Frozen sandisk sansa clip
Restart the computer once and try replugging the player again. If it is still a no-go, I would just double-check everything. My Sansa Clip had the same problem after working fine for a couple of months. I reset the player, which solves the freezing issue one time, but doesn't correct it permanently. I did the firmware upgrade and the Sansa Recovery Tool. Then, the computer didn't even recognize that the player was plugged in. So, I used the volume +/recovery method - disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard. I even reformatted the player inside of Windows Media Player. Nothing. I was just about to give up. Then, I restarted the computer, and the player started working as normal. I think that the Sansa Recovery tool, in particular, requires a computer restart for it to initiate correctly.
