just want to know if i could use the 8gb sdhc flash memory card with a psp

My R4I will not work on my DSI XL, why not? A few weeks ago i bought a new r4i sdhc card because i thought my other one broke but my new one just came up with the same message :

An error has occurred.
Press and hold the POWER
Button to turn the system off.
Please refer to the Nintendo DSI
Operations Manual for details.

But I referd to the manual and it did not help.
WHY ?????

Most 16gb cards on the internet seem to be SDHC.Can I use these on my Panasonic DMC-FS15 camera?

Will a Transcend 8GB SDHC work in my Canon FS 100? The instruction book states that the camcorder has only been tested using SanDisk, Panasonic, and Toshiba SDHCs, are they just saying that? Will any SDHC card work, or is it true that only certain brands will work?
How about an HP SDHC card?

hey, im deciding between a 16GB and an 8GB but i need to know how many pics an 8GB will hold so that i can decide!!! thanks

I just want to get one from a place i know its not gonna take 2 months to get it. I certainly dont want one from China. So where do i get one thats reliable and doesnt sell knock-offs? I dont wanna cross the limit but if i must i guess i will.
I would prefer a USA seller
…and one that has it IN STOCK !

I’m not really a computer person. I only know my gadget says it will take a 16 gb micro sd card, so will it also take a Micro SD HC SDHC card? I need to make sure I’m buying the right thing.

What class memory card is better, a class 1 memory card or a class 10? I assumed class10 would be better and purchased it, even though it was cheaper than the class 1 memory card, but it has a very slow reaction time when I zoom in and out, and every time I try to record, the screen says "too slow card". What does this mean?

i need to know what memory cards are compatible with that camcorder. please help
