Shipping OEM drives in styro, peanuts, bubble wrap, clam shells, etc. isn't uncommon for most e-tailers. The potential for damage is minimal as the heads are parked and unable to contact the platter surfaces. Unless there is a severe blow to the drive, they can withstand a lot of abuse in that configuration. Physical damage can occur once the drive is active and the read/write heads are in contact with the disk surface however...so that's when you do NOT want to bounce them around. Congrats to everyone installing their new drives! Keep us up to date should anything unusual happen.
