I bought a 1620 Pro Fw. B7T9 a few weeks ago. Everthing was working fine but as of yesterday I’m having problems with reading DVD disc’s. The drive makes a lot of noise and the speed won’t go over 7x max. Also it starts to read (lots of noise!) slows done again, starts again (etc.). I have tested this on Nero Cd-DVD speed 3.80 (disc quality test) DVDDecrypter (drive makes a lot of noise, tested ASPI and SPTI) and DVDShrink.
It’s not a DMA problem (checked that in the Windows IDE channel settings) and also my CD-Rewriter is on the same IDE channel and reads normal. The burst speed is 19 Mb/s.
All I can think of is PowerDVD asked to set a region a few days ago and I set it to region 2, or a system crash but that shouldn’t normally influence reading speed I think (at least not when DMA is working properly).
I’m really guessing here…mechanical problems?
I’m on a Celeron 900, WinXP SP2, motherboard with VIA chipset.
