I've tested burning some data onto a DVD+RW and wanted to recover the space. However, it seems that when I use Iomega's Hotburn software to erase (whether full or fast), the old sessions are still kept. When I did a format to packet format however, I got back the entire space. However, erase after format still does not get back the entire space. (I prefer to use normal format as opposed to packet format for greater reliability.)

Is this behaviour normal? CD-RW works fine.

hi!

just got a new multi-format DVD writer, but puzzling over the various DVD formats...

maybe someone can advise? like what's the difference between DVD-R and DVD+R

And how come some DVD media i saw got 9.6GB storage instead of the normal 4.7?

Thanks!

The "Plus" format is backed by microsoft while the "Minus" format is backed by Pioneer. Both formats will probably exist for quite sometime before the manufactuers settled with the more popular one. Although DVD "Plus" standard is newer than "Minus", DVD "Minus" media are more easily available in the market now and there are more choices. Moreover, the prices for "Minus" media are much cheaper so it is more economical to use the "Minus" format if compatibility is not the main concern. The "Plus" format will be useful for those who want to store video and want to playback on standalone DVD players, because the plus format should not have compatibility problem with these players

probably double sided, single layer

for single sided, double layer, should be abt 8GB

also there is double sided, double layer, which is over 15GB

existing consumer DVD writer cannot write on double layer media, but reading shouldn't be a problem

Actually, the "Plus" format is designed and backed up by HP, not microsoft ;), microsoft just join in the "plus" Aillance recently ;), the aillance includes, DELL, HP, MS, Mitsubishi Chemical (Verbatim), Philips, Richo, Sony, Thomson and Yamaha. They claim themselves as the standard everyone is using. The Standard is said to br 90% compatible with DVD-R and 70% compatible with DVD-RW (meaning there is a 30% chance a DVD+RW player might not read cut DVD-RW, but 10% chance of a DVD+RW player unable to read DVD-R disc).

the Minus format is created by Pioneer Electronics, the Original DVD format. basically a big cash cow for them, able to collect a lot of royalties for ever DVD player made ;).

(Ever wondered why a new format was created? :) )

the full space as in 4.7GB?

it's not possible to burn all 4.7GB of the disc.... i can usually burn just 4.5Gb at max out of the whole DVD-RW

Uninstalled and it solved the problem! Thanks, Wai :)

Hi BoXXer, before I uninstalled HotBurn, I was left with only less than 300MB after erasing..... 4.5GB sounds about right :) Thanks, anyway.

hhehe...that is a "features" of +RW actually...background formatting

i suppose u can disabled background formatting somewhere??

i did not install the hotburn software so i am not sure....

but background formatting is suppose to prepare the disc for packet writing, that's why there will be no more free space left

i can squeeze abt 4483MB of data to a disc

DVD+R/RW is from Philips not HP. DVD-R/RW is From Pioneer. DVD-RAM 9.6GB not our market yet. But slowly. Due to NO desktop standalone player can play back. Only IDE DVD-RAM drive Only. The storage space is Big. If you need to backup some good Movie from DVD-9 to DVD-5, used DVD-R/RW. This format is the best for all the playback machine.

I used Germany VOB CD/DVD Instant 6.5 Write software for erase my data on both DVD-R/RW or DVD+R/RW. You can try on Pinnacle CD/DVD instant 7.0

Have been using Nero and burnt about 20GB of data so far.

Is it good to store DVD/CD in an electrical drybox to prolong the life?

9.6GB DVD-RAM is in Singapore. Saw some in SLS. They are in cartridge format. So your DVD-RAM writer must be a cartridge loader not tray loading.

I am using a Pioneer A05 DVD-R/-RW writer, I was also split between getting a - or a +.

But DVD-R/-RW are generally cheaper than +R/+RW, (checked SLS and lots of shops for the price comparison)

And it is more compatitble with DVD players, if I need to copy a DVD movie disc.

Microsoft who has joined the DVD+R/+RW has recently announced support for th -R/-RW in their next OS "Longhorn" in 2005 too.

It seems there are millions of DVD-R users and they cannot ignore them.
