I have a sales guy telling me at http://www.macconnection.com/ that an eide drive (theirs) will work on an IDE system. Is this true. As stated before I don't know if my system is ide or eide. I have an IBM NetVista computer. This is what they're trying to sell: Open Box Western Digital 160GB Caviar SE EIDE 3.5" Hard Drive - 8MB Cache -- :-)~MIKE~(-:
