It's the size of the special file.  If you want to know the size on the 
device, you'll have to parse the output of df.

But that's not what I meant.  You redirect stderr to a file and then you 
check that THAT file's size is not zero with [ -s $ErrorLog ]

Come to think of it, you should also test that /dev/sba is a block 
device before trying to dd to it using [ -b /dev/sda ]
