HDAPS - IBM Active Protection System Linux Driver
This is the Linux driver for the IBM Active Protection System.
Features
- prints accelerometer values
- uses userspace tool to park HD
Project Homepage / Availability
- Project Homepage
- The driver is included in the 2.6-mm series of kernels since August, 26th 2005.
- The driver is now in the mainline (2.6.14).
Status
A driver is included in recent Linux kernels and is actively maintained. However, presently the driver only enables reading of the acceleration data; it does not perform automatic disk head parking. The latter feature is under development. But there are already some useful applications for HDAPS, using the /sys interface it provides. See below.
Applications
Security & Safety
- disk park patch an experimental patch for parking the disk (Linux 2.6.14 for 2.6.15 see below)
- disk park patch adapted for the t41p model kernel 2.6.14 (capability detection disabled, no libsata support)
- disk park patch adapted for the t41p model kernel 2.6.15 (capability detection disabled, no libsata support)
- Updated sata/ide disk protection patches for 2.6.15
- Script for theft alarm using HDAPS
Monitoring
- gkhdaps a GKrellM applet displaying tilt data
- gnome-tilt a gnome applet showing tilt data
