So, I've got a Vantec Nexstar 3.5" USB 2.0 HDD enclosure. My friend has the Bytecc ME-740U2 3.5" USB 2.0 HDD enclosure. Both have physically similar power bricks, the +12V lead and the +5V lead are both in the same position in the keyed power connection.
He was without his power brick, and he thought that my power brick should work on his enclosure without a problem. So we plugged everything in and flipped the switch. Nothing. The LED on the enclosure was flashing, like it was struggling to stay on. Same applied for the LED on my power brick, it was struggling to stay on. The brick works on my drive and enclosure without a problem.
So we think nothing of it, and just put his drive aside for the time being. But then we started to smell the burnt PCB... and we knew we were in trouble. The controller board on his 120GB Seagate 7200.7 was burnt, and the smell was permeating the air.
The only difference in my power brick is that it is rated to deliver up to 2.0A on the +12V and 2.0A on the +5V. Going off memory, his will output 1.5A on the +12V line. As far as I know, that is irrelevant, because the drive only draws a fraction of that amperage.
Anybody have any ideas? His drive is already dead (lost about 120GB of misc. stuff), but I'd just like to get to the bottom as to why it would fry everything.
