Topic 1: SD CARDS
Q: I want to buy an sd card, which one will work?
A: The BlueAngel does not accept SDHC cards. Compare your sd card to the following images:
a) shows an example of a standard SD card, that offers full compatibility with the BlueAngel
b) shows an SDHC card, which is incompatible with the BlueAngel. When buying a new card, make sure, the SDHC logo is NOT present.
This means, that the maximum capacity, you can use with the BA, is 4GB, because 4GB cards exist both as standard SD and SDHC.
Changes to the interface of the established format have made some older devices designed for standard SD cards (up to 4GB) unable to handle newer formats such as SDHC (starting at 4GB). All SD cards have the same physical shape, which causes confusion for many consumers.
Q: But I found SDHC drivers on the forum, won't they make it work?
A: NO, it won't. While for other devices there are actual working sdhc drivers, there are none for the BA, no matter where you found them, they won't work!
Q: What do the numbers on the sd card mean?
A: The number in the circle gives you information about the sd card's speed.
There are the following classes of sd cards, giving the following writing speeds:
- Class 2: 2 MB/s
- Class 4: 4 MB/s
- Class 6: 6 MB/s
- Class 10: 10 MB/s
As you might have guessed, the higher, the better.
Q: My card does not have a class, it has a 66x (or any other x) rating, What does that mean?
A: The × rating is a unit of measurement equal to 1.2 Mbit/s. It is derived from the standard CD-ROM drive speed. See the conversion table below for details.
Q: I saw dedicated cell phone cards, some others seem to be for digital cameras, what's up with that?
OR: On the back of the packaging, there is a compatibility list of devices, but the BA is not on it. Is this a bad sign?
A: It does not matter at all. Since the BlueAngel is a smart device, it can take just about any card, that meets the size restrictions. The mobile standard was introduced, back in the day, when mobile phones could not deliver the voltage needed for standard storage cards.
Q: Should I format a new bought card?
A: Although many cards come pre-formatted, you should never start using it right away. This is for 3 reasons:
1. Recently it was uncovered, that a manufacturer (not to be named here) shipped storage cards with a virus on them.
2. There could be crap on the card, that nobody needs (just like on new external hard drives).
3. You should make sure, it is formatted correctly for the best stability. See the picture below for the optimal way to format the card:
