USB memory stick in Etch

[J.H.Kim <frog1120@gmail.com>]

Hi, eveyone

I'm using LG X TICK  USB memory stick (1GB) in Etch.
In MS windows the USB memory stick can save 1GB data, but in my etch the device can save only 450MB data.
When over 450MB data is to be copied to that disk, the error message "DISK FULL" is prompted.
Is it driver problem?
How can I fix it?

Thanks in advance.
