I can't put songs from my sansa mp3 why

SOURCE: erase all songs on my sansa e250R mp3

Ok
the easiest way is:

Open My Computer and go to your sansa folder named something like this "SansaE250"
Open it and go into music and delete all the songs
simply, press CTRL+ A - selecting everything, then press Delete.

SOURCE: locked sandisk sansa m230

Slide the HOLD switch to the left

SOURCE: computer wont recognize sansa clip mp3 player

Reformat clip with disk utility after looking at it like an external disk. Do this by turning it off. Puting it in lock mode. Hold down middle button as you plug it in.

I am mad at my Clip as it did the same thing.

Screen shot here:
Sansa clip not recognized.

SOURCE: cant put songs/photos/channels/videos on my sansa

NO IDEA GOOD LUCK THOUGH!!!!!

SOURCE: sansa e250...computer will not detect

If you are using a USB connector [that connects extra ports to your computer] it sometimes doesnt work... so if possible hook the USB sansa cable to the main ports in the back of the server. It might also work to hook it in, and then go to 'My Computer' and see if it shows up there. Good Luck =]
