random fs corruption with iriver ihp-120, usb2, vfat and 2.6.5

random fs corruption with iriver ihp-120, usb2, vfat and 2.6.5

Reply in email please, i'm not subscribed to l-k.

I guess I'm seeing the same corruption as reported in this thread:
http://www.mail-archive.com/linux-usb-users@lists.sourceforge.net/msg10327.html

If I copy large files to this device and then read it back, I always 
get different md5sums. And random filesystem corruption.

I've learned that the drive in this device, a Toshiba MK2004GAL is 
connected directly to the usb2.0 via a cypress CY7C68310:

Anyone have a patch I can try to address the errors?

I've experienced this problem too, do you find that the device works almost
perfectly if the data is tranferred in smaller blocks?

I tried to find out some information from iRiver before bug reporting this, I
didn't know whether the bug was specifically with my device. However, I found
the tech support department to be fairly atrocious. 

Now that I know it's not something that's device centred I may try taking a look
at the bug (although I'm not experienced at all in this area of the kernel).
