Odd result from Sandra benchmark

[Sarkster]

Im wondering whether any of the forum PC ninjas might have any idea's

im running 2 36gb raptors in a raid0 stripe on an asus p5n-e sli mobo using the onboard nvidia raid.

when benching, it looks good, as you would expect, except for an anomaly at 40% into the drive. ive defraged, run checkdisk and moved the swapfile in case it might be any of those things to no avail.

Any ideas peeps?

Platter change? Would have thought a 36 gig raptor was single platter myself though. Try HD Tach aswell.
