Hello kmc2005 et al -
I’m having the same issue… Brand new Sansa Clip 2Gb (right out of the box). I plugged into a Mac Powerbook USB port to charge it up. Left it connected for 1/2 hour (so it got a little charge), then briefly checked the menus – they looked fine. Then I reconnected it to the Mac USB to let it finish charging (2-3 hours). During this time I put the Mac to sleep (by closing the cover). Next time I looked at it, the Clip display was still animated, and showed the “full-charge” symbol, so I unpluged it from the Mac USB. As soon as I unplugged it, the Clip’s display froze… Now with it disconnected, a hard reset will power it off, but it only powers back on to the “SanDisk Sansa” display frozen (with the blue circle illuminated).
I’ve also tried the steps you describe here - slide the power button back to LOCK, then press-n-hold the center button while plugging in (to the Mac). Still just powers up to the frozen “SanDisk Sansa” display… I have a Windows XP Pro machine as well – no luck there either.
So, what’s the deal? Does a Mac = death for the Sansa Clip!? Sure looks that way. This one is “bricked” unless someone knows a better ‘secret handshake’ to make it responsive to re-flashing or some such…
