64GB sdcard only reports 64KiB
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!!!

Just realized, another explanation is that my card reader doesn't support cards this big :-( -- Brian May <brian@linuxpenguins.xyz> https://linuxpenguins.xyz/brian/

That's plausible. Is it SD or micro-SD? The full size SD cards are old and might be prone to such compatibility issues, but I've tried plenty of larger micro-SD cards without having a problem. Does it work in your phone? I can bring a reader to the next meeting to test if you want. As an aside, I dumped a heap of adapters to use micro-SD cards in devices that want full-size SD cards in the hardware library some time ago. There are probably still some in there. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

micro-SD. I found a recent computer with a SD card reader, using an adaptor and it works. So assuming that all my other readers (some SD and one micro SD) are too old.

My phone doesn't have any expansion ability.

There are a number of SD standards.... SDSC (Standard, original SD) SDHC only up to 32GB SDXC 32GB to 2TB Perhaps the "reader" isn't capable of the version that you are hoping to use. Being a 64GB card, it must be SDXC and your reader is probably just SDHC. Cheers A.
