external firewire Raid random disconnect problem

Hey all...

Just recently my external Firewire raid drive (plugged into the back of the computer) started "disconnecting" and "connecting" randomly. This happens over and over and I can't for the life of me figure out why. The raid enclosure apparently has no issues as the color lights are indicating it's operating properly.
Power management has been set so that the power to the drives is never shut off.

Has anyone else ever had such an issue?
Thoughts or suggestions on how to get the drive to remain connected?
(by "connected" I do not mean the cables or power supply as I have checked them)

Okay...If this hasn't been posted yet...Here is the fast and easy Fix to Firewire issues (Im on windows 7).

Part 0.5: Make sure your drive is formatted to NTFS. It isnt nessecery, but it really helps in the long run:
1. Navigate to computer.
2. Find your drive
3. Right Click > Format
4. NTFS | Default Allocation | Format

Part 1: Insuring you have proper power settings in effect:

1. Go to Control Panel > Power Options
2. Make sure your computer is plugged in (if your on a laptop).
3. Change Power plan to "High Performance" (If this doesn't show up for you...Try creating a new profile. Desktop users shouldn't have to worry about this.)
4. Okay, click "Change Plan Settings"...Then click where it says "Change Advanced Power Settings".
5. Find Hard Drives > Click the + > Turn Hard Disk Off After > Plugged In > Change this to NEVER.

This will ensure that windows won't just automatically shut off the drive.

Part 2: Making sure your drive Properties are set correctly.

1. Navigate to Computer.
2. Find your Firewire drive > Right Click on the Drive > Properties
3. Select the Hardware tab...and then highlight your firewire drive.
4. Click on Properties.
5. Select the Policies tab.
6. Change the Removal Policy to "Better Performance"
7. Under the Write-caching policy...Enable write caching on this device.

That's it. You should notice increased write and read speeds...and your drive will no longer disconnect.

Cheers,
