Running SBS 2003. Previously swapping two 250GB retail Seagate USB drives for backup without issue. Backups outgrew the drives. So we switched to two Seagate 1TB internal drives in USB drive enclosures. Drives were assigned with drive X:. Now when we swap drives, the drive letter reverts to F: and the backups fail. Have used this exact setup on other servers without fail.
I have searched high and low for a solution but have not been able to find one...yet.
