| 499869 | 2006-11-17 04:37:00 | i have a dvd cd and i thought it on dvd 9 format...when i insert it to the drive it says that windows dont detect any cd on the drive and if i open the drive, there are no files present...why? what should i do? | jonkimnicko (10061) | ||
| 499870 | 2006-11-17 14:52:00 | obviously .......try a different disk and see if it reads that one.......I assume you DO have a DVD drive not just a cd ? | drcspy (146) | ||
| 499871 | 2006-11-18 01:04:00 | obviously .......try a different disk and see if it reads that one.......I assume you DO have a DVD drive not just a cd ? or try the dvd in another dvd drive - it's easier to ruin a dvd by a small scratch than a cd, so the dvd might be buggered (or your dvd drive) |

| 499872 | 2006-11-25 04:03:00 | ok...but do cd roms read dvd cds or dvd roms can only read dvd cds? | jonkimnicko (10061) | ||
| 499873 | 2006-11-25 04:29:00 | cd drives can only read cds and connot read dvds dvd drives can read dvds and also cds why? as i understand it: the dvd data is all packed in much denser, and the cd drive cannot reliably read at this higher density (laser too inaccurate i guess). th dvd drive can read dvds and also knows how to read the cds (by adapting to lower density) so dvd looks like this --> 10101110100000101010101110 and cd looks like this --> 1 0 1 0 1 1 1 0 1 0 0 0 0 0 1 0 1 0 1 0 1 0 1 1 1 0 which is how dvds store so much more data on the same size disc dvds also only write data in one location, while cds write data several times incase of a scratch ruining the first copy... the data density and lack of backups is why a dvd will be buggered by only a slight scratch while a cd can sustain pretty major damage i hope that answers your next question:D :nerd: |
