New 1 Tb My Passport Is Acting Odd (And Annoying)

Hi just got my new passport, but it acts strange. Basically once I plug it in to my laptop the menu list of what I want to do with it appears (open files, create backup, etc.), which is normal, but the problem is that this menu keeps popping up every 15~30 secs which gets very annoying.

Yet, when I attach it to my sisters laptop this problem doesn’t happen : /

Any help?

Also I have reformatted it to no avail

Edit: I think the problem is that it is disconnecting and then reconnecting over again.

Contact WD Support for  a Power booster cable

since the problem does not happen on your sisters computer it looks like you have a power issue with your laptop
