Sd card not working properly

tokka

Hi all, i have a strange issue
I'm trying to make an sd img to uplaod, using a sandisk 4gb card, but seems it doesn't want to works on op. If i use another card (a kingston) it works without problem (the card is damaged, and the os run slow), but the same img on the sand disk don't want to boot..the green led is fix, the lan led flash, but nothing more.
If i use the sandisk with a cubieboard it works without problems.
This thing is drivin me crazy
Do you know if there is some incompatibility between op and these cards?

Class 10 is shure better, but usually i use it only as boot partition (a sort of bios ), with all the os on hd.
Both my cards are class 4, but i don't understand why one wan't works

Class 10 does not guarantee operation. I fooled around with 2 identical brand new sd cards off and on for 3 months. One image worked fine, set that card aside. Couldn't get any other image to work. Tried a different sd card yesterday and all of the failed images work on the alternate card! Non functioning card is a Kingston class 10 that works fine in other devices.

Thanks for sharing Survive
So, it seems hard to find a card working on all oranges, and at the same time, build a sort of database with working/no-working card seems impossible

I just broke mine. My card is sandisk ultra 64 GB. I used the Win32DiskImager-0.9.5 to write OrangePI_Jessie_Xfce.img. The result I can't load the OS. I have 4 partitions unallocated 20 MB, Boot 64 MB, linux 1.77 GB and unallocated 57.63 GB. Please HELP. When I try to format it with SDformatted via USB card reader i get error message - card is write protected
