I've never seen anything like it. Friend of mine bought a brand new external firewire drive from Transintl, one of the clear case/travelstar drive ones.
So we pull it out of the box, attach the included firewire cable and plug into his tower.
It's plugged in for 5-10 seconds, when a red light suddenly comes on in the front of the drive and then a fairly loud pop, the case fills with smoke, and some sort of liquid...and is of course fried beyond beief.
Needless to say it's going back to Transintl. But has anyone seen anything like this before??
