SumVision cheapo USB-stick MP3 player 512 megs. Very clunky user
interface. Virtually unusable. Eats batteries.

I ripped 110 megs of MP3's to a folder called Highway 61 Revisited/
,
dragged them to the USB drive and they played alright.
So then I ripped a CD to a folder called LondonCalling/ , dragged
and
dropped. It copied about 5 megs worth across and then I got a
message
that the USB drive was full up.

Querying the SumVision system menu, it says I have used 484 meg
(100%).

So, I have copied 120 megs of MP3's to the 512MB SumVision. But it
says
the total file size is 484 megs...

My PC works fine dragging and dropping files to other cheapo USB
sticks.

Any ideas?

Likely that it is formatted in FAT and has lost a lot of memory due to
wasted sectors.

Reformat it in FAT32 and you should be OK.

My guess would be that maybe:

You successfully copied the 120MB file(s) onto the device.

You then tried to copy onto it a file or files that was/were too large
to fit on the device, so the deivice ran out of space before the file
was closed peroperly, leaving the device full, but no partial file
showing up.

Maybe if you remove all files somehow (re-format it?), and copy your files
onto it again but in smaller files, and monitor what free space it reports
after each file has been copied.

Regarding your figure of 484MB : A lot of memory devices these days are
sold as being (e.g.) 512MB, but the MB does NOT refer to (1024*1024) bytes,
but rather (1000*1000) bytes.

Maybe it's not a coincidence, then, that

512,000,000 bytes /(1024*1024) = 488.2 (proper) MegaBytes

I'm pretty sure that I have had 512MB SD flash cards with exactly
this "shortfall problem". They weren't 512*(2^10) bytes, but they were
only 512*(10^6), which as above, is only 488MB.

Maybe in your case, the other 4 MB are used by the FAT (or whatever)
filesystem on there, or maybe some hidden files or something else.

All guesses though.

I'm sending the damn thing back, anyway.
The user interface and controls don't work consistently.
And the unit eats batteries ( 3 in 3 days just messing about with the
menus. I never got to play an MP3).
Any suggestions for MP3 players which are well built with decent user
interfaces?
