Likely the card is stuffed. To be sure, make sure you do an 'eject /dev/sda' after you insert the card (but before you try to access it. If the error still happens, then the card is likely bad.
Some people have had luck recovering bad cards by using 'dd if=/dev/zero of=/dev/sda' to overwrite the entire contents of the card, which tends to reset all the erase status of all sectors as well as resetting the internal state machine of the card. As usual, YMMV. Matt On Sun, Aug 10, 2003 at 12:31:13PM -1000, Graeme Merrall wrote: > Not exactly sure if this is USB related.
