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?

  • Could you post a complete (non-grepped) dmesg log around the moment you plug in the drive? Or is it plugged all the time? In which case, plug it into a running system and collect the log. – Dmitry Grigoryev Jun 11 at 12:10
  • I've tried both. No response in either case for the disk. With the USB stick there were some errors displayed when plugging it in with the pi powered on, and it worked fine if I had it plugged at boot time. I'll add a full dmesg later today. – m000 Jun 12 at 10:02

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.
