Unable to mount compact flash card

Z038 · 08-02-2006, 11:32 PM

I'm unable to mount my compact flash card. I insert my compact flash card in my CF reader. I plug the reader into a USB port.

dmesg | tail shows

Code:

sdc: Mode Sense: 02 00 00 00
sdc: assuming drive cache: write through
SCSI device sdc: 2014992 512-byte hdwr sectors (1032 MB)
sdc: Write Protect is off
sdc: Mode Sense: 02 00 00 00

 sdc: sdc1
sd 7:0:0:0: Attached scsi removable disk sdc
sd 7:0:0:0: Attached scsi generic sg2 type 0

But when I try to mount it

Code:

# mount -t vfat /dev/sdc1 /mnt/cf
mount: special device /dev/sdc1 does not exist

/sbin/lsusb says

Code:

This is Slackware nearly current with kernel 2.6.15.3

I know I've successfully mounted a CF card in this reader in the past. I don't understand what the message issued by the mount command is telling me.

Probably that it's not sdc1 but something else, like sdc2 or sdc6 or sdc9 or..well you got the idea. You could

Code:

ls /dev/sdc*

and see which sdcN (where N is a number) devices are there, and try those. If no sdc devices are present, it's called something else (sg?)

OK, I tried the mount command for all my sdc* and sg* devices and got the same problem. I have

Code:

/dev/sdc10  /dev/sdc12  /dev/sdc14  /dev/sdc2  /dev/sdc4  /dev/sdc6  /dev/sdc8
/dev/sdc11  /dev/sdc13  /dev/sdc15  /dev/sdc3  /dev/sdc5  /dev/sdc7  /dev/sdc9

and

Code:

/dev/sg0   /dev/sg13  /dev/sg3  /dev/sg8  /dev/sgd  /dev/sgi  /dev/sgn
/dev/sg1   /dev/sg14  /dev/sg4  /dev/sg9  /dev/sge  /dev/sgj  /dev/sgo
/dev/sg10  /dev/sg15  /dev/sg5  /dev/sga  /dev/sgf  /dev/sgk  /dev/sgp
/dev/sg11  /dev/sg16  /dev/sg6  /dev/sgb  /dev/sgg  /dev/sgl  /dev/sgq
/dev/sg12  /dev/sg2   /dev/sg7  /dev/sgc  /dev/sgh  /dev/sgm

and I get the same error on each one, but it's different from the original error that I got for /dev/sdc1. For example

Code:

# mount -t vfat /dev/sdc10 /mnt/cf
mount: /dev/sdc10 is not a valid block device

After all this time, this problem happened to me again, but this time I figured out what was wrong. My USB CF card reader had a bent pin, so the CF card wasn't seating all the way in and making contact on every lead. I straightened the bent pin and then the device mounted normally.
