I'm trying to connect a 3.5" drive to a Pi Zero. However, the drive is not detected by the Pi:

I am using a simple OTG adapter which has worked fine with USB sticks. The drive is connected and powered via a standalone SATA to USB3 adapter (i.e. no hub involved). A photo of the setup follows.

Pi Zero

Any suggestions on what could be wrong with this setup?

The culprit turned out to be the mini OTG adapter: It is cute, but it doesn't work with the hard drive. Switching to a regular OTG cable made the drive appear.

Following is a diff of the boot messages when using the mini OTG adapter and the OTG cable. The message timestamps have been removed to produce a clean diff. Someone more familiar with Pi hardware can perhaps explain what went wrong from this.
