Toshiba 500GB Smooth Running No Detection

[MindMergepk]

Hi,

Need some advice on this Toshiba 500GB 3.5" Drive;

Mode: DT01ACA050
HDKPC05A0A02 S

Drive is spinning fine, no clicking or abnormal sound and no detection in DE as well.
Can anybody guide on this one ? plus it seems it is Hitachi drive ?

thanks in advance

BSY or DRDY?

DRDY
but sound is like busy, can't hear any calibration during spin up.

Last time I had this problem, it was heads.
