-------------------------------------------+--------------------------------
 When I install smartmontools, the 'smartd' daemon is automatically
 registered as a StartupItem. After that, it will periodically - every 30
 minutes - query my harddisk:

   Oct 14 00:38:05 Schleppmich smartd[50]: Device:
 IOService:/AppleACPIPlatformExpert/PCI0 at 0/AppleACPIPCI/SATA at B/AppleMCP79AHCI/
   PRT0 at 0/IOAHCIDevice at 0/AppleAHCIDiskDriver/IOAHCIBlockStorageDevice,
 failed to read SMART Attribute Data

 during which my computer ''freezes'' completely for about five to ten
 seconds.
 Removing smartmontools and killing smartd also stopped the repeated
 freeze.

 Issue:
 Querying SMART attributes should not freeze the computer (I am running
 several Linux machines where smartmontools work fine without freeze).

 Hardware:
 {{{

 Also, 'smartctl' will report SMART as "disabled" when querying the disk,
 although OS X reports the SMART status as 'OK'.
