While testing the speed of my various SD cards, I also tested the internal flash with the command:

Code:

time dd if=/dev/mtdblock4 of=/dev/null bs=8192 count=10240

Which resulted in:

Code:

dd: /dev/mtdblock4: Input/output error
Command exited with non-zero status 1
real    0m 4.02s
user    0m 0.03s
sys     0m 1.60s

Unfortunately, I am not aware of the usage of the dd command, but it hits me odd that it would produce an input/output error.

Should I be concerned?
