Any driver updates performed since then?
Do both machines have similar SATA controllers and drivers?

Could not reproduce this.

The Windows IO-controls IOCTL_ATA_PASS_THROUGH or SMART_RCV_DRIVE_DATA 
possibly return some unexpected error code. This is typically a SATA 
driver issue. The output of "smartctl -r ioctl,2 -i /dev/sda" should 
provide more details.

Could you possibly repeat the above test this with the "native" 
(non-Cygwin) Windows version of smartctl?

This is likely not a Cygwin specific issue. Smartctl does not use any 
Cygwin functionality to do ATA/SCSI pass-through access. Cygwin and 
native version of smartctl share the same code. We could continue the 
discussion by private mail or on smartmontools-support mailing list if 
desired.
