Hi Magnetic,
On page 2-5 of the Mastery Flyer Guide tell you how to short stroke the drives. Also I use the sca <> 50 pin adaptors on Seagate Barracude 18 gb drive with no problem. Just don't push on the top of the adaptors with the power on the circuit board, could short out on the drive case. With the newer harddrives the test should be in the hi 90's. The Barracuda test results 99.8%
1. your drive might be bad.
2. your drive might not be fast enough
