For One Chip related machines:
2GB SD/micro SD cards are difficult to find. I recently updated my Zemmix Neo firmware and one of my SD has stopped working. Previously I bought two micro SD of 2GB at Amazon and did'nt work and now with the new firm neither.

SO, WHICH BRAND OF 2GB SD DO YOU USE IN YOUR OCM MACHINE AND WHERE WE CAN ALL BUY IT?

I have old SANDISK micro SDs that work fine...

Hello, you can use also 4Gb SD if they are easier to you to find, I've successfully tested a Fujifilm 4Gb SDHC.

I still have some Kingston 2Gb that I bought at the time to keep in reserve. The one you can still buy is the 2Gb Transcend, it works very well for me.

A good SD is very apreaciated by our Zemmix, I notice a big difference in performance between a good and a bad SD.

Thank you AxelStone for all the info!
I upgraded my Zemmix Neo to 3.9.1 firmware and my Transcend card stopped working, so I decided to go back to firm 3.8.1, that in fact I'm happy with it and as a normal user I don't see any difference between firmwares.

Talking about 4GB SDHC, I use DOS2 (not Nextor) and as far as I know, DOS2 can only handle 2GB. If it is so, can I partition one 4GB SDHC card with any DOS2 application and can use that 4GB card with two 2GB partitions with Multimente?

@selios2000 I use also DOS2 and believe or not, 4Gb SDHC is accepted. I also thought that 2GB was the limit because is the max size for a normal SD, but 4Gb SDHC is also suported. 8Gb SDHC definitively doesn't work.

About your problem, the firmware shouldn't affect, I've updated to 3.9.1 and all my SDs still work, including the Trascend 2Gb and Fujifilm 4Gb SDHC.

I know it is strange, but believe me it happens...
I have Lexar 4GB that don't work, so I will look for Fujifilm! Thank you very much!

Very strange, you could report the bug in the official thread so KdL / HRA can check it. Perhaps OCM firmware has some error, in Zemmix I didn't notice any problem with the SDs.

In fact, the fastest one of all of them is the 4Gb one, is reaaally fast!
