This is a harmless bug in a Cygwin specific patch: The string buffer is 
not cleared if IOCTL_STORAGE_QUERY_PROPERTY only returns a Product ID, 
but no Vendor ID.

Is already fixed in my local git and will be fixed in next Cygwin package.

The upstream version of ddrescue 1.21 does not print any device identity 
if built on Cygwin because this patch is not included (it was rejected).

Thanks,
