here's the deal:
DELL sent me an extra HD for my Notebook when my last HD crashed, and I get to keep both the replacement HD and the extra HD...I was going to turn it into an external 80 GB drive, so I bought the external exclosure...the only problem is, the connectors do not fit each other...they are the same length, and I'm sure I have the right 2.5" size...but they do not match...
This is the external exclosure connector:
