This *should* be OK, since hdparm fails gracefully in this case. However, sending APM commands to disks that don't support it can have side-effects. I received a report that this was causing bus resets on a Cavium Sabre system with the disk below that would sometimes escalate to a boot failure. [Test Case] Boot a system with a non-USB/non-firewire disk that does not support APM and verify that there are no kernel messages like: SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 04 53 40 fe 21 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 APM_level = not supported [Regression Risk] This change entered Debian and Ubuntu 1 month ago, and no regressions have been reported. One source of regressions might be that configuring APM on a disk that claims not to support it did have some positive side-effect that would no longer occur.
