Disk spin up problems?

[brtomkin]

I am capturing video from a vcr using AVI_IO. This works great except for one thing. After a certain amount of time the capture will end due to the I/O Buffer being used up. The buffer up to that point will bounce between 0/50 and 1/50, but at the point of termination, the buffer spikes to 50/50. I think I have pinpointed what is happening. It sounds like a hard drive is spinning up, and at the same time, the I/O Buffer spikes to 50/50, resulting in termination of the capture. This has occurred after as few as 9 minutes and as long as 45 minutes. Any suggestions?

My hard disk is 40GB 7200 rpm. It is partitioned with 30 GB as a capture drive and 10 GB as system drive. I have DMA turned on, I have screen saver turned off, and I have my power management settings set to always on. I have another hard drive present in my system, a 40 GB 5400rpm drive, but it is not involved in captures. I have 1.6GHz processor, 384 MB RAM. I am capturing video through a Pinnacle Linx USB cable and audio through SBLive. Thanks in advance for any help.

it may be partitioned but its still the same drive as your swap file and system files which windows like to take a boo at now and then .. make a seperate capture drive ..

sometime drives go through thermal re-calibration and can cause those same things ... but i dont really see that anymore happening ...
