I decided not to experiment and bought a disc from the list of supported WD3200BEKT-75PVMT0
with the Wdidle3 I set the parking for 300 seconds, and successfully flashed it according to the instructions from the header. Everything worked great, thank you for the tutorial.
I have a question, any advantages of an increased cache of 16 MB compared to 8 MB original disks, and 7200 rotation against 5400 rpm, which revision of SATA in xbox360 uses? (SATA I/SATA II)
