Windows 2000 and Windows XP allow the static assignment of drive letters on volumes, partitions, and CD-ROM drives.
This means that you permanently assign a drive letter to a specific partition, volume, or CD-ROM drive.
When you add a new hard disk to an existing computer system, it will not affect statically assigned drive letters.
e.g. I assigned my USB drive the letter K: (secret code for Karaoke) he, he
Everytime I plug it in it is automatically K drive
Hope this helps.
