You shouldn't do that. Although its possible to "partition" SD-Cards, this is not recommended. This is since SD-Cards have some kind of knowledge about "how FATFS works" to optimize the write cycles. This won't work if the card is partitioned. However, the best way to use SD-Cards in Linux only environments is to format them with f2fs file system. f2fs was developed by Samsung with internal behavior of embedded MMC memory devices in mind. Which is pretty the same like an SD-Card. With f2fs you also have uid/gid as usual and it will help to improve the endurance and performance of an SD-Card. cheers, Andreas -- gnuPG keyid: 8C2BAF51 fingerprint: 28EE 8438 E688 D992 3661 C753 90B3 BAAA 8C2B AF51
