March 8, 201115 yr I have some of these drives that were used in a Raid array and had the WD align programme run on them to correct the 4K MBR situation on XP. I have now added them into my unRaid array (without data of course). Should I have done this straight off, or is there something that I should have done to them first to "unalign" them
March 8, 201115 yr Preclear is nice to do before, but not required. Make sure that the jumper is not on it, and set UnRaid to 4k-aligned on the settings page.
March 10, 201115 yr What does the WD align program do exactly? I thought that it is an alternative to using a jumper to improve performance with XP (or pre-4.7 unRAID). If it does do the same thing as a jumper then setting the drive to 4K unaligned would improve performance.

March 10, 201115 yr I'm guessing here, but I think you want 4K unaligned if the drives have processed by WD align. Treat it like a disk with a jumper. (Don't add a jumper.)
