Why my SD card reader doesn't work in Arch?

My SD card reader named SSK doesn't work in Arch. The error message in /var/log/messages.log is:

The SD card's partition table is FAT32, other U disk works well. I suppose maybe ArchLinux cannot drive the SD card reader.

Thanks.

Re: Why my SD card reader doesn't work in Arch?

Your card reader might be finicky like mine. Figure out which device your card reader is at (from what I'm reading probably sdb), then attempt to mount /dev/sdb to any location. If your card reader is like mine, this mount will fail but you'll find you now magically have /dev/sdb1, /dev/sdb2, etc devices, which will successfully mount... oddness, but it "just works" so I'm happy

Note that if you plug a card into a slot that is to the kernel, for example, /dev/sda2, then try to mount /dev/sda1, this will (obviously) fail, so be sure to try mounting all the devices that magically appear (if any do).

Thanks, dav7.

I will give it a go and hope it works.

Re: Why my SD card reader doesn't work in Arch?

Sorry, dav7, it doesn't work at all.

Actually, when I plug the SD card in, there is no /dev/sdb file created. So I cannot `mount /dev/sdb /media/xxx' and obviously I cannot mount /dev/sdb1, ... etc.
