DVD+R vs DVD - R

The speed difference might explain my experience that DVD-RWs didn't have errors, it seems it might have been because they are 4X. I was burning the DVD-Rs at whatever speed my burner chose. I've found it best not to use the top-rated speed, but burning 16X at 12X seems to be OK in one of my PCs, whereas burning at 16X sometimes gave errors on the verification pass. David |

The speed difference might explain my experience that DVD-RWs didn't have errors, it seems it might have been because they are 4X. I was burning the DVD-Rs at whatever speed my burner chose. I just let Roxio Easy Media Creator run on full automatic wrt burn speed. As best I can tell, it has always detected the correct speed of the disc I use whether CD or DVD and whether -R or +R. Of course, true burn speed is seldom up to the full speed rating of the disc the same as HDD seldom even approach their rated data transfer rates. As to using HDD for backups, I do that also. I have a Maxtor 280 gig USB external that I use for daily incremental backups if I am doing a lot of image processing or whatever. And, I have a couple of 200 gig externals that I use to back up both my PCs to about every 30-60 days. One of these 2 sits in my bank's safety deposit box and the other in a fire-proof box off the floor in my basement. In the days of early IT, this system used be called "grandfathering" backup tapes, although they used to use 3 sets of tapes. Like you, I find external HDDs to be far faster and easier to use than optical. But, a few times a year, I do create a full set of backup DVDs (used to be a whole lot more CDs!) to add some redundancy to my paranoia about catastrophic loss of data due to a B & E theft, natural disaster, or home fire. As I commented in another post, I don't use RW and haven't had what would look like a speed-related failure in so long I can't recall when. Good luck in whatever you've chosen for your backups et al and have a great week!

This is not what I've been told about the difference in the past. The packs seem to be almost identical, no mention of quality on either pack. -- HP, aka Jerry "Never complain, never explain" - Henry Ford II |

I did just get a 250GB portable HD, and copied my CDs and DVDs onto it. All but one disk read OK, and that one disk read in just one of the three PCs I tried - possibly the one where it was written. Whether it's false security I don't know, but I feel I can trust the HD more (I have two). Cheers, David |

What's the latest thinking on when archived DVDs need to be copied to
fresh disks? After how many years? Thanks Mike Mike On Mon, 11 Feb 2008 10:00:43 GMT, "HEMI-Powered" wrote: MikeM added these comments in the current discussion du jour ...

Have a grea week! -- HP, aka Jerry "Never complain, never explain" - Henry Ford II Jerry, Right now I'm using Taiyo-Yuden DVD+Rs, they have been bullet proof, previously I used HP (made by Taiyo Yuden) But all of a sudden the price dropped and the disks just felt cheap compared to an ealier batch or the other TY disks I have used. I use Plextor, Phillips and Lacie (don't know who makes the DVD drive here) drives. I have heard about using 1X and 2X recording speeds, mostly from archiving sources, but I have also heard of error created when a fast drive is slowed down too much. I let my drives work at their speed, and can't remember the last failed disk I have writen, which of course means I will get one today. The Phillips drive is on a mission critical application backing up a medical photographic system. There is error checking beyond the DVD protocol and again the TY disks have been bullet proof. We do recheck disk integity every year. Over 700 CDs/DVDs in the backup files. Tom |

Thanks Mike It might also depend on what else you're planning to do with your burnt DVDs. Quite a few DVD players that I've recently used can only play back DVD-R discs. It should make zero difference for data to be only read by a computer. |

Rewritable discs (RW) are different technology that has lower reflectivity and higher chance of error on readback as compared to write once (R) discs. I personally would not use them for archival storage. -- Best regards, John Navas Panasonic DMC-FZ8 (and several others) |
