re: cuperacion de memorias flash
cuando insertes la memoria en el puerto usb, fijate en los mensajes del kernel con 'dmesg' y fijate en lo que dice. Cuando pongo la mia se ve esto:

Eso quiere decir que la detecto y vio que tiene una particion (sdb1). Si puedes montar la memoria y ver sus contenidos, copialos y sigue observando los mensajes (tambien puedes monitorear el /var/log/messages) y ver cuales de los archivos dan "Input/Output error": esos son los dañados.
Cuando hayas completado lo anterior (o si te rendiste porque ni siquiera ve las particiones), usa fdisk o cfdisk o qtparted para editar la tabla de particiones a tu gusto y crear el sistema de archivos que prefieras, siempre utlizando la opcion de marcar los bloques dañados.
Suerte.

postea el resultado de lo siguiente:
lsusb
ls /dev/sd*
averigua el comando mkdosfs para que hagas una nueva particion fat16 en tu memory..

cuando posteo esta es la respuesta
[root@centauro log]# ls /dev/sd*
/dev/sda /dev/sda2 /dev/sda4 /dev/sdb
/dev/sda1 /dev/sda3 /dev/sda5 /dev/sdb1
Si tienes un disco duro sata
Si tienes un disco duro sata tal vez esa sea /dev/sda, entoces la memory es /sdb
prueba lo siguiente
mkdosfs -F 32 /dev/sdb1
o dependiendo de la antiguedad de tu memory puede ser
mkdosfs -F 16 /dev/sdb1
Cogito Ergo Sum

Cogito Ergo Sum
por las dos opciones esto es lo que me muestra
[root@centauro log]# mkdosfs -F 32 /dev/sdb1
mkdosfs 2.8 (28 Feb 2001)
[root@centauro log]#
[root@centauro log]# mkdosfs -F 16 /dev/sdb1
mkdosfs 2.8 (28 Feb 2001)
/dev/sdb1: No such file or directory
aclaracion
dejame decirte que esto me esta ocurriendo con una memoria de una companera que parece que se le jodio y estoy tratando de salvarla, con otras memorias el sistema la reconoce ok e incluso en algunas trabaja el autorum y puedo trabajar bien
Parece que con la primera
Parece que con la primera opción no hubo problemas, trata de montarla con
mount -t vfat /dev/sdb1 /ruta/carpeta/
además dime lo que sale con
lsusb
