Title: Not sure about these
Review: I bought 2 of these prior to a major trip. I tested each card, about 40 pics per card, before the trip. While on the trip, I lost about 150-200 pictures with no explanation. Other pictures ended up with corruption problems. I used a Nikon d70. I have 2 other compact flash cards I have had for a few years and they had no problem. I can't tell if these are real or fake. The articles I read mainly show these with an Ultra II on them, which the older cards are. When I bought these, they were shown in the online picture as Ultra II with a write speed of 15 rather than 30. I really wanted those, but kept these after I tried them. Since I have been using digital for about 12 years and this is the first time I have had a problem, I can feel there is a problem with the cards. Unfortunately, it has taken me about 6 months to track down information, first looking and the camera for problems and then Photoshop.
Is the review positive or negative?
