Your issues are more likely to be hardware related. Do make sure you are using a recent enough card reader for the capacity of the cards and it's also properly connected / powered (i.e. not through your defective USB hub you discovered at some point). Of course, the card itself may just be defective ;) Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
