[NTLUG:Discuss] USB mount problem ??

[Choi Jason]

Hello guys,,

I have a trouble to attach and detach USB memory stick to my laptop.
When USB memory was attached there was no problem, but when it was 
detached,
error message such as "sda: READ CAPACITY failed" was disaplayed.
I don't understand what makes this problem. Is is Kernel configuration?
I think I need recompile Kernel, but I don't know proper option for 
removing
this error.
I hope to hear your tips and comments.
Thanks in advance.
