fdisk: unable to read /dev/sdc: Input/output error

[jiapei100]

Hi, all:

My 16Giga SD Card is now dead. Environment: Ubuntu 12.04

Phenomenon:
1)

pei@pei-GA-870A-UD3:/dev$ sudo fdisk /dev/sdc
fdisk: unable to read /dev/sdc: Input/output error

2)

pei@pei-GA-870A-UD3:/dev$ ls -l sd*
brw-rw---- 1 root disk 8,  0 Aug 15 02:39 sda
brw-rw---- 1 root disk 8,  1 Aug 15 01:17 sda1
brw-rw---- 1 root disk 8,  2 Aug 15 02:39 sda2
brw-rw---- 1 root disk 8,  5 Aug 15 01:17 sda5
brw-rw---- 1 root disk 8,  6 Aug 15 02:39 sda6
brw-rw---- 1 root disk 8, 16 Aug 15 02:39 sdb
brw-rw---- 1 root disk 8, 17 Aug 15 01:17 sdb1
brw-rw---- 1 root disk 8, 32 Aug 15 03:05 sdc

Only sdc, but no sdc1


3) GParted is not able to show details of /dev/sdc, namely, there is nothing related to /dev/sdc.

4)

cat /var/log/kern.log

gives
