After searching for this a few times before, and trying again (with the search function not working for me) I decided to ask outright.
My question is this: Is there a way to set the write buffer that CD-DVD Speed uses? I believe I have heard of some users incresing this, but I have found no posts (Google or CD Freaks) on if this even truly exists/works. I believe it is a registry tweak, but I only know about the tweak to enable otherwise-blocked MTK drives’ scanning abilities. I believe the default is 20 MB.
The reason I ask is that, even when completely defragmented (using programs like Sysinternal’s Contig), I will often have buffer issues burning an image. I believe my Seagate 320GB 7200.10 has some sort of reincarnation of STIR (Seek To Improve Reliability) (it will do a random seek while idle or while reading/writing, and cause a slight fluctuation in the software write buffer). My 200GB Samsung SP2004C is my system drive and pretty much always has SOME sort of random seeking, and it, too, causes a buffer issue.
Typically, this wouldn’t be an issue for me, but I have recently started using CD-DVD Speed to make sure that the burns don’t fall back in speed due to media quality when I get new batches of media. My HP DVD Writer 1040d (OEM LiteOn DH/LH-20A1H) flashed to LL0A FB/EOS has issues relinking at any point during the burn, from any cause, and I would like to minimize the chance that it will drop to 6x/drop to a lower speed/fail to continue burning–all of which have occurred. The SOHW-1693S that it replaces was also the last of a series that potentially had issues relinking from nanosecond buffer underruns (I personally got NEC-like spikes no matter which firmware I used within the past months burning otherwise good-great YUDEN000 T02, TYG03, MCC 03RG20, and SONY16D1).
