How to copy data on SD in a phone to the other SD in the other phone

These 2 phone are connected with USB cables to mother PC.
After mounting, i tried to copy files from a windown to the other window. But Input Output error caused and I can't do it.

I try to use linux command directly, But I get same errors.

I knew that using dd command to make back up. This way may be available to make copy data to the other SD card directly.

At first, New partitions are made in new SD card. the block size is quite same to the original source. I use fdisk and Gparted.

# dd if=/dev/sdc1 of=/dev/sdh1 bs=1024k
# watch -n 60 pkill -USR1 dd

By the second command, we can know how it is progressing by each 1 minute.

I got input output error.

Input Output error
7767+0
7766+0

then changed the option of the command. I'm not sure whether the following command is right.

# dd if=/dev/sdc1 of=/dev/sdh1 bs=1024k skip=7766 conv=sync,noerror

This time, The written partition can't be read. The file system was broken. it seemes mother pc could'nt access to read SD card.

I setted Stay awake option of the phone.

# dd if=/dev/sdj1 of=/dev/sdh1 bs=2048k conv=sync,noerror

i had to change the path of read SD card.

The used size of partitions are different.
