My external USB HDD becomes repeatedly inaccessible after a long time of usage/idleness. The same thing happened before with a very old disk and I thought it was just failing. But I do have the same issue with a new set-up.
I get errors like the following and I have to physically remove the disk from its power supply to get it to work again.
usb 1-1.3: device descriptor read/64, error -71
Device offlined - not ready after error recovery
[sda] Unhandled error code
I'm suspecting some kind of power issue - I heard old RPis do have them. The RPi is plugged into a 2 slot PSU, the HDD is connected with a Y-cable to the same PSU and the RPi. I thought I might get actually less voltage problems when they draw from the same source. I also tried a powered USB hub, but that didn't quite work.
My problem is similar to this Question, but that persons solution is my current state of affairs...
There is also a very old thread on the Ubuntu forums regarding usbcore module options autosuspend and old_scheme_first here I didn't test that yet, because it takes several hours or days for the problem to occur...
Any ideas? Or is it fixed for newer versions of Rpi? Some additional infos:
