You may safely remove /dev/sdb, first unmounting then 'safely remove'.
system administration -> disk utility

Thanks for the info. Find out what is busy, kill the app and try unmounting again.
Examples.

Is there is any virus(I know viruses cannot run on Linux) , which is trying to run . Should format my memory card.

Why would you suspect a virus?

Because every time I connect my phone in mass-storage mode, how it can be busy ? I suspect a virus or any other programme is trying to run from my card to my laptop.

Instead of suspecting something why not try to find out as examples in the links describe.

Can you help with this problem?
