Are you sure that this is not just another example of "Flash Fraud"? You could try running https://github.com/AltraMayor/f3 . > Hi, > As supplied the SD cards are intended to work with Windows.

SD cards usually come with a vfat file system and are indeed set up mainly for Windoze. But if you mount with -o uid=someone,gid=someone,.. then that someone user can write. I do this all the time with a whole variety of sdhc cards. I only leave them formated for vfat if I need to move them between other devices (cameras, sat navs, ereaders which only read and write vfat). Otherwise I use a better file system. > > root@aragog:# /sbin/fdisk -l /dev/sdb > Disk /dev/sdb: 27.48 GiB, 29504831488 bytes, 57626624 sectors > Disk model: Card-Reader > Units: sectors of 1 * 512 = 512 bytes > Sector size (logical/physical): 512 bytes / 512 bytes > I/O size (minimum/optimal): 512 bytes / 512 bytes > Disklabel type: dos > Disk identifier: 0x00000000 > > Device Boot Start End Sectors Size Id Type > /dev/sdb1 32768 124735487 124702720 59.5G 7 HPFS/NTFS/exFAT > > I don't know why the size is reported differently in two places.

Yes. Almost certainly a fake.... ael _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
