smartctl -a gives here:

As you can see, in the SMART attributes, the life time (Power_On_Hours) is OK: 66120. But in the log, it has wrapped at 65536.

Found in 5.38 and svn revision 2879 Original bug report: ​http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=535298

1. Downloaded smartmontools-5.39-1.win32-setup.exe
2. Installed with custom-type install; selected Program FIles, Uninstaller, Add install dir to PATH, Add (smartctl -a | smartctl -t long) into drive menu.

Installation has been completed successfully.

The items in drive menu doesn't work. I extracted from the registry that smartctl -a invoke "C:\Program Files\smartmontools\bin\smartctl-run.bat" -a %L

But there is no "C:\Program Files\smartmontools\bin\smartctl-run.bat" installed.

I don't know what's the function of smartctl-run.bat ...

When I install smartmontools via MacPorts? (default build), the 'smartd' daemon is automatically registered as a StartupItem?. After that, it will periodically - every 30 minutes - query my harddisk and log the following:

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

during which my computer freezes for about five to ten seconds (possibly because not HDD access is possible). 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 and smartd work fine without freeze).

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