The burst speed according to Nero DVDspeed is 0.8MB/s, and burning a full DVD at 12x takes about 16 minutes, from what i’ve read it should be more like 7 minutes… I have tried the following:
Changed so it’s on it’s own IDE-channel (master). The current transfer rate is UDMA2 according to System/Hardware in Win XP, BIOS says it’s UDMA2 too.
changing cables, i have 3 different (all new and from different manufacturers).
updated to the latest firmware.
changing various BIOS settings (that shouldt matter in the first place, but tried it anyways, like memory settings etc). Also tried disabling the different automatic settings for the DVD and selecting UDMA2 manualy instead.
I also tried disconnecting the drive and connected an old CD-ROM to the same cable and it’s burst speed was 20MB/s, reading the same (audio)CD on the 1620 gave similar results, 18MB/s. I have no idea if this is too low also, but i think i’d mention it.
Is there anything else i can try that you can think of?
