I recently bought a SanDisk Clip+ 4GB on *bay.
It turned on, I could copy some existing music from the player to my PC (still using the OF).
Here comes my mistake:
Before installing RB, I thought of checking the internal flash and ran (being on Windows) "ckkdsk /f D:".
It reported illegal crossreferences and started to repair them, but then seemed to get stuck. I finally disconnected the player and forced Power Off.
Ever since, it won't turn on anymore:
Screen stays black, connecting USB nothing shows up on windows.
I have tried "longpress power button" for almost 1 minute. I have tried holding the middle button while connecting to usb: to no avail.
I hear no popping sound while inserting the headphone. However, when it is inserted and I click the power button (just very briefly, not like longpress for turning it off), I can hear a popping noise, but just for a couple of trials.
I have waited for the battery to drain with the phones connected for several days.
Next thing I thought of was opening the case and disconnect the battery ...
Does anybody have further advice before I do that?
