Are the failures actually "random"? Do different runs of smartctl return 
different results?

The above suggests that the IDE driver lacks full pass-through 
functionality (IOCTL_ATA_PASS_THROUGH). Try with -r ioctl,2 to see which 
IOCTL is used (PLEASE use attachments for sample outputs).

IOCTL_ATA_PASS_THROUGH is supported by the generic MS IDE drivers since 
XP and by the generic MS AHCI driver since Vista.

Please check in device manager which driver is used for the (which?) 
SATA controller. Switching to AHCI mode may provide better results.

I never used Win7PESE. Smartctl works as expected with both IDE and AHCI 
mode if run from a Win7 System Repair CD.

Thanks,
