I have a 1 GB Sansa Clip and a Mac OS X. I was trying to put the latest firmware on my Clip (the file m300a.bin). Every time I dragged the file onto my Clip, it would show that it had copied. Then I’d disconnect my Clip, and it’d say it was refreshing, and I’d check to see if the firmware had been updated. It hadn’t. When I plugged it back in, m300a.bin was gone. After I tried multiple times to update the firmware, I reformatted the Clip. I didn’t realize it would erase EVERYTHING. When I plug in the Clip now, there are no files or folders; it’s completely blank. When I turn the Clip on, it says Not enough space for Music DB. Please free 30MB. Then it shuts off. Is there any way I can get the factory settings back on? And get it to work with my Mac? I had tried dragging an MP3 file into the music folder earlier, and the song would show up on the Clip as a file, but it wouldn’t play. Any help would be appreciated. I’m going to have to return this to the store very soon if I can’t get it to work within the next day or two.
