c140-deleting podcasts

I have been using this C140 for about a year. I use windows explorer to load podcasts and listen to them on the road.

Yesterday, I discovered I couldn’t delete any of the items currently on the player. When I select them, and hit delete, the items disapear from the explorer pane but I noticed that there is nothing in the recycle bin. further after I disconnect the player and turn it on, the podcasts are still there.

I tried formatting it using explorer (fat) but it wont complete.

WinXP Pro.

Any suggestions?
