I'm using a Lenovo machine which runs ubuntu 16.04 which is installed in an external Seagate Hard Disk (of size 1 TB). Sometimes (happens from the beginning of installation) the hard-disk gets disconnected and all the applications partially works or breaks. Reinserting the hard disk does not solve this problem and the only option for me will be to switch the system off and then switch it on.
If I have my browse opened, I would still be able to browse the net, as long as the browser does not close. Or if I resize the browser by dragging it using a mouse pointer, it breaks and I would be forced to close it.
I don't know if this doubt of mine is purely delusional or reasonable but for some reason I believe if the machine goes to that state, there is a chance it could send my passwords/other information to the servers it is currently connected to (that is raw ram memory). Is it true? If not, is there any other potential vulnerability in such a state?
Moreover, if someone wants to access my system badly and knows that my system gets disconnected often from its hard disk and assuming I have a fixed IP address, will he be able to gain access to the raw ram memory? (this question is purely hypothetical, because I don't have a fixed IP in my home)
