I had loaded my Sansa selectively from my PC’s music library. I believe that when I subsequently connected the Sansa to my PC to power charge it that it tried to sync with my PC’s music library which exceeds the Sansa’s memory capacity. I now get the message “Not enought room for Music DB. Please free 90MB.” I can sometimes see the Sansa in the Windows File Explorer when it is connected to my PC but can’t access the Music folder. I just get a spinning hourglass and Explorer locks up. I can sometimes access Sansa’s Music folder when it is disconnected from the PC by clicking buttons when I get the warning. At times this results in the Sansa refreshing its media before giving me access. However when I attempt to delete files they don’t really seem to get deleted. Any ideas? Thanks!
