I looked on the internet for information about this player and it says
requires no software and works by simply dragging and dropping files !
sounds good I thought so i've just plugged it in to the Iyonix,
waiting and hoping, the Iconbar icon popped up for the device, yes it
works I thought , then I double clicked on the icon and was presented
with the following message -
"Bad block size - must be 256/512/1024"
If I had to guess, I'd say there's some nonsense in the boot block
(probably 00s.) You could try overwriting it, but keep a copy for
reference. The boot block has an Intel JMP instruction of 24 bits, 8
bytes of other junk, and then the first 16 bit value is the block size
(sector size.) This is almost always 512 (little endian.)
Another possibility is that the boot block looks a bit ADFS-like, and
its therefore not getting passed to DOSFS. You could try looking at the
Resources:$.Resources.[ADFS|FileCore|DOSFS].Messages files to see which
one produces the error "Bad block size - must be 256/512/1024". My
Iyonix is not nearby.
The final, scariest possibility is that the drive is actually more than
one partition, and I don't believe DOSFS can handle that. Manufacturers
use partitions on some flash drives when they want to include additional
drivers or software, and in AMPEG players to protect the system software
from deletion. Reformatting such a drive would be a bad idea, because
you would destroy the AMPEG player's system software. (That's assuming
the drivers in the MP3 player would allow you to write to the sectors
involved in the first place- self-preservation is a good idea.)
