Hey all, just had a system built that is dropping frames on only two drives...specs - P4 2.8 1 gig RAM, Asus P4C800E Mbd. Hard drives are all Western Digital: 74G system, 2 200 G Video capture, one 250 G video Capture. System 74G is the new 10K rpm drive, the others are all SATA 7200rpm w/ 8mb buffers. Problem is, the 200Gig drives drop frames like mad when capturing, the other two are fine (74 and 250.) I looked in the case and mbd manual and saw that the two that are working are hooked up to the SATA connections while the problem drives are hooked up to connections specified as RAID SATA connections. Any advice?
Can you run a check on your HDD read speeds? Try HD Tach. If you have Win XP download the Beta version, if not try ver 2.7. Compare speeds of the drives. If the 200 connected to the RAID SATA shows a significantly lower speed, you may not have DMA access enabled.
To enable you will need to check both your BIOS settings and Windows Settings in the device manager.
