Hi all,

I have an old Seagate Barracuda 7200.12 500GB SATA internal drive that I'm using for backups. Once and awhile, I connect it to my newer computer using an adapter (Bytecc USB 2.0 Drive Mate with power supply (output 12V/2A, 5V/2A)). See attached pic.

A couple weeks ago, after connecting the drive with the adapter, the drive started smoking where the adapter's power supply connects. I immediately disconnected and noticed a lingering burnt rubber smell from the drive.

I tried it one more time a couple days later, and same result. I don't need to connect the USB part of the adapter in order for the smoke to occur.

My question is, is it the drive or the adapter that's causing the problem and why? If it's the adapter, I don't want to use it on another drive and cause that to smoke. If it's the drive, I don't want to buy a new adapter for no reason.

Any help would be much appreciated. thank you!

I'm betting it's the adapter. As to the cause, well that's unclear but if I had to guess I'd say a faulty power plug and/or power transfer issue.

Personally I don't like those and I prefer a docking station.

It's possible that you mixed up the power adapter and put the wrong one in.

Those adapters are poorly regulated. I suspect that an overvoltage killed one of the drive's TVS diodes.
