Fixing Partition One On Ts-7260 sdcard image

The sdcard image consists of 3 partitions. I found that these partitions will somehow corrupted due to force reboot by watchdog. So, to fix the corrupted first partition is by rewrite it using 'dd' tool with the original partition image.

I have saved and keep the original image for the 1st partition here at http://jerungkun.googlepages.com/ts7260-fb-default.tar.gz

In order to use it. Download the image:

apogee@apogee-persiasys:~/Download$ wget -c http://jerungkun.googlepages.com/ts7260-fb-default.tar.gz

apogee@apogee-persiasys:~/Download$ 

Next, extract the image:

apogee@apogee-persiasys:~/Download$ tar zxvf ts7260-fb-default.tar.gz

Insert the sd card and check with fdisk -l:

apogee@apogee-persiasys:~/Download$ fdisk -l

Disk /dev/sdc: 1015 MB, 1015808000 bytes
16 heads, 32 sectors/track, 3875 cylinders
Units = cylinders of 512 * 512 = 262144 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System

apogee@apogee-persiasys:~/Download$ 

From the fdisk output above, we can see the first partition is /dev/sdc1. so, to overwrite this partition, simply run this command:

apogee@apogee-persiasys:~/Download$ dd if=ts7260-fb-default of=/dev/sdc1
2808+1 records in
2808+1 records out
1438184 bytes (1.4 MB) copied, 0.958003 seconds, 1.5 MB/s

That's all.. to make sure the other partition is in good condition too, just run fsck on em. But make sure u have already unmount em all first:

apogee@apogee-persiasys:~/Download$ sudo umount /dev/sdc2
[sudo] password for apogee:
umount: /dev/sdc2: not mounted
apogee@apogee-persiasys:~/Download$ sudo umount /dev/sdc3
umount: /dev/sdc3: not mounted
apogee@apogee-persiasys:~/Download$ 

then run fsck:

apogee@apogee-persiasys:~/Download$ fsck /dev/sdc2
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
/dev/sdc2 was not cleanly unmounted, check forced.
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sdc2: 117/128 files (5.1% non-contiguous), 989/1024 blocks

apogee@apogee-persiasys:~/Download$ fsck /dev/sdc3
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
/dev/sdc3: clean, 28501/242000 files, 484287/987136 blocks

that's all.. the card should be in good condition now... we can use it again without error. You should also do ths too before creating the image so all newly copied cards is in best conditions.
