Install iotop in debian
#apt-get install iotop
This will complete the installation.
Using iotop
type iotop in your terminal and you will get a regularly updated list of processes and the amount of I/O they are currently using: reads and writesin bytes per second, and percentage of time spent swapping and waiting for I/O.
iotop
iotop needs the CONFIG_TASK_DELAY_ACCT and CONFIG_TASK_IO_ACCOUNTING options enabled in the kernel; in Debian stock kernels, that’s already the case.

use the -o switch to view only the process actually doing I/O, instead of all the processes.
[code]iotop -o[/code]
