Committed. Now also includes a SMART status check.


grub.cfg example (assumes ata.mod is used):

...
insmod ata_pthru
insmod hdparm

# Make sure disks cannot be locked by an ATA password
hdparm --quiet --security-freeze (ata4)
hdparm --quiet --security-freeze (ata6)

menuentry "Boot" {

 # Check health
 if hdparm --quiet --health (ata4) ; then echo -n ; else
   echo "Warning: SMART status check failed"
   read
 fi

 # Set boot disk to "fast", disable spin down
 hdparm --quiet --aam=254 --standby-timeout=0 (ata4)

 # Set other disk to "quiet", spin down after 5min inactivity
 hdparm --quiet --aam=128 --standby-timeout=60 (ata6)

 # Boot ...
}

menuentry "Memory Test" {

 # Spin down both disks after 10min
 hdparm --quiet --standby-timeout=120 (ata4)
 hdparm --quiet --standby-timeout=120 (ata6)

 # Load memtest ...
}
