This doesn't sound right. Can you run hdparm -C on the affected devices at the time? What is the result of that? Do the drives spin back up if you use hdparm -z? What is the exact kernel version you are running? Please provide both the package name and exact package version, and the full output from uname -a. Assuming that those drives are connected over USB, do they show up in lsusb output while inaccessible? Is there anything relevant in dmesg output? Are you booting the kernel with any command-line parameters? Please provide the exact contents of /proc/cmdline. A spun-down drive can take a brief time to spin back up (typically on the order of a few seconds), but that SHOULD be handled automatically; clearly something odd is going on in your case if it doesn't. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
