Another way, using the DRAC interface + manual firmware update : 
I am trying to update firware for DRAC in PowerEdge 2950 III, I get error about it need flash drive must be non-formatted and not in use. There is a flash drive showing up as G: i think that's what it is talking about, I had formatted that with FAT while trying to update DRAC firmware when i had got Windows drive format window. What is that Flash drive? How can i get it back to state so DRAC firmware would like it?
DRAC firmware update fails, says flash must not be formatted or in use
