I have a HP DVD writer 740i with the HJ24 firmware update. I cannot get my drive to burn discs are the right speed. Everything always burns at 4x though my drive supports up to 16x for burning -Rs. I've checked my IDE cables and I uninstalled and reinstalled my aspi drivers and I've reset my DMA. I got the latest firmware, I even tried flashing to the 840 firmware and the LG GSA-4166B102. The problem remained the same. Every once in a while I would burn something and it would burn at 16x then back to 4x for everything following it. I was playing around with the nero cd-dvd speed 4.60 last night and some how I got it to read up to 16.4x with a quite a bit of speed fluctuations in the graph. I burned a disc at 16x and at 8x. The the 16x one wouldn't work right at all and the 8x had horrible skipping problems. I use i've tried Imation -R, Maxim -R, Memorex +R and HP +R DL. Everyone once in a while I get something that works right but more often then my discs have errors. Can someone give me any information to help me out here?
