If you set Visible="False", the BoundField isn't rendered, so you can't find it.
There are many different ways for what you are trying to do:
1: Add a HiddenField to the same TemplateField as your dropdown. Find that field instead like:
HiddenField hf= e.Row.Find("HiddenField1") as HiddenField;
if(hf!=null)
   ddl.SelectedValue = hf.Value;

Open in new window

2: Another way is use DataKeys
3: You can try setting DropDownList's  SelectedValue='<%#Eval("servdisk")%>' in the markup.
4: You can get the value from DataItem in the RowDataBound like:
DataRowView drv = e.Row.DataItem as DataRowView;
ddl.SelectedValue = drv["servdisk"].ToString();

Open in new window
