As mentioned, I can’t get more than 16.6MB/sec (about 10.5x DVD) read or write from my drive. It’s running on a Silicon Image SiI 0680 Ultra 133 controller. It doesn’t matter if it’s just by itself or with another drive. I am using an 80 pin IDE cable. This utility that came with the controller tells me that my Toshiba SD-R5002 is actually in Ultra DMA Mode 2 (33.3MB/sec) and it’s on the controller too along with a 2500A on the same cable. I had a Toshiba SD-M1802 on the same spot on the cable before the 3500A was there, and it was able to go above 10.5x when reading. I am using Windows 98 SE. I think the IDE cable is ok… what else can I try?
Windows 98 suggests quite an old PC, can you provide some system details?
Have you tried the ND-3500A on your m/boards onboard IDE channels?
Checked for BIOS and driver updates for your Silicon Image controller card?
Hi, i’m using the same SI ATA-133 controller card & it won’t work do UMDA mode 2 with TDK 1616N. (same OEM) No problem with other optical drives thr. I suggest you switch to on-board IDE instead.
and one more thing… dma 2 is what the drive would be. dma 2 is 33 meg/sec and your burner is 22 somthing /sec the only way you would be ata 3 (udma 66) is if you had a hard drive or something similar
Ok! I moved the drive to the controller on board, so that the 3500A is Master and this 120GB ATA 100 HDD is a slave. I can get full 16x speed reads now. Thanks.
I don’t know but I think I have the same situation. Nec 3500 goes up to 12.5x read speed and then the speed remains constant.
Nec is single set to primary master on Abit KR7A-Raid (VIA KT266A), 80 pin cable.
W2k, properties are set to Ultra DMA (chosen DMA if available). I have tried to use VIA, M$ and standard IDE ATAPI drivers. Situation is the same.
Has anyone got a solution for the problem?
