Hello, I am a newbie and cannot mount my card reader. Could you take a look at this, please ?


0) Linux Mandrake 9.2, kernel 2.4.22.
SanDisk ImageMate-SDDR-93-02 with a 256 MB SD memory card.


1) I boot without connecting the card reader.
ls /dev/sd* returns nothing.


2) Then, I connect the card reader.
fdisk -l :
Disk /dev/scsi/host1/bus0/target0/lun0/disc: 252 MB, 252968960 bytes
16 heads, 32 sectors/track, 965 cylinders
Units = cylinders of 512 * 512 = 262144 bytes

dmesg :

3) mount -t vfat /dev/sda1 /mnt/test works but ls /mnt/test/ returns me
this :
zs: /mnt/test/"
¿î/.8?: No such file or directory
???àbªæ?.g(?/ à?rmh?pf.?z?/ ç??? ??(.«æ?/ dcim/ ?êd?g?h?.?c$* misc/ ?@?ö????.¡ìm/

dcim/ and misc/ does exist, but are empty here.


4) cat /etc/fstab :
/dev/hdb1 / ext3 defaults 1 1
none /dev/pts devpts mode=0620 0 0
/dev/hdb6 /home ext3 defaults 1 2

none /mnt/removable supermount dev=/dev/sda1,fs=ext2:vfat,--,codepage=850,iocharset=iso8859-15,kudzu 0 0


5) When I double-clik on "/mnt/removable" icon on my desktop, the windows does
not contain any file.


Any clue ?

Just guessing here, but maybe the filesystem on the flash card has been corrupted. I've seen a digital camera do that. You could try putting it back in the camera, saving your pictures, reformatting and trying again.

Don't try to hotplug the card reader into the USB port until there is a card in it.
You really can't hotplug the SD Cards themselves...

I always leave the card in the reader. I rather plug/unplug the reader itself.

I'll try formatting the card with the camera this afternoon.

I've formatted the card and it worked !

It's now as simple as mount /dev/sda1 /mnt/test and umount /mnt/test.

Thanks a lot.
