I have two SanDisk Extreme 60MB/s 16GB CompactFlash cards that have developed an audible rattle. I believe both still work to store and transfer data, but the rattle makes me nervous that something internal has broken free and is moving around inside and could potentially cause a short circuit. I just purchased a third of these cards and it does not have the rattle. In addition, I have three Extreme III 30MB/s 8GB CompactFlash cards (one of which has even gone through a cycle in the washing machine in a pants pocket) and none of them exhibit the rattle.
Does anyone know the construction of CF card enough to know whether there is any potential for a short circuit to happen and damage either my camera or card reader/computer? I'd figure this is a long shot, but I don't know enough about the internals of CF cards to rule it out.
Additionally, does anyone else notice this with any of their SanDisk cards? I notice the rattle if you gentle tap on the card or shake it (hold it by two of the corners on a diagonal for the most noticeable rattle if it is the same as mine).
Lastly, if you have had this happen, did you try getting it replaced under SanDisk's lifetime warranty on these cards? According to their website, these cards are "Tested in harsh conditions this card is temperature proof, shock proof, and x-ray proof" - I would figure something breaking inside would violate the 'shock proof' aspect of that... but I wonder if still reading data means it is still functional enough to not be covered under the warranty.
Thanks in advance!
