BlizzardUK Posted February 20, 2012 Posted February 20, 2012 (edited) I am unsure if it is a coincidence, but about 50% of my Ritek GO5 discs now say "The drive only supports writing these discs at 4x" where-as the other day before I moved a sata controller it was burning every disc at 8x. I had to move a sata controller that the drive runs off from a PCIe x1 slot to a PCIe x16 slot, I heard that x1 can happily go in to such a slot. It shares the same lane as the graphics card but there is more than enough power for a x1 PCIe card as it can go up to x8 PCIe when shared. What is confusing is that some discs work at 8x speed write and others 4x, but they are all GO5 discs. Also my other burner, a USB2 one, records them all at 8x. I am guessing it is too much of a coincidence to not be the sata controller move, but why ? I have moved it to a more powerful socket, not a less powered one. Could it be if both burner and the drive I am copying from is on the same controller ? As I am unsure which HDD is sharing the 2 port sata controller. I also notice I am getting a lot of "Waiting for hard disk activity to reach threshold level" messages when burning on both this drive and my USB2 one at the same time, I usually often do that and never get this message (until now). I guess I can swap leads around so that the sata drive is going to a motherboard sata socket, but I am really curious why ? As I would hate to put a HDD on a port that can't even get 8x DVD writing speeds (and this is what I would have to do as my motherboard is full up with hard drives). I have Windows 7.

LIGHTNING UK! Posted February 20, 2012 Posted February 20, 2012 Media supported write speeds are internal to the drive and its firmware. Moving controllers/slots/channels/ports etc have nothing to do with it. If your drive randomly swaps between saying a G05 disc is supported at just 4x and 4x/8x, it's probably having trouble initialising them properly - due to bad discs or a dirty laser. I don't know how the 'source' drive is connected but the more you have going on with a controller / bus, the slower it'll be working with each individual device/program. You get buffer issues when the hardware can't keep up.
