 I made little c program for manually setting idle a disk but now there 
 appears errors in the /usr/include/sys/ata.h !
 
 root at pnserver# cat sleep.c
 #include <sys/ioctl.h>
 #include <stdio.h>
 #include <stdlib.h>
 #include <errno.h>
 #include <fcntl.h>
 #include <sys/ata.h>
 
 int main (int argc, char *argv[]) {
         int fd;
         char *dev = argv[argc-1];
 
         if (argc != 2) {
                 printf("Error with number of args, usage:\n");
                 printf("$ sleep /dev/device_node\n");
                 exit(EXIT_FAILURE);
         }
 
         if ( (fd = open(dev, O_RDONLY)) == -1) {
                 printf("Error while trying to open %s\n", dev);
                 exit(EXIT_FAILURE);
         }
         if ( ioctl (fd, ATA_IDLE_IMMEDIATE, sizeof(ATA_IDLE_IMMEDIATE)) 
 == -1 ) {
                 printf("Error while trying to idle the disk\n");
                 printf("-> ATA_IDLE_IMMEDIATE Code: %d\n", 
 ATA_IDLE_IMMEDIATE);
                 printf("-> Error Code: %s\n", strerror (errno));
                 exit(EXIT_FAILURE);
         }
         else
                 printf("Disk is now idle\n");
         exit(EXIT_SUCCESS);
 }
 root at pnserver# cc sleep.c
 In file included from sleep.c:6:
 /usr/include/sys/ata.h:38: error: syntax error before "u_int16_t"
 /usr/include/sys/ata.h:130: error: syntax error before "u_int16_t"
 /usr/include/sys/ata.h:164: error: syntax error before "u_int16_t"
 /usr/include/sys/ata.h:349: error: syntax error before "u_int8_t"
 /usr/include/sys/ata.h:358: error: syntax error before "caddr_t"
 
 And when I manually set up ATA_IDLE_IMMEDIATE as seen in sys/ata.h:
 #define ATA_IDLE_IMMEDIATE              0xe1
 
 Here is the result:
 root at pnserver# cc sleep.c -o sleep
 root at pnserver# ./sleep /dev/ad1
 Error while trying to idle the disk
 -> ATA_IDLE_IMMEDIATE Code: 225
 -> Error Code: Inappropriate ioctl for device

 So it tells me that 0xe1 is an Inappropriate ioctl for device. I dont 
 understand anything of this !
 ps: When trying with ATA_STANDBY_IMMEDIATE it's the same problem.
 ps2: I cant open the device in O_WRONLY maybe it's there the problem, I 
 don't know well.
 
 Does ata.h and all stuffes related to ata still in development on the 
 6.0-Current ?
 Will ata idle be repaired on 5.4-Release in future (see first post) or 
 must I shift to another distribution (I hope not!!) ?
