I have been using SDHC flash cards for data backups, reformatting them as ext4 with LUX encryption. This has worked very nicely with a mixture of cards from various manufacturers, but now I've come across a problem one. The card is a SanDisk 16gb SDHC 'standard version' (their words) that refuses to format as anything other than FAT. It seemed to format OK, but when mounting it fails (with the all too familiar log message of 'JBD: no valid journal superblock found' and 'EXT4-fs (dm-1): error loading journal').
I'm going to answer and close my own question here. I got an extremely quick response from the manufacturer's (SanDisk) Technical Support who says.... "I understand that you are trying to format the card with an ext 4 file system and LUX encryption. i would like to inform you that SanDisk SDHC cards can only be formatted in FAT file system." So there you have it. Exactly 'why' this is true I don't know for sure but anyone intending to reformat a SDHC card to something other than FAT should obviously buy another brand rather than SanDisk.
