USB filesystem emulation bug on Sansa C250

[nerdrunner]

When I run Windows XP "Check Disk" on both the 2GB builtin memory and the 2GB uSD card memory using the USB cable, Check Disk complains that it cannot complete.

I have the following boxes checked:
Automatically fix file system errors
Scan for and attempt recovery of bad sectors

When I run Check Disk on the same 2GB uSD card using an SD card reader, it checks just fine.

I think that there may be some small bug in either the USB emulation or the file system emulation.

This bug exists in both Rockbox 3.3 and 3.4.

Have you tried this using the OF too?

Also, it's usually better to use the command-line version of check disk.

It is possible that your cable (or the USB port it is connected to) is not working correctly. I am able to successfully run chkdsk on my c250 running r23172.
