SD card mystery

[Abarbarian]

Well I have a sd card reader on my monitor that reads old sd cards that I have.
I have a usb card reader that reads old sd cards I have.
This is both in Arch linux and Windows 7.

I bought three different types of sd card.

They will not show up in linux or windows or the Parted Magic live cd.

How do I get them to show so that I can use them ??

I tried with a sd card in the monitor and a sd card in the usb reader,

$ df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 15G 4.5G 9.4G 33% /
dev 1.9G 0 1.9G 0% /dev
run 2.0G 384K 2.0G 1% /run
/dev/sdc5 15G 4.5G 9.4G 33% /
shm 2.0G 0 2.0G 0% /dev/shm

/dev/sdc7 9.8G 42M 9.7G 1% /tmp
/dev/sdc6 9.8G 2.8G 7.0G 29% /var
An they do not show up.

As you can see in the screenshot the two card slots for the monitor and the two slots for the card reader show up in spacefm file manager but do not show any cards inserted even though cards are in place.

What the heck is going on. Any ideas folks.

How old are the card readers? It could be that they can't handle the higher capacity CD cards - I've got a USB card reader that won't do any SD card above 2GB.

The card reader is a couple of years old so is the monitor. Both read me 4 GB flash cards and they used to read sd cards.The new sd cards are 4 GB.

The newer SDHC cards are 4GB and above, anything under that and they are just standard SD cards!

Think I found the answer. Seems like SDHC cards need a newer reader. So it is of to the shops for me.

It is always a good idea to buy a newer card reader if you are buying a card after two or three years. The newer card readers are always backward compatible. Many SDHC card readers also do not read the SDXC cards so it is necessary that the compatibility is there.
