Powered external SATA drive does not spin up, or appear in fdisk

3 1412
I have a 4TB drive formatted as ext4 in a OWC enclosure like this: It has it's own power supply.

It runs and mounts on my Raspberry Pi via USB fine.

I plugged it into my Banana Pro using a eSATA to SATA cable, but can't get it to mount. When I run fdisk -l, lsblk, or even tail -f /var/log/messages it just never appears.

I have unplugged and replugged in both sides of the connection, but still no luck.

I'm running the latest Bananian.

Any ideas?


If it works on Raspberry Pi but with an USB adapter, try if that way also works on Banana Pro.
If that is the case then it should be a problem with the eSata to Sata adapter.

You were right. I ordered another cable and it arrived today. Everything worked without a problem.

Hi Steve,

I have 2 external powered USB drives; the both work with USB connection.

One of my external enclosure have an e-sata connector (Vantec).

I have tried a e-sata to sata cable from Monoprice and it does not work.
