What you want is direct SCSI access which is only available through native Windows calls. You have to figure out the name of your loader in the Win32 or native NT namespace and open the device with CreateFile or NtOpenFile. Then you can either use the IOCTL_CHANGER_* class of DeviceIoControl codes, as far as they match what you're looking for, or you can use the IOCTL_SCSI_PASS_THROUGH DeviceIoControl code for direct SCSI device access. Whatever you do, you have to use native Windows/NT function calls since generic scsi devices (sgX) are not provided by Cygwin.
