Actually based on thgis post the problem sounds to me like it is the card and not the file itself or MTP mode. How old is your card, what brand, what size, where did you get it? If the card is going bad then it will look like the song is corrupted when infact the sectors on yout card are going bad.
At first, I too originally thought it might be a flaw in the memory card. BTW it’s a 4Gig SanDisk uSDHC card, so we can rule out any kind of compatibility problems of some other manufacturer.
Now, it would be too long to try and explain every step or test I did, but basically I switched to MSC mode and ran chkdsk /f. It would fix/find 3 problem files, then connect back in MTP mode, delete those 3 files (after the chkdsk fix), and copy them from my computer again in MTP mode.
I repeated that same general sequence 5 or 6 time with sometimes deleting just single files and replacing them, other times deleting whole folders and replacing them, and after each time around I’d switch back to MSC and run chkdsk… and regardless of what order I deleted or replaced the files or folders, chkdsk was always showing a problem (and basically with the same exact files each time also).
At that point it thought… well, it _could_ be a flaw in the memory card, but it _could_ also be a flaw in Microsoft’s MTP or SanDisk’s working around MTP for an External memory card. So, in MTP mode I deleted all my files from the card in the Fuze, changed to MSC mode, and then did a bulk copy of all (over 3Gig) of my files all in one shoot back onto the card (instead of copying only a few things in steps like I had done with MTP). Then ran chkdsk again, and it did not find _any_ problems at all.
Now, this does not totally rule out a possible problem with the memory card, but it sure does look like there is something fishy going on with MTP mode that does not seem to occur with MSC mode. If I _do_ run into any problems in the future with using MSC mode, I’ll try to remember to come back to this thread and post what happened.
Personally, I don’t trust anything from Microsoft to work right. They have a bad track record (dating back all the way to DOS before Windows) of taking something that originally actually did work flawlessly and royally screwing it up lol. But, this _could_ also be some kind of bug or flaw in the way SanDisk has tried to work around MTP with External memory cards (since I don’t remember having had this problem with the Internal memory).
It would be interesting if someone is this forum (or at SanDisk) could track all the people that mention have their Fuze lock up and if it could be found that they were all using MTP mode (and that chkdsk in MSC mode also showed problems). But, that would take a lot of time to find out.
However, we’ve gone way off track here and still have not gotten an answer to the question (when I started this thread)… So, back to that… Is there some shortcut method to switch to MTP mode when connecting the Fuze when it is set to use MSC mode? I know how to make it connect in MSC if it’s set to Auto/MTP, but is there a trick than can do things the other way around? And, just how many other tricks are there by holding down different button positions when plugging it in?
