https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276303 Bug ID: 276303 Summary: camcontrol stop does not stop a USB-connected SATA drive (regression from 12.4) Product: Base System Version: 14.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: d8zNeCFG@aon.at Scenario: - FreeBSD stable/14 at c87b594732d7 + very few local patches - WD My Book 12TB external drive https://www.westerndigital.com/products/external-drives/wd-my-book-usb-3-0-= hdd?sku=3DWDBBGB0120HBK-NESN - running "camcontrol stop da0 Result: - The drive continues spinning and is immediately responsive to subsequent = read commands. Expected result: - The drive should spin down and enter a lower-power state. - This worked successfully in FreeBSD 12.4. Notes: - In 12.4, after the drive entered the low-power state, there would be a de= lay of several seconds between the time external power to the drive was disconnected and the device being removed from /dev. In stable/14, when disconnecting the external power supply, the device entry is removed immediately. This corroborates the assumption that the drive does not enter= a low-power state at all. - The purpose of executing the "stop" command before removing external powe= r is to ensure that the drive heads are parked and to reduce wear & tear on the drive. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
