My SystemRescueCD (bootable CD based on Arch Linux distribution) won't mount my exFAT SD card. When I plug in the USB reader, /dev/sdc appears, but it won't even show /dev/sdc1. No way to mount it, mount /dev/sdc1 /mnt/1 will fail.
It is interesting that /dev/sdc1 is recognized by cfdisk /dev/sdc - it shows that there is a free space of ~ 1 MB and then the /dev/sdc1 of ~ 64 GB. But there is no /dev/sdc1 appearing on the filesystem! If I put normal FAT SD card in the reader, the /dev/sdc1 appears correctly.
How do I make SystemRescueCD mount exFAT? Looking in /root/packages-list.txt, it contains exfat-utils 1.3.0-1. I was able to run mount.exfat and mount.exfat-fuse, but still there is the problem that /dev/sdc1 doesn't exist, and trying to mount /dev/sdc obviously results in an error.
It is rather surprising, that SystemRescueCD isn't able to do this by default, the purpose of "rescue CD" implies to me that it should be able to mount as many filesystems as possible).
(I have SystemRescueCD version 6.0.3, uname -a gives Linux sysresccd 4.19.34-1-lts #1 SMP Sat Apr 6 19:41:19 CEST 2019 x86_64 GNU/Linux; it doesn't seem that this issue would be different in the newest version)
You need to specify the type of the file system on the device, which you want to mount. Unfortunately, the
mountcommand won't do it for you automatically. So, in case of exFAT, you should do something like this:
