I put 1Gb MiniSD card to Nokia 6280 and it worked fine as long as tried to write data to card. Then the phone was hanged. When I put memorycard to my laptop, I can read data from the card. I can't format it and when I try to write data I get Data error (cyclic redundancy check). I even tried to format it with Low Level Format tool and I got Format Error occured at every offset.
Could somebody explain how memorycards are working? Is there also microcode and modules and if there is how can I access to modules and microcode?

Hi PixPrit,
If your main goal is to reuse your card. First look on the manufacturer web site to find out if it still under waranty if yes then return it. If no throw it and go get an other one. Those flash media are really not reliable enven if you'll be able to fix them you shouldnt reuse them for "Normal purpose".
If your goal is to get the data back low level formating it its not the best way to achieve it.
First try to image your media (For myself I use linux dd_rescue) then work with high level DR software.
Regards

I do not have any valuable data on that memorycard and my interest is to learn more about memorycards and if it is possible then fix this card. I already replaced one such card from new one, because same thing happened to this previous one. I'd like to understand how phone can destroy memorycard. I belive it must be some firmware problem, but how to access to memorycard firmware? I already tried linux dd command also and it gets some I/O errors (don't remember exatly).

To work with the SA of the memory card the only tool i know is pc3000 pci .

How can I connect memorycard to pc3000 pci?

Dear Only CF (compact Flash) card can be attached in PC3000. You cannot attach any other card in it.

I thought so, because I have IDE to CF adapter and I can connect CF through that adapter to pc3000 pci. So how can I access to SA of SD and other memorycards?

You cannot connect other cards only CF can be attached. Possible only when there is converter like SD to IDE or MMC to IDe but i dont think any such thing exists.
If you got any solution please let me know.

Hello,
since only CF cards have IDE-like interface it is completely nonsense talking about converters from other cards to IDE in a similar manner.
Flash memories doesn't have a FW area, but a small configuration sector and some area to store the damaged blocks mapped out already.
The only way to access these areas is to read the memory itself leaving its controller out of the process.
In this case it is not about the data but rather to save the card itself, so it is not worth to make such efforts.
regards,
pepe
