It would be useful to have gnome/kde notification when hard drives start
failing. There was some talk in the past about how to implement that
with kobjects. Perhaps you could add for this purpose:
#define KEVENT_BLOCK_CREATE 0x1
#define KEVENT_BLOCK_REMOVE 0x2
#define KEVENT_BLOCK_ERROR 0x4
AFAICT:
The conversation concluded this is the best way to handle ioerrors:
