Out of curiosity, if you do and wouldn't mind trading up to a new unit (same size or bigger) at nominal (or no) cost, with imaging to the new drive done for free (if you require, or you can do yourself and DBAN), email me the part # printed on your unit's case.
I'm not guaranteeing I'll do this deal, I'm just seeing if anyone has one and might be interested. Guaranteed it would be a win-win for a couple of MUUG members :-)
