD+R RW but not a dual
layer.

My guess is the answer is basic. I just don't know it. Please help.

Thanks,

Bob

Are you sure that the dual-layer disc is a re-writeable? If so, then
spread the word...what brand?

Have you tried looking for the answer on the support page of your DVDRW
Vendor?

AFAIK - DL media (Double Layer or Dual Layer) does not come in a re-writable
format.
Which would mean there *is no formatting/erasing possible* of a DL DVD.

I could be incorrect and you have found some media (DL DVDs) someplace that
is re-writable...
Please tell us where and whom is selling it - although my bet is that it is
quite expensive if it exists.

Dual Layer DVD+R DL RW discs cannot be erased.Their format does not permit this at least for now.

The discs have an RW logo on them, so I assumed they are eraseable/
reformattable/re-writeable, just like the 4.7 Gb versions. I bought
two brands of these. Verbatim and Windata at Microcenter.

I feel silly asking this one: why do the discs have an RW logo on
them? That means re-writeable, correct?

Because they can't be erased, does that also mean that any files that
were put on that disc cannot be overwritten with new files if space is
needed?

I don't know of any re-writable Dual Layer discs, at least not at this point
in time... If the disks were to be re-writable, the disc would have to be
labeled "DVD+RW DL". I'm not sure what the RW stands for that you are
referring to, but even my Single layer write-once (DVD+R) discs have that
small "RW" symbol... That symbol does not indicate that the disc is
re-writable... Sorry...

Yes, I noticed the RW logo on the packaging of some DVD+R discs I purchased
a while ago, but I knew they weren't re-writeable, and it made me wonder why
it was there.

I'm not surprised someone was confused/mislead by it.

See how they use the symbols - seems totally contradictory to me.

I can't seem to find any info on exactly what the logo is meant to be
referring to - is it the recorder if not the disc or what?

I'm not about to buy and dual layer media, as it is not good value for
money. I can only think of one ot two applications where it is really
needed.

I think you are refering to the [RW] logo that identifies the DVD + system
as opposed to the DVD - system. There should be something under that logo
that gives the disks as write once only. I am not aware of any DVD RW9
disks in the marketplace at present.

It identified the DVD+RW format of disk. The logo came about because when
the format was first marketed, only re-writeable disks were available.
Market demand forced Philips to introduce write once disks, but the logo was
retained to avoid confusion (except it caused more confusion that it
avoided). Most members of the DVD consortium (particularly Toshiba) will
still not allow DVD+R/RW disks or their drives to display the regular DVD
logo.

The stylized RW is a trademark of DVD+RW Alliance, that'a all.

What brand is right.
I'd love to get one or two dl rw disc 8.5, what I could do with one, the other as backup or spare. Have got dozens of sl rw , CDs 700mg and DVDs 4.7.
As to erasing rws, easy as.
1) Insert rw disk in device,
2) click on all programs,
3) click on computer,
4) right click on BD-RE,
5) from options window select format and left click.
May take a minute or so then rw disk is good to go again.
Works for me, I read instructions and then put in practice by using stuff I could afford to waste.
Have been doing this for the last 10-12 years and still doing it.
All I want is a couple of DVD+/-DL RW 8.5 GB disks.
Just for the record, I still use windows 7 home edition.
