You might want to check if the sd card is still readable; if it isn't,
it was corrupted by being removed whilst the system was still writing
data to it; will need to be re formatted.

Should'nt it be written:

run "dmesg | tail -f" ?

Try:

tail -f /var/log/syslog

Neither one will print more than the last ten lines of kernel output at
the time of running dmesg.

Either tail -f /var/log/syslog or run something like 'watch "dmesg |
tail'.

I only wanted to print the last few line from dmesg, nothing interactive.

I would try:

- Removing the "/etc/fstab" line entry for the card
- Restarting the system
- Insert a card
- Review dmesg
- Reloading the modules
- Try with different card types (SD, MMC...)

The reader is being turned on/off.

And here is your SDHC card.

(...)

I would try with an updated kernel.

Yes it is; all the photos are still on it, and I was able to write new
photos to it.

I said in my post of 2012-03-21 at 10:34 (UTP +7):

I did so today. For Keith McKenzie's information the card I bought was
designed in the U.S. of A., made in China and branded in Thailand:
Anitech All in One CardReader, seems to read all cards currently in
captivity, very small (68 x 36 x 12 mm), comes in three decorator
colours (pink, blue and white, I chose a blue one), paid 250 baht for it
(CAD8.30, USD ±2% of CAD amount).

I plugged in to a USB port, installed in it a CF and a SDHC card and ran
command blkid. It assigned /dev/sdb1 to the SDHC card and /dev/sdc1 to
the CF card. I then modified /etd/fstab accordingly, opened Konqueror
and voilà! I was able to open both cards and copy photos from the SDHC
card to the the CF card.

The fact that blkid was able to identify these cards but not a SD card
in the built-in slot, and that this fault came completely out of the
blue without any software changes, reinforces my opinion (and John Jason
Jordan's as well?) that the cause of inability to mount and read a card
in that built-in slot was hardware failure. Surely if the hardware were
in order blkid would have identified the card in that slot and assigned
/dev/mmcblk0p1 to it, as was done in the past.

Camaléon's latest suggestions are worth trying to determine whether the
cause is a software malfunction rather than a hardware failure. To do
so however I would have to wait until I upgrade the laptop from Lenny to
Squeeze, as he suggests I use an updated kernel. I will not be able to
do the upgrade before May.

Regards, Ken
