The Connecticut Secretary of State requested that the UConn VoTeR Center perform a pre-election audit of the memory cards for the Diebold Accu-Vote Optical Scan tabulators used in the August 2008 Connecticut Primary Elections
The audit found that of 185 Diebold voter cards, 175 were found to be properly programmed, the rest contained junk data. The machines are supposed to be able to detect this, so supposedly the cards could not be used in an election. 5.4% is a high failure rate when trying to prevent chaos on election day. The cards were shipped to UConn directly from the vendor, LHS.
This failure rate doesn't surprise me at all. Just look at Voters Unite's llong laundry list of problems with Diebold (that we know about) over the past several years. Standards for voting vendors are terribly low, they've been given a free pass for too long.
