volume

I have a big problem here. Here is the error message I am getting.

The wrong volume is in the drive. Please insert volume Clickfree_System into drive H.

I have an Clickfree external hard drive and I just secured my network with a wireless router and a password.

It seems someone is possibly breaking into networks here constantly and stealing identities and I would like to know how they are getting into networks unless they are stealing them.

Can someone help with this problem. I am getting corruption in my home.
