I removed some external hard drives when working on my computer and when I replaced them, they had different drive letters. Now some of the drive letters I had used before are not in the list of available ones even though these letters are not currently in use and I restarted the computer. I MUST be able to restore the drive letters so that paths will be correct and so my Seagate FreeAgent drive will find the drives to update backups. The computer does have some (Linux) partitions which do not have any drive letters assigned in Windows, maybe this has something to do with it? Help please!
