You need to buy a couple of new CF cards. Go to Amazon and order either
a SanDisk or Lexar CF card with at least a 160 MB/s write speed. Even
that SanDisk Extreme III card is old and with read/write speed of
20MB/s is probably not fast enough to clear the buffer efficiently.

don't get them from amazon. the chance of getting a fake is high.

order from b&h, and it'll ship today if you do it in the next couple of
hours.

I usually buy from B&H or Adorama. I have bought SDHC cards from Amazon
in the past and all have been genuine SanDisk or Lexar.

with amazon, there's a rather significant risk it could be counterfeit,
despite amazon claiming they're cracking down on it.

fake memory cards are common (not just from amazon, ebay is another
source of fakes) and sandisk even has a webpage on how to check
(although a good faker could use that as a guide).

with b&h or adorama, the item won't be counterfeit unless *they* got
scammed didn't realize it. while not impossible, that's *very* unlikely
and if that did happen, sales would be halted the moment customers
noticed (a day at the most, probably just hours), so the window of
opportunity is rather small.

San Francisco (AP) -- Apple says it has been buying Apple chargers
and cables labeled as genuine on Amazon.com and has found nearly 90
percent of them to be counterfeit.

90% of 'genuine' chargers are actually fake. not an acceptable risk.
