We present results from an ongoing archival search for X-ray emission from all known Type Ib/c supernovae using data from the Chandra X-ray Observatory. For each supernova, we search all possible observations to find those with coverage in X-rays. For those observations with coverage of a supernova, we extract an X-ray spectrum at the location of the supernova and create response files. We model those spectra with an absorbed hot plasma model in order to determine luminosities or set upper limits. These results are then used to determine or set limits on the mass-loss history of the pre-supernova stars, thus giving insight into the late stages of stellar evolution.
