Rocket Raid 404 RAID 0 array unmounts with heavy disk useage?

[slipperysnowman]

This problem is intermittent. Sometimes during heavy disk useage (usually downloading 200k-800k/s) my system pauses and my RAID 0 array unmounts and the drives spin down. The event log has an error that looks like this:

An error was detected on device \Device\Harddisk1\D during a paging operation.

and then followed by this:

The device, \Device\Harddisk1\D, is not ready for access yet.

and finally,

The system failed to flush data to the transaction log. Corruption may occur.

Fortunately I've never lost any data, my Rocket Raid 404 card's speaker beeps over and over but after reboot the disk is clean and not even a chkdsk is needed. (I boot with the /SOS flag in my boot.ini) The drives are fairly new 8mb cache 350gb WD (under 6 months old). I cannot access S.M.A.R.T. information for the drives because the the highpoint raid card does not support it, even with panterasoft's hdd health or similar. I have seen many posts about utorrents disk caching causing problems, any gurus wanna take a shot at this?

Have you tried forcing the cache size and forcing µTorrent to use the cache even when it doesn't "need" to?

[slipperysnowman]

I have not tried either, what is a good cache size? Also, where can I force utorrent to use the cache?

How fast is your Internet connection (down and up)?

[slipperysnowman]

Internet connection is about 800k down, 45k up. I generally download/upload at about 90% of these numbers.

I turned on overide disk cache; it's set to the default 32MB. Now to look for some "linux isos" to test it... Thanks for the replies.
