I have a SATA hdd (adequate power supply) plugged into USB port 3. I have it mounted as an NFS share, using the potato as a server. When I try to transfer a large 4GB video file to a client, dmesg produces the following output:

and, ofc, I’m also unable to transfer the file after a long time
This is an issue with the drive. complt err -2 means the drive did not respond within io_timeout. Either the controller needs a firmware update, the drive has IO errors, or a power issue.
Your first bet is to try disabling UAS. Second try it on another computer to see if you can duplicate the issue.
Smartctl wasn’t showing any issues with it — should I expect to see problems here?
When you mention the controller, what’s a good googling starting point? Western Digital HDD controller firmware?
I don’t have another Linux box, so I’m not sure how I could go about replicating it elsewhere

Looks like no issues…
Do you have the full dmesg log? It looks like the MT7601U could not get a response as well meaning something is hanging on the USB bus since two devices seem to have issues. Also provide a picture of your setup.
How many times have you tried the copy?
first one at around:
[ 2706.416822]
power details from left to right-ish:
4TB WD blue hdd – this SATA adapter – power (to hdd) directly from 12V 5A supply (via 4-way splitter) – 5V step down to power potato – potato
Test this on a PC as this is your most likely culprit.
ty for the pointers – is there a reliable way to go for these kinds of adapters and the USB 2.0 on the potato?
You can use USB 3 ones. It is backwards compatible. Buy the first non-sponsored result should be OK.
