So, I've gained two used (but in great state) drives DW1620 and DW1640 specially for disc quality scanning. In the working computer both drives scan perfectly and without problems, but in my home computer both of them have same problem - scanning freezes at same place on both drives and on any DVD-disc - at 262 Mbytes with scan speed 16x, at 203 Mbytes with speed 12x, at 135 Mbytes with speed 8x, at 102 Mbytes with speed 6x and at 68 Mbytes with speed 4x. I've tried Nero CD-DVD Speed, Opti Drive Control, DVD Info Pro - same results with all of them.
Transfer rate test and "scandisc" test work perfectly. DVD burning (even DVD+R DL burning!) also works great.
My motherboard is ASUS M3A78-CM, working computer's motherboard is ASUS M2N-SLI (nVidia IDE drivers are installed). I've tried to replace standard Microsoft IDE driver with AMD IDE driver but results are the same. OS on home and working computer is the same - WinXP Pro SP3.
I really don't want to change motherboard on my PC just for disc scanning capability - is there a different solution?
BTW, my LiteOn drives with IDE and SATA interfaces scan PIE/PIF without problems.
Sorry if this problem was discussed before, I've used search and found only this thread with similar problem: http://club.myce.com/f92/benq-dw1650-stops-scanning-nero-cd-dvd-speed-1-2-a-192891/
Thanks in advance for any useful hints.
