Shorten the lifespan of a drive? Where did you hear that?
What is fragmentation?
The file system that Microsoft Operating Systems use partitions and a formatting that can cause fragmentation of files. In a nutshell new files are added at the end where the old files end. (Like taking a train and each time adding a new part to the train).
However, if you delete files, gaps will be created, then the file system starts to fill in those gaps with new files. (The train misses a part in the middle, fils it with another part again, if it’s full, it adds on the en of the train again).
The end result is that a lot of these files are scattered all over the harddisk; this results in long reading times since the file system has to read several sectors all over the disk. That is fragmentation.
How to deal with it?
By defragging you take this entire file system apart and reallocate the files in a normally ordered fashion, so that reading is optimized. Depending on the degrafmentation program you can even give give extra priority to special files (such as the windows swap file).
If your C: drive is just used for reading in and maintaining the Operating System, you would not need to defrag this disk for the sake of writing dvd’s.
If your D: drive is just used as a temporary storage to make backup of dvd’s, defragmentation is pretty useless. (since those files will all be added on the end, then removed again). However if the dvd would contain a lot of small little files, it may casue slower reading.
I would think that only the drive the data that needed to be burned needs to be defragged before a burn to avoid errors since most the stuff from the C drive is loaded into RAM already. Just want to check with you guys.
Nah, it doesn’t really matter.
btw, I already did make a lot of DVDs by doing this method, and IF only defragging my D: drive is not enough, what is the likelyhood of the DVD+Rs getting errors down the road? I use Taiyo Yuden DVD+R 8x.
Most dvd writers also have a buffer underrun protection to make sure that the files will be written correctly. If the buffer isn’t filled up quickly enough (because the harddisk is still reading those pesky little files), it will wait for the harddisk.
