[Asterisk-Users] Asterisk 1.0.2, Zaptel 1.0.2, Linux 2.6.9 on a PCEngines WRAP\Soekris net4801 in Compact Flash

[Goran Obradovic]

I had huge production problems with CF cards just a month ago. I used to
live in Canada and still have some business there - electronic voting
equipment. So, we have optical voting devices with 256, 512, and 1GB CF
cards for election definitions and voting records. Last month on Alberta
elections we had 5 Kingston 256MB cards failing during the elections. That
was a nightmare. It is interesting that 512 and 1GB cards were ok even with
more writes. In any case, if you do something like this first test some
cards for long period of time. Make some script that will constantly write
and read the card and see when they fail.

Sounds cool, but I heard a rumor that CF Cards don't like too many rewrites
or 
they start losing data.
