4.9V is certainly within acceptable range of the nominal 5V. However, the < 180mA seems very low for an HDD if it's actually operating. SATA drives I've looked (3.5" and 2.5") have all been higher than 550mA @ 5V right on the hard drive casing label. So maybe when measuring current, you weren't looking at peak usage?
