newbie question about dvd-r/cd-r
Hello!
I have a newbie question about dvd-r's and cd-r's. I've noticed some computers are coming out with both a dvd-r and cd-r. Others only have a dvd-r. Is there an advantage of having both a dvd-r and a cd-r? Or is it a redundant feature? One last question, can anyone please explain this: dvd+r/+rw/-r/-rw/cd-rw drive Thank you. al |

Actually if it says only Dvd-r it means it only READS dvd's but will also
read Cd's too. If it says dvd+/- Rw then you cna rewrite dvd's, also you can rewrite cd's. The dvd drive labeled with dvd+r/+rw/-r/-rw/cd-rw, well let me explain there a few differing types of DVD media to write to out there, there are dvd-r, dvd+r, dvd-Ram, dvd+rw, dvd-rw. Not all drives can read all types of media. That drive described can read/write dvd+r/+rw/-r/-rw, also all dvd+/- Rw drives can rewrite both types of cds. |

Is there an advantage of having both a dvd-r and a cd-r? Or is it a redundant feature? It's redundant for the most part--some folks like to use the CD drive for CDs to save wear and tear on the DVD drive--DVD writers, while they are very inexpensive compared to what they used to cost, still cost a bit more than CD writers, and they perceive a cost saving. Also, some CD writers write CDs faster than DVD writers unless that has changed recently. I don't think the read mode of any CD/DVD drive is going kill the drive in under 5 years. Loading your system up with redundant CD/DVD drives does risk spin-up power sags, which can cause bad sectors on your hard drives. |

One extra optical drive aint gunna do that. |

If that happens the problem wasn't an optical drive, it was an inadquate power supply. I'm not so sure HDDs will even suffer bad sectors these days, generally it takes a HUGE voltage sage to be significant, not an amp or two. |

That doesn't mean they died because of excessive usage. The optics get dirty in dirty environments, not because of usage. It is a good theory, but I've opened a few, and many weren't particularly dirty inside, in fact I was surprised at how clean some were. If you're suggesting a laboratory cleanroom, there's an idea, but many drives that fail do not appear to be victims of dirt. I must admit I didnt' do a complete autopsy for a cheap optical drive(s) so the actual cause of death in most cases would be "unknown" but dirt didn't look to be the problem.

It is a major problem. This has been acknowledged in every storage forum. But that's not the same as adding an optical drive, two distinctly different things. Poor power is the cause, not the optical drive, and if adding one reduces the voltage THAT much there was ultimately going to be a problem regardless. I will grant you that if a system was using the entire capacity of the power supply already, it wouldn't be wise to add an optical drive (or anthing else), though it wouldn't be prudent to operate the system like that for any length of time anyway. |
