Here is a small essay I have written for the kind folks at Sansa outlining every problem that I have dealt with the e260. It's a little long, however, it's the most comprehensive list of the flaws this model has had to my knowledge. I apologize that it isn't pertinent to the subject at hand however, it may come handy down the road.
There are several issues I have had to deal with the E260 model. First, at random the player will freeze and cannot be shut off without removing the battery. Next, when used in the USB format that allows drag and drop file transfer, prolonged exposure to this mode causes files to show up on the LCD screen as a "bad track", which I think means corrupted file. Additionally, dragging and dropping folders, not individual files, seems to also start this. Upon going up to the music storage folder, attempts to delete any file are futile. Files claim to be in some sort of state that denies me the power to delete them. If that wasn't enough, these files will in turn replicate and spawn three mysterious folders that have no end to nothing in them and also cannot be deleted. Attempts to use cut and paste to remove files is also ineffective as it acts as a COPY and paste instead. That is not the end.
The previous process can and will continue for ages. As an alternate means of self torture you can switch to the alternate USB mode. In this mode you can sync files using windows media player, an added bonus is that now you have add music file by file and if the sync device thinks a song is a different title or a unworkable type you are schist out of luck. Anyways, the first flaw in this route is that you give up the ability to remove single files as the sync program can only put on and not remove them, at least for me using the latest windows media player. Even so, the files will eventually become "bad songs" and no longer play despite the fact that they were working a moment before. Interrupting the train of thought, between shut-downs files can and will become corrupt. To confuse things even more, sometimes corrupted files magically decorrupt themselves between this period. In any case, following either route gets you to the final stage of the products derangement. One day you will try to turn it on. It will flash the Sansa logo at the startup and then the screen turns shade of purple similar to a bruise. At this point you now have a paperweight because it won't work, and you can't turn it off either unless you remove the battery. I went through all these stages with my first e260 and I fear I'll have to go though them again.
