/sys/block/sda/queue/protect does not exist

[Sandra Dismar]

Hi,
after installing hdapsd and hdapsd-utils (and of course loading the hdapsd-module via `modprobe hdaps'), it's not possible to start the hdaps-Daemon.

The following error-msg ist given:
 * Not starting hdapsd: /sys/block/sda/queue/protect does not exist

dmesg-output:
[ 7711.712000] hdaps: IBM ThinkPad R52 detected.
[ 7711.712000] hdaps: initial latch check good (0x01).
[ 7712.532000] hdaps: device successfully initialized.
[ 7712.532000] input: hdaps as /class/input/input12
[ 7712.532000] hdaps: driver successfully loaded.

/etc/default/hdapsd -DISK is set correctly, I'm using SATA on my system. So, there should be a bug somewhere within the kernel-module or with the hdapsd, I guess.

same problem.

note that the hdaps-utils work correctly. only hdapsd appears to suffer from this issue.

And also hdaps-utils work correctly. Help please;)
