HDAPS - IBM Active Protection System Linux Driver

This is the Linux driver for monitoring the acceleratometer known as IBM Active Protection System.

The driver only enables reading of the acceleration data. It does not perform automatic disk head parking. But there are already some other useful applications for HDAPS, using the /sys interface it provides.

Features

  • provides accelerometer values via sysfs

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. The latter feature is under development. See below.

Harddisk Protection

As mentioned above, the hdaps kernel driver is only responsible for reading the accelerometer data and exporting it through the sysfs interface. In order to use this information to protect the disk, some additional steps are required.

See How to protect the harddisk through APS.

Applications

Security & Safety

Monitoring
