SD Card Corruption Issues

[SDFUK]

Hi,

I am having some problems with the /sd partition. It seems to be that data and module scripts are regularly getting corrupted.

It's reasonably common for me to find that the current directory I am in (on the SD card) currently has no content. Sometimes I can run fsck to fix this but not always. Example dmesg output is below.

Is this an issue with my SD Card or something else?

Thanks
