Both Linux and Windows have problems with this card. However the Thinkware f770 dash camera seems to be fine. Can record and playback without any problems. So seems that the the SD card really is storing more then 16kb. Any ideas? Disk /dev/sdc: 64 KiB, 65536 bytes, 128 sectors 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/sdc1 * 32768 125106175 125073408 59.7G 7 HPFS/NTFS/exFAT Command (m for help): Later, ok this is weird. Tried "cfdisk -z" and now reports "Size: 477 GiB, 512110190592 bytes, 1000215216 sectors" - the sdcard isn't that big!!! How do I get back sane values??? -- Brian May <brian@linuxpenguins.xyz> https://linuxpenguins.xyz/brian/
