Hi all,

Origninally I wrote this thread;

http://www.linuxquestions.org/questi...d.php?t=439459

As I could not get my EM633X1G MP3 player/encoder to work properly under linux, the filesystem always seemd corrupt. However, I've made a discovery: with the drivers "USBASPI4.SYS" and "DI1000DD.SYS" in freedos, the device works! So it might be that this is a drive geometry problem.

But my question is this: How can you mount a USB Memory stick with a different geometry at the command line? I know to use the mount command to mount partitions (e.g. mount /dev/sda1 /mnt/removable) but what if I wanted to mount /dev/sda1 with some other drive geometry? It looks almost like linux isn't getting the geometry quite right! I'm using mandrake 2005LE.

Not quite sure what you mean. Use dmesg to see where the drive is then mount it.

Snag is, I get a lot of errors in dmesg about the device, yet freedos can read it. Here's an example, output from dmesg;

Buffer I/O error on device sda, logical block 6
SCSI error : <0 0 0 0> return code = 0x10070000
end_request: I/O error, dev sda, sector 56
Buffer I/O error on device sda, logical block 7

Info fld=0x0
ioctl_internal_command: <0 0 0 0> return code = 8000002

Additional sense: No additional sense information

there are lots of these, I can mount it, sometimes KDE will but any copy operation results in "i/o error".

What kind of file system is on that device? It looks like the device has a bad sector on it. Or perhaps a file system that Linux can not read. Look at mount.

You might try to reformat it FAT, then BSD, Linux and Microsoft all will be able to access it. What did you use to format it in the first place? And can a windows box read and write to it? I can't say much more. Looks like a bad spot or a format that Linux can't read.
