On some SDHC card, a low level formatting is required, info here, http://www.internettablettalk.com/fo...051#post137051, thread #24.

@Milhouse: Does 'wipe' include low level format?

The low level format is REQUIRED for Adata SD cards. There are few posts that people do not have to do the low level format and succeeded, this thread #264,#266, and 3 more. I am interested to know what kind of SD cards they are using. Their SD cards probably more conformed to the SD standard than Adata.
