Hi,

I followed that USB reader/writer howto, which was very good, but I ran into trouble at the very end.

I ran the final command to mount the reader, and I got the error
>mount: no medium found

Can anyone help me solve what I hope is not a serious problem...??

Regards,
Triona

well, you tried to mount it, but theres no card in it. put a card in, and try again.

No, I've a card in it! I've been googling all afternoon. and following the advice I found on a link, I rebooted the kernel, but no luck.

This problem seems to be common enough, but no solution!

The device in question is a 6 in 1 card reader. I have a MMC card in. Surely I don't need more than one card in the slots?

hmm. 6 in 1. thats your problem, I think. Its looking in one of the wrong slots, correct me if im wrong, but the howto you read was for card readers in general, not just 6 in 1's? I think there may be seperate devices for each of the slots. Can you post the mount command you are using?

Hi,

Thanks for your reply. Sorry about the delay.

I think you're right. I am after mounting one (the wrong one at that) device in my fstab file.

This is what is expected when you follow the howto:

I got:

So after the other commands...

#mkdir /mnt/USBdrive
#chmod 700 /mnt/USBdrive


# nano -w /etc/fstab

/dev/sda1 /mnt/USBdrive auto user,rw,noauto 0 0

This is obviously wrong as I'm not on sda1. How do i mount the four seperate devices to the one folder?

# mount /mnt/USBdrive

Here is where I get my error (No medium found)

I'd say it would work if I just changed the "sda1" in fstab to "sdc", but it would be better to get them all in.

well, first check if using a different device works. try sda2, sda3, and so on, if that fails, then try sdb1, sdc and so on...

I've got problems in the start of the manual: I compiled kernel as it was said in the manual, but when I type cat /proc/scsi/scsi I don't get any info about devices.

Sorry about the delay, I had exams so left my project for a while...

I'm a bit confused now, as I tried again to see if I could try every device like you advised, and now when I "cat proc/scsi/scsi" it is empty and only says "attached devices:".
Is there a way to recover this as I don't even have an idea of how it could have happened?
