I think I've noticed similar issues - sometimes Guitar Hero or Rock Band games will have a pause in the beginning, though everything stays synced up pretty well when it starts again. I'm gonna take a guess that you would have to format your HDD to NTFS or FAT before running that utility...right?
Yep, that's a sure sign of the issue--a brief "skipping" at the beginning of a track as the drive spins up when changing songs. No, you don't need to format the drive first, the utility is completely non-destructive. WDIDLE3.exe is a DOS utility. Just hook your drive up via SATA (it won't work over USB-to-SATA) and boot to DOS (a USB flash drive is perfect for this). Run "WDIDLE3.exe /D" which will either set the drive idle timeout to completely disabled or the maximum allowable value, depending on the drive. (For my WD7500BPVT it sets it to 62 minutes, which is effectively disabled.)

anyone know if that problem effects scorpio black 7200rpm 500gb?
Yes, it "affects" that drive and just about all recent WD laptop and desktop drives. Technically, it is a feature (IntelliPark), but in certain applications (Xbox 360, a RAID array, TiVo, etc.) it can cause issues, hence the utility.
There is also a jumper setting for the WD drives which may be optimal when used in the 360. It enables RPS (Reduced Power Spinup) on the drive, which does just what it says--it boots slightly slower in order to draw less power at spinup. I jumpered my WD7500BPVT that way on my JTAG, which seems to have eliminated the 3-4 times out of 100 that the 360 did not boot properly:WD Scoprio Drive Jumper Settings
Since the 360 will always take longer to startup than the drive will, I can't see a reason not to enable RPS.
