External drive letter

Hello,
I have been using a new external hard drive on Win XP for a couple weeks now. It has been appearing on Win Explorer as Drive F. All of a sudden, it shows up as Drive L. This occurred after a session of hooking up my ipod to sync with iTunes. Does the change in Drive letter represent any issues, or should I just go with it?

 

I find that when I partition my first harddrive, then the cd, and dvd rom give me a cut off point - -- C, D E, ARE THE PARTITIONS, F AND G THE CD, AND DVD ROM DRIVES --I can connect another HARD drive, and the partitions on that will follow from the original after ther cd, and dvd rom drives, -- H, I, J---and it will boot o.k, if I disconnect that - THIS IS ALSO USED INTERNALLY. When I connect another drive, used for data only, without the original second hard drive, it has not caused a problem.
Your ipod has caused windows to move the drive letters.
If it is a data drive, just go with it . I usually do.
I have found reassigning drive letters tends to make a drive inaccessable.
