I have been using a 500 GB drive with my 211 and want replace it with a 250 GB drive. And put the 500 GB drive back in my computer. I am using win XP. When I go into disk managment and rescan my drives. The 500Gb drive is displayed for only a few seconds. When I right click on the drive the only option available is delete partition. When I click this option I am told an error has occured. I think that it is now formated in Linxus and windows has a brain fart. Any help would be greatly appreciated. Mike
