using dd...
 

i have a question about the dd utility...

say I have some piece of storage hardware... say I fdisk it and then make an ext3 filesystem out of it...

then I dd a large file to this piece of hardware....

does using the dd utility totally negate/overwrite the filesystem I just put in place?

dd writes in raw blocks so if you write directly to the storage device then it will ignore the filesystem. You can however mount the device first and then dd to a file on the filesystem.

thanks man...
