Flash MP3 player corrupt file... can run chkdsk? Reformat?

[Muse]

I copied a large (3 hour 175 MB) MP3 music recording to my Sansa m250 2GB and it has a glitch at about 80:00 that causes the file to stop playing. The file I copied to it was fine.I listened to the file as it is on the Sansa from my laptop (playing it off the USB connected m250) and I hear a weird thing at that point sounding like a 1 second segment of another file) but it continues to play when played by the laptop. I have a good version of the file, that's not the problem. I'm thinking there may be something wrong with the m250's flash memory, and wonder what I should do. Should I reformat it from my XP laptop? Can I run chkdsk against the m250 and thereby mark certain memory space as bad like it would (I think) with a HD? Or is there a utility like chkdsk for flash memory?

Limitation of the hardware. I suspect the file system is FAT32 but then a single file would be limed to 4GB. Which isn't the case here. Likely the problem lies in the OS of the unit have a play time limit of 80 minutes. So grab a free MP3 editor and break it up into multiple file.

80minutes of mp3s is not anywhere close to 2gb he already said it was 175mb

if its really a bad bit of flash mem then copying the file into the device at a different point or a second copy should have the problem disappear. its flash mem, no chkdsk for it. it should be managing its own wear/errors.

Ah, that's what I needed to know. Thanks! :awe:

I did reformat the drive yesterday, using my laptop. It's FAT32. I was wondering if maybe the error was due to my means of getting the file onto the MP3 player. I copied the file to a Mac and from there to the Sansa. I suppose it's a problem with the flash memory, though.

usb corruption can happen.
format might work, might not, i think flash disc controllers sorta do their own thing with remapping or whatever for wear leveling the os can't really know its writing to a certain point ever.

You could try creating a large (nearly 2 GB) file on your PC, determine the checksum of the file, and copy it to the flash memory and see if it gets corrupted. It might give you an idea whether the problem is with the memory itself or something to do with the Sansa firmware.
