So I have a HP ProBook 430 that I use for school and I've installed Win10 on it. I've also used a Seagate external hard drive as a backup for many files and I've also locked it with BitLocker. Earlier last month my screen was broken so I had to send it in to a IT office. When I got the laptop back, I tried to open my external hard drive with my password, but it says "incorrect password" every time after I've gotten it back from the IT office. So before I'll travel to the IT office again I would like to see if anyone here has a solution or suggestion to solve my problem.
