Reboot afterwards. The kernel needs to sync the data on disk.

not sure what you are trying to show here

df is for mounted filesystems. dd changes data on raw devices. dd does not change the mounts, and dded data is not reflected on the mounted filesystems, because data was written directly to the device and not via the filesystem. usually when you dd something onto a partition that is currently mounted, you end up with corrupt data, because both filesystem and dd try to write data and overwrite each others data.

exception is read only mounted filesystems, in that case if you write on the device, you will have to unmount and mount again (or reboot and hope that what you wrote with dd makes any sense at all).

hmmm
got it.....
so i must format the secondary hardisk and make it really clean?
format using wat?
mkfs or mkefs
hmmm
can u tell me how to unmount
i know only how to mount but not unmount
thanks

sorry
mkefs=mke2fs
help me thanks

umount /dev/hdc

Make sure you didn't start any processes which are still running while being under /disk1/<somewhere> because that will keep /disk1 busy.
