Hi,

My Seagate ST1000LM24 hard disk detects in the system when it was kept flat on a surface with label side on top (the side that contains serial number). It doesn't detect when I place it such that the label is on the bottom. Any idea why it is happening? Is it because of loose head?

Thanks,
Ponson
