I have a sandisk compact flash card reader and I was wondering how I can access it in linux.

It should be a USB mass storage device, which should be as easy as:

modprobe usb-storage

Then assuming that you haven't got any exciting SCSI devices already in your system... yeah basically everything in Linux that is a weird device is emulted as a SCSI device:

Make a Directory for everything to be mounted to:

mkdir /mnt/flash (you could call it bob if you like, flash is just a suggestion)

Now mount the puppy:

mount -t vfat /dev/sda1 /mnt/flash

At this point the directory should be browsable. To make it so it comes up on boot, add this to the bottom of /etc/fstab

/dev/sda1 /mnt/flash vfat noauto,user,fat=12 0 0

This of course, may not work, post back where you get stuck and what hiccups.

Cheers,

Finegan

check this link out it helped me bigtime and its funny too

Hey finegan,

I was having trouble getting my cfcard reader set up and then I found your instructions here at linuxquestions.org. I followed them exactly as you said and everything worked perfect.

However, because of reasons I will not elaborate on, I had to re-install rh8.0. Then I went back to your instructions on mounting/setting up the cfcard reader but now I get this error message:

[root mnt]# mount -t vfat /dev/sda1 /mnt/cfcard

mount: /dev/sda1 is not a valid block device

I'm sure there is an obvious fix to this problem but I cannot find it. Any ideas?
thanx.

When you plug in your cfcard reader type this into an xterm first:
tail -f /var/log/messages

This will show you what the device is being called. If you have questions after doing that, post up what it brings up, and maybe also some relevant sections in dmesg and your /etc/fstab.

Cool

Hi. Sorry, this is a lot of stuff but here is goes. The light on my card reader is lit so I assume the drivers are loaded. Thanks.

It truly looks like it should be registering as /dev/sda1

How exactly are you mounting it, and as what user? Try this as root:
mount -t vfat /dev/sda1 /mnt/wherever

Make sure /mnt/wherever exists.

Cool

It works. I guess I wasn't doing it under root. I thought I was. I think I better lay off the smoke. Thanks for your help.

he he he, the smoke

You can mount it as a regular user if you add it to your /etc/fstab and place the "users" entry in the options column.

Cool

hi, i posted this in the "newbie" forum but didn't really much help. i have a combo memory stick / cf card reader, can i follow the above directions to mount it/them? under windows it shows as 2 separate drives. btw, the light on my reader is currently lit if this important. thanks.

This should work, if it registered right as a scsi device then one of the ports is probably /dev/sda1 and the other /dev/sdb1, give us the last 15 or so lines from dmesg and we can tell you for sure... or even if it got found correctly.

Cheers,

Finegan

Well, here goes from dmesg (sorry it's so long, not sure all is needed):

Odd, there's two reads there on the same block, did you pull it and then plug it back in? Regardless, yeah man it sees the thing, sees its a mass storage divice, nothing was plugged into it at the time right?

The above directions should more or less work.

Cheers,

Finegan

Yeah. My hardware: I've got an Adaptec Duoconnect PCI card (USB 2.0/firewire), which I currently have a scanner connected to the usb port, and the card reader is currently connected to mobo usb port. In future I will also have a printer hooked up (waiting for my usb cable ). Will need more help on scanner, printer, and camcorder (firewire port) later .

From above:

is that a command line I type into the Konsole, and the make a new directory? Sorry for all the questions, extreme newbie here.

From your dmesg it doesn't even look like you need to modprobe usb-storage, that got done automagically for you when uhci saw that something was connected to it. Just make a directory to mount it to, like: /mnt/bobstoy and then add an entry in /etc/fstab like:

/dev/sda1 /mnt/bobstoy vfat noauto,user,fat=12 0 0

Then after you pop a card in, all you have to type is:

mount /mnt/bobstoy

And then the stuff should be there.

Cheers,

Finegan
