Description of problem: the hard drive is not turned off gracefully when shutting down the system: a clicky noise can be heard just before the computer turns off. This is an Acer TravelMate 4200 laptop with a Hitachi Travelstar SATA drive. The same problem occurs with fc5 (original kernel and updates) but not with Suse 10.1. The same noise can be heard if the laptop is switched off the hard way with the power button. I had a similar problem with a Dell laptop and other distributions using early 2.6.x kernels (including vanilla). As far as I can remember, it was solved with kernel 2.6.6.

The problem seems to be related to the libata module. Suse applies a libata-acpi-suspend patch which also contains the following part: +/** + * ata_device_shutdown - send Standby Immediate command to drive + * @ap: target ata_port + * @dev: target device on the ata_port + * + * This command makes it safe to power-off a drive. + * Otherwise the heads may be flying at the wrong place + * when the power is removed. + */ +int ata_device_shutdown(struct ata_port *ap, struct ata_device *dev) +{ + + if (!ata_dev_present(dev)) + return 0; + + ata_standby_drive(ap, dev); + ap->flags |= ATA_FLAG_SUSPENDED; + + return 0; +} + However, this was meant for a 2.6.16 kernel.
This problem seems to have been addressed also in Debian (bug #348172). They propose to patch the halt command in sysvinit so that halt -h spins down not only IDE disks but also SATA disks. I tried rebuilding the sysvinit package in fc6 including the Debian patch, and then adding HALTARGS="-d -h" at the end of /etc/init.d/halt, however it doesn't make any difference. Maybe their method of finding SATA disks doesn't work in Fedora, or maybe Fedora unmounts partitions in a different way and the switch -h doesn't do anything.
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Hello, I'm not using Fedora anymore in this computer, so I cannot say whether this bug is still present in more recent versions. I would expect it to have been fixed though. The Suse guys have been working on this issue (http://linux-ata.org/shutdown.html), and recent kernels should spin down disks properly. At least, it works with Suse 10.3.
In that case, I'll close this as INSUFFICIENT_DATA. If you happen to use Fedora on that computer again and note the problem, feel free to re-open this bug report
