A Florida law professor came to the California vote panel in Sacramento on April 22 and testified about this problem.
She wanted to let California know because one of their counties uses the same equipment.
She felt like it might NOT be just a flash card or audit log problem.
If you want her testimony, you can find it at a pdf

Martha Mahoney.
Law professor at University of Miami also has done civil rights stuff ... iVotronic made by ES&S ... is used in one county in CA - Merced. We in Miami Dade are having a big problem with audit logs of these machines. In the audit logs, serial numbers of machines disappered. On one study 38 ballot events disappeared. We're talking, in my opinion, about extremely serious problems with integrity of the machines. ... They think it is caused by storing the data on flash cards. That's the short overview. I'm not yet convinced it's all flash cards. Haven't gotten my public record requests yet. The audit review used the PDB device, still found non-identical.
Are the redundant memory systems truly identical? It isn't a question we're supposed to be asking, it's a question posed based on our findings. ... It wasn't caught until this gentleman did a study.
I actually think it's not the flash cards causing it. I think it's another systemic problem.
Florida is in my opinion taking a 'don't ask don't tell' approach to the problems coming up with electronic voting. ES&S is saying it's only flash cards and only Miami, where the trilingual ballot is.
