On the 410j, using DSM 3.0-1354, open the Storage Manager and click on the HDD Management tab. A list of the drives in your NAS will appear (one of which should be highlighted). Click on the Cache Management button and a dialog box will appear with some explanatory text and a checkbox reading: "Enable write cache". Click on the checkbox to clear the checkmark. Then, click the OK button on the dialog box to confirm the change.
I only had to do this for one drive to turn off write caching for all four drives in my RAID array. It can't hurt, though, to select each drive in the list and hit the Cache Management button, just to verify that write caching has been turned off on each drive.
Hope this helps...
