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
tmpfs		   9.8G   42M  9.7G   1% /tmp
/dev/sdc1	   242M   19M  211M   8% /boot
/dev/sdc8	   113G   16G   92G  15% /home
/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 (sdd + sde) and the two slots for the card reader (sdf + sdg) 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.

As soon as you insert the card, open up a terminal and type:

dmesg | tail

to see if Linux recognizes the media.

That "dev fd0" is my non-existent floppy drive.

Sorry I have no idea. If it cannot read the cards in Windows, Linux, and a livecd; I would think that it is your drive messing up but you tried it with both the monitor and an a usb drive

  this just happened to me the past week! Through error and trial I found out that in my case, if the motherboard/BIOS was more than 5 years old it wasn't going to work .

#  fdisk /dev/sdd
Welcome to fdisk (util-linux 2.21.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

fdisk: unable to open /dev/sdd: No medium found

I get the same for all four slots.

Flash drives work. I do not have a old sd card here as they are all in York at me mums.
Surely I can not have three duff sd cards ??

Well it would be sde1 not sde.

Never mind, I was thinking about mounting.

If the cards are 4GB or larger than they might be sdhc cards. Not all card readers can read them.
I have a gizmo   to which I insert a card (sd, sdhc, micro sdnc in an sd holder) that I attach to a USB port. Even my old Win 2K computer can "see" sdhc cards when I plug it in via USB.

By golly gosh I think you deserve a couple of pints or cocktails.
They are sdhc as advised by the Pi folk.
Mow I have to buy yet more equipment. Darn. That means an even longer wait to fire up me Pi.An an even longer wait to see those beautiful tattoos.

SDHC adapters should only run a buck or two.

SD card reading solved with the purchase of a £1.00 reader from the local PoundShop. I had to think long and hard about the purchase as £1.00 is a lot of money for a tyke to spend all in one go and they had a choice of colours which made the task even harder.



I bought a blue one to match my blue and black pc center theme.

[securitybreach]

Glad you got it working

[ross549]

Now, here is the important question... is the reader compatible with SDXC?

There are three SD specs out there.....

SD
SDHC

Good Q. No it is not but for an outlay of £1.00 I think I can live with it. Maybe

Josh I have ArchArm installed on the sd card. Just waiting for that darn cable to arrive. I could have got one locally for £6.00 but I went for the Buy One Get One Free deal at e-bay at a whooping £1.98 inc postage. I'm a paitient sort of barbaian and I am only up to episode three of the tv series of Smiley's People.
