Hdaps protect patch

There has been a new release of hdapsd which doesn't use sysfs anymore and therefore reduces timer interrupts. However the version in portage is to be considered outdated. Also, you might need to build the hdaps driver as module. Navigation menu Personal tools Log in. Namespaces Page Discussion. Views Read View source View history.

In userspace there is only one ioctl. In userspace it would be pain to let the driver support all types of devices, scan for them how? If the daemon parks head and blocks ide queue and you kill it, the queue won't ever be unblocked. The whole userspace is paged, so if the daemon locks up disk forever, it would be impossible to turn it off anyway you can with some pain make the daemon unpaged, but you can't do that for user's shell.

They use some auto-adjusting of values. Maybe something like this woule be reliable: get some value how much the notebook moves, if the current value greater that the average over some time , park disk. If you tilt the notebook on a road or move it on the table, it would park which exactly what you want. It is in the process of being moved to the block layer however so that implementation for libata will be simpler.

Pavel Machek. Go to the IBM harddrive firmware update utility page and check if a firmware upgrade is available for your harddisk. Jump to: navigation , search. Using HDAPS in the above state may cause frequent drive spin downs, thereby wearing out your hard disk.
