It was working fine until my Sansa Clip+ started malfunctioning. I pulled the card out while the clip+ was on but it wasnt reading or writing any data to it, since then its been screwed up. I think the Clip+ screwed it up, as I’ve had lots of problems w my Clip+
I suggest to try if it is recognized in a pc, using an adapter. If yes, you could try formatting it which ofcourse results in losing everything on it.
Can I ask what problems you had with the Clip+?
I talked w SanDisk and I’m getting an RMA. I had to get my Clip+ RMAed awhile back.
So far it seems SanDisk has good customer support
