SD cards, what about them?

[superace 2]

Hi

This is not really for UM printers but there are plenty of brain power connected to this forum that may know the answer

Have anyone also noticed that all SD cards are not equal? I have bought several SD cards in different batches from different suppliers and different brands. Sometimes these work brilliant in the printer I have but some times they can not be accessed by the printer. All works well when used with a PC but some just do not like being in a printer.

Does anyone have any ideas why? Has anyone seen similar problems using SD cards in UM printers?

I have seen this for some other embedded products too so I really would like to know why.

Thanks!

I think it comes down to the size (and possibly the class) of the SD cards. I think on the UM2 you can go up to 4GB but for the UMO it was 1GB. I am not entierely sure about those numbers though, but I remember there was something about them.
