I had a problem with a memory card purchased off ebay and I am after some comments.

Details:

* My Camera is a Canon EOS 450D - currently using a Sandisk 4GB Ultra SDHC card (works perfectly)
* Purchased Sandisk 8GB Ultra SDHC card - did not work (format card error)
* They resent another 8GB SDHC - also did not work (format card error)

Tested the new card in my IXUS IS100IS which is (currently compatible with my current 4GB Ultra SDHC card) and the new card did not work in that one either.

Contacted Canon and they have advised that the 450D and IXUS 100IS works with SDHC cards up to 32GB.

I also contacted Sandisk and they advised that both cards were authentic (but then again, it is ebay). Is this a case of getting sent two faulty memory cards ? I was unable to format the cards on the camera and do not have a compatible card reader for computer so I could not format it on there to test.

Any comments ?
