SOLVED: Re: SD card not being read from a card reader
I am having trouble reading an SD card from a card reader (USB). The
card works okay in the digital camera (Canon A520) and I can read and
delete images from the card is the camera is directly connected to the
computer via a USB cable (use digikam for the operations).

Looks like something is wrong the formatting of the card perhaps? I
It turns out that that SD card and another SD card were not mounting on
two different computers (one Debian the other running XP). So that
indicated a hardware problem. One of the pins in the USB card reader
that touches the contacts on the SD card had bent out of shape and
wasn't touching the card's contacts anymore. A pair of tweezers helped
to un-bend that pin and all is well now.
