Tapeworm,
Thanks for link. I think in my case my Sansa was actually full since it reported 0 bytes available in System Settings/Info. I tried the fixes suggested in the Sandisk notes and forum discussions to no avail. I could never get my PC to show the Sansa file structure or even reformat the unit. Trying just hung the Explorer program. I eventually found that the Sansa can actually reformat itself under System Settings/Format. So I did that and cleared out my 1400+ tunes. I’ll try to avoid overfilling the Sansa in the future by putting all my music on a 32GB microSDHC chip instead of the internal memory. The 2000 file limit should keep me from overfilling it :o).
Regards,
