I just put together a computer from scratch. I'm new at this and not sure if my hard drive is running properly. Everything is installed and seems to be running correctly. The question I have is how do I find out if my hard drive is performing to its capabilities. I have a new MS 6167 mainboard with a Athlon 600. I put a new Western Digital WD136BA-OOAK, Ultra ATA/66, 72,000RPM in the system. I used the Data Lifeguard Tools, Version 2.1, to partition and format the drive. The MS 6167 supports ATA/66. Is there a test to see if I'm getting 66 or is the hard drive doing only 33. How do I know if my DMA is Enable to support 66? With the drive at 72,000, I should see some increase in performance. I always thought and heard that the ATA\66 would show some gain but with the 72,000RPM drive a big difference would be notice. There should be a test that can be performed to see if the hard drive is doing what it is supposed to do. Run at 66. Is there a test that I can do? What about the DMA? How do I check to see if it is properly set?
